The toilet does not drain water well, what to do, the main reasons

If the water in the toilet does not drain well, what should you do? This problem needs to be dealt with as soon as possible, as it can quickly develop into a complete blockage of wastewater outflow. Any plumbing fixtures tend to become clogged if they are not cleaned regularly. Proper maintenance of the toilet allows you to prevent such a problem from occurring, but if there is already a problem with the outflow, it is necessary to use the optimal methods for removing the existing blockage for a particular case.

Among other things, it should be borne in mind that water can not only drain slowly from the toilet: under certain conditions, the water level can rise. As a rule, such an unfavorable development of events is observed if the riser pipe in the area in front of the place where the toilet is connected to it is clogged. Thus, when flushing water from the upper floors at the bottom of the pipe, the pressure at the site of the blockage can increase significantly, which helps push some of the water into the closest toilet. In such an unfavorable scenario, only a qualified plumber can solve the problem.

Preventing toilet blockages

Due to the large diameter of the drainage pipe, toilets become dirty much less frequently than sinks
and bathtubs. If you do not turn the toilet into an analogue of a garbage can, blockages may not form in it for years. Do not flush or throw down the toilet:

Leftover food
Personal hygiene items
Nails
Hair
Cat litter
Cosmetical tools
Plasters
Chewing gum
Tea leaves from a teapot
Coffee
Cleaning cloths
Diapers

If you accidentally end up with things, any objects, or toys in the toilet, put on a rubber yellow household glove and pull them out. Use the toilet only for its intended purpose and this will save you from the lion's share of problems with its clogging.

Float misalignment repair

If the toilet does not fill with water at all, this is unlikely to happen as a result of the float being misaligned. But in the case when it enters the system, but not in the required volume, then the float should be checked for its correct location.

To do this, you need to open the lid - under it you will see water, with a mechanism located in it and a lever, at the end of which a special buoy is attached - a float. It is this part of the device that is responsible for drawing water to the required level, after which it closes the inlet valve. It also happens that the toilet leaks after flushing; this may also be due to the float.

In case of misalignment, it begins to prematurely interrupt the supply of liquid, which ends in the inoperability of the device. The displacer is carefully placed by hand into the required position - after this, the operation of the system should be restored.

Methods for eliminating air locks

Removing plugs using an installed air vent

Before removing the air lock in the heating, you need to find out its properties. The main one is density, which will always be lower than the same indicator of water. Accordingly, the liquid will displace air upward and in the direction of circulation.

Therefore, to remove air, it is necessary to ensure the release of steam. To do this, you should install special devices - air vents and Mayevsky taps. They work on the principle of a check valve. When a certain pressure is exceeded, steam acts on the valve seat. The rod moves, releasing air from the radiator or pipe. After the pressure normalizes under the action of the spring, the rod takes its old position.

An air lock in a cast iron or aluminum radiator can damage the housing. Therefore, when such a situation arises, you need to solve the problem immediately.

Bleeding air in radiators

So, first of all, you should focus on bleeding air from heating devices - radiators. In this case, you should use the already proven option: bleed the air through the Mayevsky valve. This tap is usually installed instead of blind plugs on the radiator, at the highest point. This arrangement implies the accumulation of excess air directly under the valve. In other words, when it opens, the first thing that will come out is air, and then water will come out, which will indicate that the plug in the heating system has been completely eliminated.

To do this, you just need to place a container into which a small amount of liquid will be poured out along with the air. Open the tap and wait until only water comes out, without the characteristic sounds of air bubbles.

We are looking for what is clogged and where

First, you should go to the kitchen, open the tap and see if the water goes down the drain. Do the same in the bathroom. If there is water in both places, then the riser pipe is clogged. In apartment buildings, experts do not recommend cleaning it yourself. You need to call the housing office and wait for plumbers who have permission and the necessary tools. You can only warn your upstairs neighbors not to flush the water while cleaning the pipes.

If water flows anywhere into the sewer drain, it means that only the toilet is clogged. In this case, it is better to immediately change clothes and prepare gloves so as not to get dirty.

Clogged sewer pipe

To effectively remove a blockage that has formed in a sewer system pipe, you need to buy a product containing chlorine from a specialized store. To use the drug to solve the problem of how to eliminate the smell in the toilet, you must strictly follow the instructions on the bottle so as not to harm your health. The product must be poured into the drain hole and left for a while. Most often, the blockage dissolves under the effective influence of a modern household product, and the plumbing fixture begins to function normally. If a household chemical product turns out to be ineffective, then you need to use the services of a plumber to clean the pipe.

The water supply is incomplete or missing

Diagram of a bowl toilet with a vertical outlet.
The toilet does not flush well even when there is little water in the cistern. As a result of the constant flow of water into the tank and the outflow of water from it into the toilet, the tank is not filled to its full extent.

A similar situation when the toilet does not flush occurs due to a malfunction of the float valve. Due to the fact that the valve is not adjusted, the water stops early. In this regard, the tank runs empty, the water simply does not have time to fill. The problem is solved by adjusting the float. Older toilet models have a brass lever that can be simply bent off. Newer models require the float to be adjusted using two plastic latches.

Flushing water will not be possible if water does not fill the tank. A similar situation when the toilet does not flush can arise for several reasons:

Float valve clogged. The valve contains a nozzle, which by its nature becomes clogged excessively quickly with small debris or limestone. To eliminate this situation, you should install the simplest filter in front of the tank. It would not hurt to install a filter directly in front of the valve at the water supply inlet. This problem can be solved step by step:

turn off the water;
remove the pin securing the float handle;
remove the handle and float from the valve;
remove any existing debris from the valve nozzle;
open the water for a few seconds. Thus, the remaining dirt will come out along with the flow of water;
assemble the parts into the final state.

If the blockage occurs due to a foreign object getting into the toilet and it is not possible to reach it, you must turn off the water supply and use tweezers to remove the debris.

Diagram of the drain tank.

The barrel is clogged with slag, the liner is blooming. This problem mainly affects steel pipes. In this case, you just need to clean the liner. To do this you need:

turn off the water;
unscrew the rubber liner of the tank;
unscrew the valve that shuts off the water supply. In the case where a ball valve is installed, it is enough to just open it all the way;
Point a special device into the pipe and rotate it so that the dirt comes out through it. If it was not possible to clear the blockage in this way, then with the device inside you need to turn on the water for a couple of seconds. But before doing this, be sure to place a container to drain the water. If the water comes out in a strong stream and stops, the device should continue to rotate. Then pull it out through the clogged area. After these steps, the water will flow at normal pressure.

It should be clarified that polymer and metal-plastic pipes are not susceptible to water blooming. Having paid once for reliable pipes, you won’t have to worry about fixing the problem.

Break up the clog with a toilet auger

If the plunger does not give the expected results, you can use a stronger tool. A toilet drill is a sharp metal wire that runs deep into the plumbing system. Its spiral line connects to a long handle so you can control and push the auger.

Take a toilet snake and twist the metal spiral line counterclockwise. Hold the handle firmly and keep turning it to reach the lock. When the drill's corkscrew touches the clog, it stops for a moment.

This means you have to give it an extra push to overcome the obstacle. The best thing about augers is that they collect a lot of debris at the outlet, so the pipes become cleaner after cleaning.

If necessary, you can repeat the entire process to ensure that the drains are not clogged. However, be careful when drilling because the auger is sharp - it can scratch the drain, make cracks or even drill a hole in plastic pipes.

Clean the toilet with mechanical tools

The first tip is to use a special tool and clean the toilet. Don’t wait for the toilet to clean itself – it’s too difficult; it’s better to clear the clog yourself. Luckily, there are several tools you can use to clear clogs.

Pump it up with a toilet plunger It's time to remove the toilet plunger from under the sink - or wherever you've been keeping it. Place the plunger cup over the drain hole, making sure the tool covers the porcelain very tightly.

After this, start pumping up and down by pushing and pulling the plunger with your hands. Don't forget to wear rubber gloves so they won't hurt your hands when diving. The plunger forms a vacuum seal that forces the clog out.

Continue applying pressure until you dislodge whatever is causing the toilet to clog. When the clog is cleared, you will hear gurgling sounds from the pipes. This is a sign that you can remove the plunger and allow the water to flow out of the bowl.

Drain channels are clogged

The tank is filled with ordinary water, which contains mineral salts. Over time, they are deposited on the surface of the tank walls and working elements. Such growths are called hardness salts or lime deposits. Based on the fact that the drain holes are relatively small in size, lime deposits clog them, leaving a small gap for water to pass through.

In order to get rid of this problem, leave approximately 1 liter of water in the tank, but no more, and carry out chemical cleaning using one of the recipes:

Pour 100 g of 5-7% phosphoric acid solution into the tank, and after 10-15 minutes rinse with water.
Add 0.5 liters of borax and vinegar to the water in the tank. After 2 hours, rinse with water.
Add 3-4 bags of ordinary citric acid to a tank of water, and rinse off after a couple of hours.

It is convenient to carry out this procedure late in the evening, leaving the acid inside the tank for the whole night.

As a preventative measure, you can install a coarse filter at the outlet, which is also the input.

If for some reason this cannot be done, then there is another way - tablets for the tank. Their effect is based on softening water and cleaning the entire drainage system. These tablets are produced by different manufacturers, but they are all quite effective.

Ways to fix sewer problems

In order to try to remove a blockage in the sewer drain of an apartment or house, you must first determine the location of the blockage.

So, if a problem with water outflow is observed in the kitchen sink, and all other drain points are working normally, it means that the garbage plug has formed specifically in the siphon under the sink. In the same way, you can identify blockages under the sink in the bathtub or under the bathtub/shower stall itself. Depending on the location of the plug, chemicals such as “Mole”, etc., can be poured into the drain hole in accordance with the instructions and eliminate the problem of deposits on the pipes.

As an aggressive anti-clog agent, you can use simple soda mixed with hot water. That is, first pour soda into the hole in the bathtub or sink, then fill it with hot water. After this, vinegar is poured into the hole. The reaction of the components should push the plug or simply liquefy it.
You can also use a standard plunger to remove a blockage in your home drain. Cleaning is easy with it. You need to fill the plumbing fixture with water and tightly cover the drain hole with a plunger. Now you should make rhythmic movements up and down with the plunger, creating a vacuum in the manifold. Under its influence, the plug should either come out (most often it is hair) or go into the waste system. You can clean the sink and toilet in a similar way.

Why, when the apartment upstairs is flushed, does the water in the toilet downstairs also drain?

What you described is correctly called a water seal failure.

The water seal is the water standing in the toilet opening and in the siphons of the bathtub and sinks. This water seal prevents odors from the sewer from rising into our apartment.

Why does he break down? Because the top of the drain pipe (the thick pipe in the toilet that runs through all the floors and goes out to the roof) is clogged. In winter it can become clogged with snow and ice. In the summer - maybe they shut it up with some hooligans. Call your management company (housing office, or whatever it is called), explain the situation, the plumbers will go up to the roof, clean the pipe and everything will work out.

the system chose this answer as the best

In multi-storey buildings, the sewage system is designed in such a way that the toilets of all adjacent bathrooms (from the top to the first floor) “hang” on each central riser. Moreover, in order to prevent a vacuum from forming in the riser when draining water (the water moves down like a piston, creating a rarefied space behind it), the upper end of the riser is brought to the roof and a valve should be located at its top point (sometimes there is simply a rain fungus instead) ), preventing air from escaping from the sewer, and, on the contrary, allowing air to enter inside it, just to relieve the vacuum during flushing. If the valve is faulty or the upper end of the riser is clogged, then what you described in the question happens. You need to call a plumber and have him provide air access to the drain.

Sewer system malfunction

A malfunction of the sewer system, for example, if you live on the ground floor, when the sewer pipe is combined with a storm drain line. All it takes is a good rainfall and your sewer system will work intermittently.

It’s winter outside, and due to an incorrectly adjusted shut-off valve in the tank, the water does not close, but constantly flows into the sewer in a thin stream and freezes in severe frost. If the sewer pipe is not dug in at the proper depth, a blockage is guaranteed. The sewer does not clog, but freezes.

In this case, you need to contact the housing office or the management company for servicing the local area. You most likely won’t be able to fix this on your own; you need a professional plumber.

If the riser is thoroughly clogged and the plumbers cannot clear the blockage, you will be prepared to have to disassemble the plumbing, remove the casing, for example, when installing a wall-hung toilet, disassemble the toilet itself, remove the drain pipe and corrugation. Prepare for unpleasant odors and the sight of sewage and feces on the floor. It's better not to see this for the faint of heart.

For the future, we recommend installing a non-return valve in the sewer pipe. The valve costs an average of $150-200, but you can choose cheaper models. If there is no free space to install a check valve, you can use sewer check valves with internal installation.

check valve

This check valve allows you to swallow the entire contents of the toilet, but will not allow you to “vomit” anything back.

Check valve assembly

The check valve concerns exclusively the first floors of an apartment building.

If residents of the upper floors very willingly flush feminine hygiene products and rolls of toilet paper down their toilets, then in the basement this lounger can very easily become clogged and water will begin to rise up the pipe in a column.

But it will only go up to the first toilet, i.e. to the first floor. And then from the toilet on the first floor it will flow onto the floor. Those. Simply put, everything that people wash off from the upper floors, at a certain moment they will begin to wash it all off onto the floor of the first floor apartment. And if you encounter a similar situation, then a device such as a check valve can be a salvation.

Loose stools. What to do

If you have soft, too frequent, loose stools for a long time, this indicates a malfunction of the gastrointestinal tract. To get rid of diarrhea, you need to understand the cause of its occurrence. Try to strengthen your stool with foods that strengthen it. These are unripe bananas, applesauce, rice, fatty meat, broth, baked goods, mashed potatoes.

An excellent home remedy for diarrhea is black peppercorns. Depending on your body weight, take 10-15 pieces and swallow with water.

When diarrhea continues for more than three days or there is blood in it, you need to consult a doctor and have a detailed stool test done.

The tank does not fill

The float valve is clogged. Water carries with it mineral salts, sand and scale dissolved in it. Sooner or later, the bottleneck - the valve nozzle - inevitably becomes overgrown.

Advice: a coarse filter immediately after the valve will not remove salts from the water, but will retain all large suspended matter and sand.

Turn off the water to the tank.
Pull out the pin that holds the float lever.
Pull out the lever and valve that shuts off the water.
Clean the nozzle located behind the valve with a thin wire. Then turn on the water for a short time so that the remaining sand and lime is washed away with water. If the valve becomes clogged with debris again during flushing, clean it again.
Reassemble the float valve in reverse order.

Damage to enamel

Ceramic toilets, the most common, are coated with a smooth glaze or enamel

Over time, the coating wears out, and when struck by carelessness, scratches, chips and cracks remain on it. As a result, the smooth surface turns into a rough one and begins to resist the flushing of sewage.

Damage to the enamel is a sure sign that it is time to purchase a new toilet, but if there is no opportunity to do this yet, they resort to temporary restoration:

After rinsing and drying the toilet, rough areas are treated with fine-grained sandpaper;
thoroughly wash the toilet so that no dust remains, then dry and degrease;
waterproof sealant or ceramic putty is applied to problem areas;
after waiting for the mixture to dry completely, paint the treated areas with powder paint using a paint gun;
wait for the paint to dry completely (about 3 days are required) and resume operation of the device.

The improvised glaze does not last long, so it is recommended to plan to purchase a new toilet in the near future.

Ways out, depending on the situation

Elimination of interruptions in the operation of toilet plumbing is determined by the nature of the problems detected. This can be either a simple “click and fix” solution or a whole range of different measures.

To solve the problem yourself, you must first identify the source of the problem.

Incomplete tank

Most often, this type of problem is caused by breakdowns in the operation of the shut-off valves or simply by poor adjustment. First of all, you should check the operation of the float and drain button. If they are in order, you need to examine the condition of the sealing bulb that holds water. It happens that the reasons why the toilet does not flush well are that the seal material is worn out and the water slowly leaves the tank without the inlet valve activating. Naturally, its volume also decreases.

If the tank is constantly leaking, then it simply does not have time to fill with liquid, because it is constantly draining.

Blockages

There are two types of blockages: a blockage in the toilet channel itself (and the siphon) or obstruction of the sewer pipes. In the first case, you can clear the stagnation by simply pouring boiling water (you need to be careful not to crack the bowl body) or with a pipe cleaner. Otherwise, you will have to resort to mechanical procedures: use a plunger or a special cable. Sometimes you also need to clean the neck - for this there are special tablets that are added to the water.

A clogged drain is one of the reasons why a toilet may stop flushing.

Poor or no water flow in the tank

Even slow filling of the storage tank makes it impossible for the toilet to operate normally. If the water stops flowing completely, the source of the problem should be sought in the operation of the shut-off valve. Also, the reason why the toilet in an apartment does not flush well could be a leaky float or the supplied water contains sand and clay suspensions, which quickly clog the outlet. In this case, everything can be done with basic cleaning.

It happens that scale gets into the sewer, which clogs the hose.

Damage to the coating

This reason is not obvious to many, however, it can also lead to slow water drainage. Salt deposits, rust deposits and cracks in the enamel significantly affect the flow rate and ultimately lead to poor rinsing. This problem can be solved either by completely replacing the toilet bowl, or by restoring the coating.

A very common reason for poor toilet flushing is damaged enamel.

Roughness, cracks, scratches and chips prevent waste from completely entering the sewer system.

Leaking toilet tank

Fixing the problem of a leaking tank is a completely doable task, but quite troublesome. First you need to look at the reasons for this problem:

Diagram of the drain tank.

The bulb seat is clogged. It needs to be cleaned.
Deformation, wear of the pear. Complete replacement of the pear. They are sold freely in plumbing stores.
Destruction of steel (plastic) bolts. Because of this, water flows through the holes to the shelf. In this case, it is possible to either replace the damaged bolts or completely replace the complete set.
Float deformation. In this case, the float allows water to pass through, loses its tightness, and its weight increases. As a result, it sinks, which affects the operation of the toilet. To solve the problem, you need to dismantle the float and install a new one. If it is impossible to make a replacement, it is necessary to seal the damaged float. Sealing is carried out using plastic, which fills the cracks in the molten state. After which the float is placed in a plastic bag and attached to the lever.
Damage to the siphon membrane. In this case, the membrane should be replaced.

To do this you need:

drain water;
unscrew the nuts securing the tank to the flush pipe;
slightly unscrew the siphon nut at the base of the cistern;
dismantle the siphon;
change the membrane;
assemble the parts in the appropriate order.

Problems with the tank

Problems with the tank most often arise for three reasons: due to improper installation; after incorrect setting of the fittings; as a result of wear or breakdown of individual components and elements. If there is too much or not enough water in the tank, first of all, it is recommended to check the condition of the float.

If it is held by a thick wire lever, adjustment will be easy. It is enough to slightly bend the metal so that the float changes its position. If more water is needed, the float must be moved higher. To do this, the wire is bent in an arc downwards.

Tank damage

Sometimes the problem is to look for in the tank itself. Most often, the tank is damaged due to improper use of the washing machine. If people wash their shoes frequently or don't remove change from their pockets, metal objects can damage the tank.

If the seal of the tank is broken, it will have to be replaced. In this case, you need to call a technician to order a new part.

These are the most common problems that arise when operating washing machines. For a more complex breakdown, it is better to seek help from a professional.

You can install leakage protection on your washing machine. Some devices come complete with full or partial protection. With partial protection, the machine is installed on a special tray with a float and a switch. If water leaks inside the machine, the protection is activated and the machine goes into emergency mode. Washing machines equipped with full protection against leaks are, in addition to the tray, equipped with a hose with a solenoid valve that closes if a leak is detected.

You should not try to fix the problem if the device is under warranty. This is a violation of warranty, and all possible consequences fall on the hands of the master.

You can fix your washing machine if it is leaking from below. Most of the reasons why this malfunction occurs are easy to eliminate. However, you should not do this without having minimal skills in working with technology.

Frequently asked questions

Since the design of all toilets is almost the same (the differences are unimportant and in our case may not be taken into account), some points can be addressed immediately, before unsolvable issues arise during the troubleshooting process.

Most problems arise due to the same reasons, so advice is always very useful.

The choice depends on the age and condition of the plumbing. If the toilet is old and uncomfortable, it is better to replace it. At the same time, it is necessary to take into account the specifics of the problems - sometimes replacing the device does not solve the problem.

We need to find out which node is the source of the problem. If the condition and performance of the second node are quite satisfactory, it is not necessary to change them.

The easiest way is to increase the volume of drained water. You can adjust the reservoir (newer models have several options for adjusting the valve). If the problem cannot be solved, you need to purchase a larger capacity tank.

It has already been said that it is more correct to act mechanically - to use a cable. The most effective method is hydrodynamic cleaning, which can be done using a Karcher car wash or similar.

Sometimes the problem is successfully solved with the help of an air valve, which is installed on a horizontal section of the sewer pipe. It balances the pressure in different parts of the system, allowing the air lock to be released freely. However, some models of such valves release foul-smelling sewer gases into the room, which is unacceptable in apartments.

It is important to keep in mind that eliminating one problem does not always give the expected result. Often problems occur in pairs or in larger numbers. Therefore, if the result turns out to be unsatisfactory, you should not despair, but look for additional causes of the problems. In any case, eliminating the causes automatically solves the problem, you just need to take all the necessary measures.

Toilet flush systems

The most effective flushing occurs when the tank is located as high as possible from the toilet itself. A container of water, located almost under the ceiling, gave a powerful stream that swept away everything in its path.

Such designs were common in Soviet times. Nowadays they can only be seen in public toilets. The abandonment of such a system in residential buildings occurred due to the high noise level during operation. She also spoiled the appearance of the home bathroom.

If the water quality is poor, deposits occur under the rim.

Let's look at flushing methods using the example of the most common "Compact". The system uses two types of flushing:

soulful;
cascade.

In the first case, the water first rushes through the channel under the rim. Then it falls down, evenly washing the bowl. In the second, the water flow is discharged along the rear wall.

The disadvantages of the latter method are immediately obvious. The side and front walls of the toilet remain unaffected. The circular (shower) method ensures complete cleanliness of the entire bowl, but the back wall suffers. As a rule, all the sewage accumulates on it, and the flow power for cleaning may no longer be enough.

But such designs are already a thing of the past and can only be seen in hospitals.

Main reasons

Often the toilet does not flush well due to problems with the water drainage system itself. To solve the problem yourself, you must first identify the source of the problem. Let's look at the possible causes of the problem.

If the water stagnates, then most likely there is a blockage in the sewer. When the liquid passes, but slowly, this means that the blockage is small.
The drain tube is small in diameter. With prolonged use, deposits appear on the walls, which interfere with water circulation. The pipe can become overgrown with them, then only 1/3 of the original diameter remains. This happens especially quickly if water is supplied from underground sources. In this case, it is enriched with mineral salts, which additionally clog the drain.
It is worth checking whether there is water in the tank itself. It happens that scale gets into the sewer, which clogs the hose. Also, the flushing process may be disrupted due to the lack of a tank lid. It must always be reinstalled.
Debris may have gotten inside the drain. Sometimes it's even rubber hoses from the float valve. They are used to ensure that water from the sewer is collected as silently as possible. Usually the hose comes off if the reservoir cap is not in place.
The float valve is not adjusted or is set incorrectly. As a result, it shuts off the water supply prematurely.
The tank is constantly leaking. It simply does not have time to fill with liquid, because it constantly drains.
The float valve is clogged with debris. Its design has a nozzle into which scale or grains of sand can fall. This does not happen if a filter is installed in the hose in front of the tank.
The line to the tank is clogged with some debris or overgrown. This problem is especially relevant if the house has steel pipes.

In a private home, problems with the toilet look a little different. The sewage system here is arranged differently than in apartments. Often, standards are not followed during installation, so the liquid flows slowly. Experts identify a number of reasons for poor water permeability associated with poor-quality installation and the devices themselves in general.

No fan boner. This pipe serves as ventilation for the sewer system. It allows the accumulated gases to escape. In the absence of a vent riser, air plugs form inside the pipes. Because of this, the water stops or simply loses speed. There is an accompanying sign of this problem: gases still find a way out of the sewer. In this case, an unpleasant odor can be heard from the toilet, bathtub and sinks.
Incorrect pipe slope. The problem is related to improper drainage in general. The reason may be either in the section that leads to the septic tank or in the section that leads to the connecting pipe. There is no simple way to fix these problems.
Poorly designed toilet. If the plumbing itself is new, then that may be the problem. A toilet bowl with a shelf often becomes a source of trouble for its owners. Modern models often have a drain in the center or with a slight slope. In this case, the bowls are shaped like funnels.
Location of the drain hole in the toilet. Just one water outlet in the center will not do the job. Flushing in a circle is much better and more durable.

Sometimes the reasons are even more banal. For example, models with a button are fraught with danger. Especially if the tank cap was removed and installed incorrectly. In this case, you may notice that the toilet constantly flushes a small amount of water.

It's not just plaque that can clog water drain holes. Sometimes a simple piece of paper thrown into the toilet also leads to similar problems. It can also cling to deposits inside the drain pipe. In this case, the water does not drain or does so too slowly.

What to do if the water in the toilet does not drain well?

Problems with the fan riser

fan riser
In short, the sewer fan riser is nothing more than ventilation.

Its main task is to ensure air flow inside the sewer system, which ensures its ability to quickly cope with the transportation of large volumes of water and remove unpleasant odors.

Let's be honest - the relevant housing office services have a negative attitude towards the issue of removing this part of the riser, even if it is being replaced with an air valve. Why?

Everything is simple here - its absence entails a lot of problems that begin to fall one after another on their heads. And although these troubles can be counted on one hand, they can make life unbearable for residents of a high-rise building. Such problems include the following.

foul odor
problems with the sewer system

In addition to draining the water seals, the absence of a drain pipe certainly affects the operation of the sewer system - as a rule, it begins to clog more often. The lack of the same full air flow does not allow the system to quickly and effectively remove human waste. This nuance is especially true for sun loungers - if before you had no trouble with them, now you will have to clean them with enviable regularity.

Now decide for yourself whether you need a fan riser in your apartment or maybe it’s better to put up with its presence? By the way, if you are a resident of a private house, then you should not think that you will not have such problems. It should be understood that no matter the size of the sewerage system and no matter how correctly it is assembled, the drain riser is its integral part, and its full replacement simply does not exist.

Why does the water in the toilet drain poorly after flushing?

What kind of blockages can there be and how to determine their cause

All sewer blockages are divided into several types:

adhesion of fat to the internal surfaces of the pipe and adhesion of other waste. Such a blockage is usually called operational;
the mechanical appearance differs from the previous one in that the cause of clogging is the entry of a foreign object into the system;
as a result of the appearance of a fatty layer, a siphon blockage may occur;
There is also a man-made problem, the cause of which is an error during installation of the system.

If the main access riser on the lower floor becomes clogged, then all the contents in the pipe rise up and come out in someone’s toilet, bathroom or kitchen. In such situations, you need to urgently call a specialist, since it is unlikely that you will be able to fix the problem yourself.

Finding an air lock in a sewer pipe

Ways to solve the problem

You can use regular soda to clean drains. To dilute the correct solution, you need to prepare several liters of boiling water in which a pack of soda will dissolve. The prepared liquid should be poured into the drain hole, and it is recommended to gradually add vinegar. In this way, a reaction can be achieved that will promote the rapid decomposition of fat

Most often, this method is used if there are no special means at hand, which include Mole, Tiret, etc. You can use chemicals yourself, but it is important to follow basic safety rules. Immediately before cleaning the sink, toilet or bathtub, you need to familiarize yourself with the operating instructions for a particular product. It is better to use this cleaning method when the pipe is not yet completely clogged, this way you can achieve greater efficiency

When the drain is completely clogged, it is dangerous to use chemicals because they can back up into the bathtub or sink. A proven and reliable method of cleaning is to use a simple plunger. When actions using soda or chemicals do not bring much effect, then this method can be used. In such cases, it is important that the bowl of the plunger completely covers the drain hole.

When the drain is completely clogged, it is dangerous to use chemicals because they can back up into the bathtub or sink. A proven and reliable method of cleaning is to use a simple plunger. When actions using soda or chemicals do not bring much effect, then this method can be used

In such cases, it is important that the bowl of the plunger completely covers the drain hole.

How to fix the problem using a plunger?

Actions are performed in a certain sequence:

a sample filter is removed from the hole;
the top hole of the bathroom must be tightly closed to achieve greater efficiency during the work process;
The plunger must be installed so that no air lock appears, while the handle is placed vertically;
without lifting the device from the bottom of the bathtub, you need to move the device up and down;
on the last movement, the plunger rises from the water to check the effectiveness of its drainage. If necessary, the procedure is repeated several more times.

Another proven device is a metal cable, which is often used by plumbers. At one end of such an object there are fluffy wires, on the other side of the cable there is a handle for convenient use. The first end is inserted into the pipe, and rotational movements must be made using the handle. Depending on the degree of pipe clogging and the location of the problem, cleaning can take a relatively long time. If the problem is solved quickly, then the length of the cable is sufficient to effectively penetrate the sewer.

Hydrodynamic pipe cleaning

If all known means are ineffective, it is recommended to use a special technical device with which hydrodynamic cleaning is carried out. This method is considered very effective.

Such machines differ in power and overall dimensions. It is allowed to clean pipes whose diameter can be 5-100 cm.

As a rule, all hydrodynamic devices operate on the same principle, regardless of their power and size. A nozzle is placed on the end of the device, through which a stream of water is supplied under high pressure.

The flexible hose ensures maneuverability of the device, which is important for achieving a positive result.

Some people often wonder whether it is possible to use such equipment at home and what are the costs? In answering these questions, it should be noted that to clean the sewer system in an apartment it is not necessary to buy special equipment. It’s easier to call a specialized organization. If there is a need or your financial situation allows, you can buy a mini-device for use in a country house.

Air lock problem

Nowadays, plastic pipes are very popular, which are distinguished not only by good performance characteristics, but also by easy installation. Not everyone who installs plastic pipes is a specialist, so when choosing consumables for installing a sewer system, various types of mistakes can be made. Common mistakes when choosing and installing a system include:

incorrect determination of pipe diameter;
unnecessary turns during the installation process;
laying sewer pipes at the freezing level of the ground;
lack of means in large areas to control the operation of the system.

The most difficult issue to resolve is that of an air lock in the sewer; not everyone knows how to fix this problem. If it is serious enough, then there may be a need to rebuild the entire sewer system. Before making such drastic decisions, you need to try to eliminate the problem yourself, using some simple methods.

How to get rid of an air lock?

If an air lock appears in a specific section of the pipe, for example, in the sink drain in the kitchen, bathroom or toilet, the essence of the problem may be:

in the farthest location of the plumbing fixture from the riser;
due to an installation error when pipes were installed with the wrong slope.

To solve such problems, you can simply re-lay the sewer sample to the riser, taking into account the correct level of inclination. In some situations, it is enough to simply raise the plumbing fixture to the required level. Thus, due to the level difference, you can get rid of problems with an air lock.

If there is an air lock in every plumbing fixture, then most likely the design of the air duct was not thought through during the installation of the system. In such a situation, it is recommended to make an open sewer riser on the roof, through which air is released from the pipeline. If this is not possible, you can install air valves that can allow air to flow in one direction.

There are situations when an air lock forms during the installation of an air duct. Then you need to check its performance.

If the measures taken to eliminate the air lock in the sewer are not successful, then the only solution is to lay new pipes.

No water comes out of the toilet. When flushing, the level rises

A classic case of a clogged drain. There was something in the toilet that was too hard or large to fit through the outlet.

First, find out what caused the blockage.

Repairing a toilet boils down to removing the plug from it; Each type of blockage has its own solution.

Construction waste, broken glass or crockery, solid food waste. The good news is that in this case the water goes away, albeit slowly. Flush several times to clear the water in the toilet. Then, alas, you will have to put on gloves and climb into the toilet

Take out the garbage carefully and slowly: cutting yourself in this case will be especially unpleasant, and sepsis is possible

Please note: flushing the last few clogged items down the drain and being too lazy to remove them is a bad idea. In this case, there is a high risk of causing a blockage down the riser.

May flood your neighbors on the first floor

In this case, there is a high risk of causing a blockage further down the riser. May flood your neighbors on the first floor.

Sand, cat litter and other soft inorganic substances. You cannot do without a plumbing cable. Use it to pierce the clog to remove it from the sewer and allow the water to flow out; the residue will have to be washed off with water from a hose or simply by flushing water from the tank over and over again and rotating the cable in the toilet. Alas, in this case we will be forced to flush the clogged item down the drain: removing it from the toilet is problematic.

A plumbing cable is one of the most useful tools in any home.

Paper, soft food waste and other organics. There are a lot of options here: You can use the same plumbing cable;
Chemicals for clearing clogged pipes (like Mole) or any other alkalis and acids will destroy organic matter in a couple of hours. You just need to fill them so that they come into contact with the stopper in the toilet;
Often the blockage can be easily cleared with a regular plunger;
In its absence, you can similarly use a large plastic bottle with the bottom cut off.

Chemistry can help in this case

Improper installation of sewerage

The next reason is improper laying of sewer pipes, incorrect slope. The diameter of the sewer pipe is incorrectly selected. The diameter of the sewer pipe should be approximately 100 mm (10cm). It happens that construction debris, sand, or mortar gets into the pipe, as a result, the passage of the pipe is reduced and then the ingress of hair, cotton wool or wood litter for cat litter firmly clogs the toilet.

The quality and defects of the toilet itself, you purchased a non-certified product, for example, in China, with a small drain neck with a mousehole diameter of 50 mm.

Installation of sewer pipes is carried out at a slope within strictly defined limits.

If the slope is small, the liquid simply will not flow down them, and if the slope is too large, the water will drain quickly, but the contamination will remain in the pipe.

pipe slope

Paradoxically, excessive “leaking” of the sewer pipe leads to chronic blockages. SNiP give the following values for MINIMUM slopes of sewer pipes:

With diameter

50 mm – 30 mm/m.
110 mm – 20 mm/m.
160 mm – 8 mm/m.
200 mm – 7 mm/m.

The MAXIMUM slope should not exceed 150 mm/m, with the exception of bends for plumbing fixtures up to 1.5 m long. Connecting sewer pipes at right angles is allowed only in a vertical plane.

Let's sum it up

As you can see, there are not many reasons why water may leak in the toilet. Therefore, in principle, even an untrained person can cope with the problem.

It is only important to carefully read the instructions and act consistently and carefully. Then everything will work out - the toilet will work without failures. Is your toilet tank leaking? Well, let it flow - it’s not the biggest problem

After all, the flowing water will still flow into the sewer. And many homeowners think so. Until you receive a bill for your water consumption

Is your toilet tank leaking? Well, let it flow - this is not the biggest problem. After all, the flowing water will still flow into the sewer. And many homeowners think so. Until they receive a bill for the water consumed.

After this, they come to a belated understanding of the danger of the situation when your own money flows from the tank into the sewer, almost before your eyes. Therefore, a leak in the toilet flush tank must be repaired immediately, immediately after discovering this defect in the operation of your plumbing equipment. And in this article we will tell you how this is done.

How to fix a leaking toilet cistern if you are not familiar with its design? Of course not. Therefore, before reviewing the repair technology, we will dive into the structure of the object being restored.

A typical tank consists of the following elements:

Float valve (faucet)
- a fitting connected to the water supply system, on which a shut-off unit controlled by a float is attached. If there is no water in the tank, the float pulls the valve shut-off element down, opening the fitting. When the tank is filled, the float rises up, closing the fitting.
Overflow
- a hollow column connected to the toilet. This column protects the tank from overflowing. When the water level reaches the edge of the column, the liquid will overflow into the toilet rather than rush into the toilet room.
Drain valve
- a hatch mounted on a hinge that closes the drain hole leading to the toilet. If the hatch is closed, water from the float valve fills the tank. If the hatch is open, then all the liquid accumulated in the tank flows down the drain hole into the toilet.

drain lever

– drain valve control mechanism. This unit consists of a rack with a rocker arm, the edge of which is connected to the valve (hatch) with a polymer or metal chain. By pressing on the free edge of the rocker, you pull the chain up and open the valve hatch. By releasing the lever (yoke), you loosen the chain and lower the hatch into place.

Of all the components described above, only the first three elements can provoke a leak in the toilet - tap, overflow, valve. Therefore, repairing a toilet cistern leak involves restoring the functionality of these particular components.

As you can see: there is nothing complicated in the design of the drain system. But enough theory, it’s time to move on to repairs.

Where to start the renovation?

Of course, starting with finding the cause of the water leak. After all, only by understanding why the toilet tank is leaking will you be able to eliminate the defect and establish normal operation of the drainage structure.

And there may be several reasons for this, but most often plumbers deal with the following options:

The first option is a leak through the overflow

– Diagnosed very simply – water is constantly flowing in the toilet cistern. It’s as if we have a bottomless structure in front of us, and not a container of 10-12 liters (or even less). Therefore, if you hear the murmur, get ready to change or repair the parts of the float valve.

The second option is a defective sealing gasket.

– noticeable by a constant stream that forms a characteristic limescale “drip” on the inner surface of the toilet bowl. If you see it, get ready to dismantle the tank and change the gasket.

The third option is a weakened drain valve.

– diagnosed by an intermittent stream flowing from the drain nozzles into the toilet bowl as water enters the tank. Therefore, if, while filling the container, water flows from the tank into the toilet, without any options, get ready to change the valve shut-off element.

As you can see: there are not so many prerequisites for the formation of a leak. However, each of them requires its own approach to repair. Therefore, next we will consider three technologies for eliminating leaks, linked to three reasons for its formation.

Septic tank overflow

In a private home, the cause of problems with flushing may be an overflow of the septic tank. Then the liquid simply cannot come out of the toilet, and urgent measures need to be taken. There are several reasons:

volume is too small - not designed for the actual amount of wastewater;
the increasing level of edge water - especially in spring, leads to the fact that water floods the cesspool and it overflows faster than it should;
siltation of the walls and bottom of the container - the crust prevents the passage of water into the ground and the pit overflows faster;
freezing of the soil - leads to the same picture, only now the ice crust does not allow liquid to seep into the ground;
clay soils - such soil initially does not absorb water well, so the pit always overflows.

To remove the problem, it is necessary to invite sewer trucks and pump out the contents of the cesspool. After this, you should inspect its walls. If they are silted or covered with greasy deposits, this layer of soil must be removed with a shovel and disposed of outside the residential village.

Chemical cleaning methods can be used to dissolve some of the deposits and make the job easier.

Conclusion

In order to eliminate a malfunction in the toilet, as well as an increase in the water level in the bowl, you first need to establish its cause. If it is associated with a simple blockage, then, as a rule, it is possible to eliminate it yourself. More difficult problems should be dealt with by experts.

From the video in this article it is possible to glean additional information on this topic.

Help me please! Yesterday there was a problem with the toilet. Inadvertently, I threw some stinking rice in there (a little), and it washed off the second time. But now, when you flush the toilet, the standing water goes down, as if it is sucked in and returns to its place again. At the same time, a gurgling sound appears in the bathroom. What is this? There seems to be no blockage, since the water is washed off well and quickly. But this gurgling sound scares me, and the fact that the water from the toilet goes down and then returns to its place.

A very unpleasant situation happens when you flush, but the water in the toilet does not drain well, along with all the other “good” things, and the toilet does not flush the first time. This situation often happens if you move into a rented apartment, it seems like the toilet isn’t clogged and everything is clean, but the water doesn’t drain well, and there’s an unpleasant smell.

There may be several reasons why the water rises up and then does not drain well, and the feces in the toilet are not flushed away. The situation is not pleasant, many do not know what to do, they try to clean it with a plunger, but this does not always help.

Reasons why water rises

The source of troubles with a toilet - poor flushing - can be either breakdowns or an unsuccessful design of the bowl or drain system, and in a private house it can also be errors in planning the sewerage system.

Let's take a closer look at what can lead to poor flushing and how it manifests itself:

A blockage in the toilet siphon or sewer pipe. In this case, the water will remain in the toilet bowl or drain very slowly.
There is not enough water in the tank. When rinsing, you can even visually see that there is very little water. Sometimes water from the tank does not stop flowing.
The drainage channels in the tank or toilet are clogged. Water flows from the tank slowly, without pressure.
The design of the bowl or drain does not allow for good rinsing.
The enamel covering the inside of the bowl is damaged. In this case, it will be clear that the surface is no longer smooth.
If there is no drain riser in a private house, an air lock forms in the sewer pipe. In this case, the water can leave slowly and evenly or in jerks - at first it stands, and after a while it quickly leaves.
Human waste

The most common and common cause is toilet paper, food thrown down the toilet, cat litter, tampons, foreign objects, or a child's toys getting into the sewer system in the apartment.

Moreover, this may not necessarily happen to you; it is clogged due to the fault of your neighbors, who were not explained that the toilet is not a trash can. The vertical pipe riser becomes clogged, from which various sometimes ridiculous objects are taken out: towels, underpants, etc.

Clogged toilet - common causes

Drainage can become clogged for various reasons. The most common is the penetration of large objects that prevent water from leaving and reduce pipeline capacity.

IT IS IMPORTANT TO KNOW! However, sometimes the cause is incorrect design or faulty system installation technology. As a rule, such malfunctions appear at the very beginning of operation. However, they can also occur after a certain time. Another common problem that causes blockages is the formation of a layer of salt deposits.

If such deposits are not removed in a timely manner, the result will be a gradual decrease in the pipe's capacity, as a result of which it will become clogged. In most cases, finding the location of the plug is quite difficult.

If the blockage was caused by errors made during the installation of the pipeline, it will most likely not be possible to quickly eliminate them. Quite often, blockages appear as a result of sagging pipes where liquid can stagnate, freezing of the liquid inside, or the use of poor quality fasteners.

Another common cause is improper system design, which causes water to stagnate at turning sections of the pipeline. Failure to comply with the slope characteristics also quite often results in a situation where the toilet becomes clogged.

To avoid such problems, you should follow the operating rules. You can only flush toilet paper down the toilet; it dissolves in water. All other items are prohibited from being lowered.

ADVICE! It is also not recommended to flush fat left over after cooking and used tea leaves into the toilet, because... These substances can lead to the formation of a fatty layer, as a result of which the sewer can become clogged.

Chemical method

This method helps with clogs caused by large amounts of organic matter getting into the toilet. Chemical solutions for clearing blockages usually contain alkali, which dissolves organic waste, forming a loose sediment. This work must be done carefully, avoiding contact of alkali on the skin and eyes. Liquid products are poured into the toilet, dry products are poured out and, if there is no water in the toilet, add it in the amount indicated on the package. After some time, the clog dissolves and the water drains away. Alkali is not dangerous for cast iron and plastic pipes; if the pipes are steel, it must be used carefully. There are also acid-based products; they can only be used for plastic pipes. A one-time cleaning with special means does not always help; after a while it can be repeated, or you can combine the chemical method with the mechanical one.
