How is a leaky toilet caused and what to do if the toilet leaks?

The reasons why a flush toilet leaks are as follows:1. The rubber ball valve is broken: once the rubber ball valve is broken, the sealing of the entire water tank is not good, just like there is a hole in the wooden barrel, so the water will continue to flow out.

2. Aging of the rubber gasket of the mixing port: After long-term use, the rubber gasket will become thinner and thinner, and eventually it will be completely aged.

3. The link between the floating ball and the water inlet switch is loose: open the toilet tank, we can see a small ball floating on the water surface, and the small ball is connected to the water inlet with a water pipe, check whether the connection between the two is tight, if it is loose, just tighten the connection.

4. The water tank is damaged by external force: the water tank may be damaged by external force, resulting in water leakage.

Cause of toilet leakage: This is due to cracking and leakage at the interface between the toilet inlet and the sewer pipe. There are three situations in which a small amount of water leakage can occur:

1. The rubber ball valve is broken, the seal is not tight, and there is water leakage, as long as it is replaced. 2. The rubber gasket of the drain port under the ball valve is aging and the sealing is not tight, so it needs to be replaced. 3. The connection between the spherical float of the water tank and the water inlet switch is loose, the float is in place and the switch is not closed, resulting in the water inlet does not stop, and the water flows out from the upright discharge pipe after the water is full, as long as the connection between the float and the water valve switch is tightened.

Toilet leakage repair method: 1. First use a knife to cut the glass glue at the joint between the toilet bowl and the floor tile, and then unscrew the bolts that fix the toilet. 2. Lift the toilet a little, don't pull or push the toilet in place, it will be more troublesome to break the sewer pipe.

3. Then check whether the sewer pipe is cracked, and then connect a section of the same thick PVC pipe, stick it to death with PVC glue, put the toilet on it to try, the length may not be suitable, and then use the saw blade to see until the toilet can be placed stable, and the floor tile is close to the principle. 4. Test the water, no water leakage, glue the base and floor tiles with glass glue, and tighten the screws to fix the toilet. Take over the toilet bowl within three days, don't shake it back and forth, and wait for the glass glue to dry and you'll be fine.

If the toilet is leaking, you can do the following:

Open the water tank, see the water tank is full, water from an overflow pipe, it means that the water inlet group is broken, if you hear that the water tank is for no reason there is a sound of water ingress, that is, the water outlet group is broken, which needs to be repaired or replaced the water inlet group or outlet group.

If the water leaks from the bottom of the toilet bowl after flushing the toilet and is accompanied by a foul smell, then it can be determined that the seal between the drain pipe at the bottom of the toilet and the toilet is not good enough, which requires a new sealant.

In the case of unobstructed drainage, so that the dirt backs up, to deal with this situation, it is necessary to determine whether the drain pipe is not smooth, if it is caused by unobstructed, it is necessary to reinstall the toilet, this situation is generally when the toilet is installed shortly.

1. The water tank is faulty

Damage to the buoy inside the tank, loose connection between the float and the water inlet switch can cause the toilet to leak. You can open the toilet tank and pull the buoy up and down with your hands, **whether the buoy is sensitive. If it's hard to move, there's a problem with the buoy.

Then check the connection between the float of the water tank and the water inlet switch, if the float is in place and the switch is not turned off, it will also cause the toilet to leak.

Solution: If the connection is loose, just tighten it. If the buoy is damaged, the buoy can be removed and cleaned first, and if it is not used normally after cleaning, the buoy can only be replaced.

2. The problem of toilet material

The toilet bowl is made of inferior material or has been used for too long, resulting in cracks in the internal ceramics, which will lead to water seepage in the cracks of the toilet ceramics.

Solution: This situation is completely a problem of the manufacturer, you can directly find the manufacturer to claim for replacement, or you can directly replace a toilet by yourself.

3. The inlet valve is not equipped with a filter

If the inlet valve is not equipped with a filter, the impurities in the water will easily block the small hole of the sealing ring of the toilet tank, resulting in the inlet valve cannot be closed, and the seal will fail to leak.

Solution: After cleaning the seal, install the filter.

4. The toilet seal is aging

The toilet seal is a medium placed between the drain outlet and the toilet drain hole to play the role of sealing, and the aging or damage of the toilet seal will cause the bottom of the toilet to leak.

Solution: Replace the new sealing ring in time, and it is best to put another layer of glass glue around the base to seal it tightly.

5. Improper installation and operation of the toilet

The toilet is not installed properly when it is installed, resulting in the misalignment of the sewage outlet on the ground with the toilet drain diameter, so that there will be water and odor.

Solution: Close the water inlet, reconnect the toilet drain and the sewage pipe, and seal it.

Common causes and methods of toilet tank leakage:

1.The rubber ball valve is broken.

Solution: Once the rubber ball valve is broken, the sealing of the entire tank is not good, just like there is a hole in the barrel, so the water will continue to flow out. In this case, it is very simple, just change to a rubber ball valve that matches the model.

2.The rubber gasket of the drain is aging.

Solution: After long-term use, the rubber gasket will become thinner and thinner, and eventually it will age completely. Once the rubber gasket is aging and the sealing of the tank will deteriorate, the treatment method is to replace it with a new rubber gasket.

1. Causes of toilet leakage

1. Inferior material. In the process of production, it is difficult to avoid that some manufacturers may choose some inferior materials to manufacture in order to save costs, so that inferior materials will cause the water inlet valve outlet and the water inlet pipe itself to crack during injection molding, resulting in sealing failure, and the water in the water tank will flow into the toilet through the overflow pipe of the drain valve"Long flowing water", the phenomenon of water leakage occurs.

2. Improper design. If the water tank accessories interfere with the operation of various mechanisms, it will also easily lead to water leakage. For example, when the water tank is discharged, the float and the float rod will affect the normal reset of the flap, resulting in water leakage; In addition, the float rod is too long, and the float is too large, which causes friction between the water tank wall, affects the free lifting of the float, and leads to seal failure and water leakage.

3. The connections of the drain valve are not tightly sealed. In fact, many times the cause of toilet leakage is caused by the poor sealing of the low tank fitting of the toilet. If the drain valve is not a one-time formed drain valve, and the connection is not tightly sealed, under the action of water pressure, water can easily flow into the toilet through the overflow pipe through the gap of the interface, causing water leakage.

4. Excessive pursuit of miniaturization of water tank accessories. If the tank accessories are too small, it is easy to cause the buoyancy of the float to be insufficient, so when the water submerges the float, the inlet valve still cannot be closed, so the water will continue to flow into the tank, which will eventually lead to excessive water collection, and flow from the overflow pipe into the toilet causing water leakage. This phenomenon is especially noticeable when the tap water pressure is high.

Second, what to do if the toilet leaks

1. The selection of materials should comply with the provisions of the relevant materials in the toilet low water tank accessories standard.

2. The buoyancy of the float (or floating barrel) should be calculated theoretically, at least under pressure, the float can be sealed when it is submerged 3 4.

3. When designing the accessories of the water tank, it is necessary to fully consider the free operation of each mechanism after its installation and not interfere with each other.

4. The material of the drain valve cover should be appropriate, the production should be fine, and the protection during packaging and transportation should be strengthened to avoid deformation.

5. The drain valve body can be formed at one time, and if it cannot be formed at one time, it is best to use the structural form of thread and water-resistant binder assembly at each connection.

6. The lifting water inlet valve should have at least double sealing rings to ensure its sealing performance, and the water inlet valve should be equipped with a filter screen.

Answer reason 1: The inlet valve does not have a filter. If there are too many impurities in the water, it will cause blockage to the sealing ring in the water inlet valve, so that the water inlet valve will not be closed when it is working. Due to the loose sealing of the joint, the water of the non-disposable formed drain valve flows into the toilet through the overflow pipe through the interface gap under the action of water pressure, resulting in water leakage.

If the sealing ring is not tightly matched with the pipe wall, the lifting inlet valve that can change the height freely will often cause reason 3 and the design of the water tank is not good. For example, when the water tank is discharged, the float and the float rod will affect the normal reset of the flap and cause water leakage. In addition, the float rod is too long, and the float is too large, which causes friction between the water tank wall, affects the free lifting of the float, and leads to seal failure and water leakage.

Reason 4: The float in the tank is not buoyant enough. Nowadays, many toilet tanks are small, so that although water can be saved, the buoyancy of the float is not enough, so that the float can not turn off the inlet valve after being flooded, so it leaks. In this case, the float will need to be changed, but before changing, calculate the pressure required by the float, and then choose what kind of float according to this.

Reason 5: Inferior material. Some manufacturers blindly reduce production costs, and choose inferior materials to cause cracking at the outlet of the water inlet valve and the water inlet pipe itself during injection molding, resulting in sealing failure, and the water in the water tank flows into the toilet through the overflow pipe of the drain valve, resulting in "long flowing water".

Cause of water leakage:

1. The problem of water tank material: the material of the water tank is not good or the internal parts of the water tank are old, due to the rapid start of the toilet industry, in the face of the broad market prospects of the toilet, many small manufacturers produce some inferior materials of the toilet tank mixed into the toilet industry, in order to seek more benefits, they choose inferior materials to produce the toilet, this kind of toilet usually does not see its good or bad in the appearance, but there may be some small parts inside, it is easy to be damaged, Of course, it is not excluded that the toilet tank has been used for a long time, and it will also age and deteriorate if it is used for a long time, which is a natural aging process, and the quality of its products is beyond criticism.

2. Toilet sewer pipe problem: The leakage of the flush toilet may also be due to the problem of the sewer pipe below, which is a pipe that mainly connects the toilet tank to transport water, and the possibility here is also very large.

3. The drain valve of the toilet: the drain valve of the toilet is mainly in charge of the water of the toilet tank, generally speaking, in many cases, it may make the toilet drain valve have problems, there may be cracks and deformations in the installation holes, or a series of reasons caused by uneven and uneven installation surfaces and inattentive installation.

How to solve water leakage:

1. First find the location that needs to be waterproofed, see the specific location of the water leakage, and find out the cause of the water leakage.

2. You can make the water pipe buried at the bottom of the tile into an open pipe, it is likely that the water pipe is cracked and leaking, if we cut off the leakage source, there will be no water leakage, so that the waterproof is in place.

3. The bathroom does not smash bricks and waterproof, we can first clean the gaps between the tiles, especially if you can see the cement, you need to clean it up. Then wet the net cement with clean water, and use a brush to brush the cement slurry in the clean gaps, which can be brushed several times.

4. You can use special waterproof products to plug leaks, clean up the gaps in the tiles, use special plugging products, mix them according to the proportion, use brushes to brush in the gaps, and the fastest speed, and then brush several times.

5. The partition can be waterproofed, and the leaking side can be separated by using a glass door to make a partition, so that the water we usually use can not flow to the leaking side, which has a good effect.

1. Causes of toilet leakage:1. The internal parts of the water tank are aging; 2. Water leakage at the connection between the toilet and the sewer pipe;

3. There is a problem with the water inlet group or outlet group of the toilet; 4. The toilet itself has cracks and leaks;

Second, the toilet leakage treatment method:1. If it is a problem with the toilet tank, the toilet tank should be separated and checked one by one to confirm that the water parts inside the tank are installed correctly and tightly. It can be closed with glass glue at the bottom of the water inlet and the junction of the water tank.

The bottom of the flush part is also treated. If the tank parts are damaged, you should buy a new one for replacement.

2. How to repair the toilet leakage caused by leakage at the connection between the toilet and the sewer pipe? At this time, it is necessary to reinstall the toilet, first open the toilet, check whether the internal sewer pipe connection is damaged, be sure to repair or replace it first, and then install a new flange ring, and then install the toilet back and re-seal.

The toilet is an important bathroom product in our bathroom, which not only facilitates our daily life, but also makes the bathroom look more hygienic and clean. The frequency of use is relatively high, there will be frequent leaks, people don't know how to deal with it, I will let you see the cause of the toilet leakage? How to deal with a leaky toilet?

1. Why does the toilet leak - small tank accessories.

Some friends like to miniaturize the toilet tank when they choose the toilet, so they will use the float buoyancy is not enough, especially when the tap water pressure is high, when the water does not pass the float, the water inlet valve can not be closed, resulting in the water constantly flowing into the water tank, from the overflow pipe into the toilet, resulting in water leakage.

2. Why does the toilet leak - the quality of the toilet itself.

In order to save costs, some manufacturers on the market will choose inferior materials in production. It causes the water inlet valve and water inlet pipe to crack during injection molding, which affects its sealing, so that the water in the water tank overflows into the toilet through the drain valve when used, causing water leakage.

3. Why does the toilet leak - the connections of the drain valve are not tightly sealed.

If it is not a one-time formed drain valve, due to the poor sealing of the joint, under the action of water pressure, water will flow from the gap to the toilet through the overflow pipe, causing water leakage. There is also a lift-type inlet valve that can be changed freely, and if the sealing ring is not tightly matched with the pipe wall, water leakage can also occur.

4. Why does the toilet leak - the water tank accessories interfere with the operation and cause water leakage.

If the waiting float and float rod of the water tank are lowered and affect the reset of the flap, it will cause water leakage. In addition, the float rod is too long and too large, which produces large friction with the water tank wall, which affects the free lifting of the float and will also cause water leakage due to seal failure.

How to deal with a leaky toilet?

1. If the toilet tank is leaking, it is basically a problem with the drain valve, you can look at the rubber plug of the water outlet of the lower tank, whether there is damage or foreign body blockage and causes the toilet to leak. Also see if the water supply pipe in the lower tank is placed correctly.

2. Check whether the connection between the spherical float and the water inlet switch of the water tank is loose, if the float is in place, then see if the switch is not closed, so as long as the connection between the float and the water valve switch is tightened, it is recommended to replace it immediately if the rubber ball valve is damaged or aging and causes water leakage.

3. Check whether the flush switch of the toilet can be reset normally, the plastic flush switch of some flush toilets will occasionally get stuck after being worn for a long time and cannot be restored. It can be reset by repeating the switch a few times. It is also necessary to see whether the rubber gasket of the drain under the ball valve is aged, and if it is aged, it is recommended to replace it in time.
