There are two reasons for water leakage in general toilets, one is ground seepage, and the other is water pipe rupture seepage.

1, water pipe damage leads to water seepage.

The judgment of pipeline leakage refers to the leakage caused by defects such as damage of upper and lower water pipes, floor drains and toilet interfaces, and the inspection methods are as follows:

(1) The water leakage of the upper water pipe is continuous, and sometimes it is still increasing. For example, if the main valve of the water pipe is closed, the leakage will be reduced immediately.

(2) First, observe the water leakage of the sewer pipe and make records, then turn on all faucets and toilets to flush for many times and pour the water into the floor drain. At this time, if the leakage increases, it means that the pipeline is damaged and leaking.

(3) Test method of water pipe leakage in toilet

① Water leakage test of water inlet pipe: write down the data of water meter, and no water is used upstairs at this time; Check it again after two or three hours; If the water inlet pipe leaks, it will definitely be reflected on the water meter.

② Whether the drainage pipe leaks: Turn off the sluice and drain all the places where there may be water. Find a water pipe to flush the floor drain for a long time to see if there will be water leakage downstairs. (Note: Do not let any water flow out of the floor drain at this time, so as to accurately detect whether the drain pipe leaks. )

③ Water leakage test of waterproof layer: close all sluices; Drain all the water in the water pipe; Do a 24-48-hour closed water test upstairs to see if there is water leakage downstairs.

2, toilet leakage surface leakage:

There are two ways to identify the surface leakage of toilet water leakage, and the specific identification methods are as follows:

(1) Leakage only occurs when taking a bath or mopping the floor, that is, water is sprayed or accumulated on the floor and wall. In this case, it can be determined as surface leakage.

(2) Check the pipeline leakage through inspection and appraisal. If it is judged that it is either pipeline leakage or surface leakage.

Cause analysis of water leakage in toilet

1: There is water on the upper wall near the riser, which may be water leakage upstairs; It may also be that the upper layer leaked water and came down the pipe.

2. There is water on the ground at the lower part near the winding riser, which may be caused by water leakage at the upper part along the pipeline, or there may be problems with the riser, winding joint, valve and cleaning port.

The other walls are watered at the top and bottom of the roof, which must be the reason of the upper floor.

4. The ceiling is flooded, which may be caused by the upstairs, or the pipes in the ceiling of the household (the sewer pipes in the household and upstairs) are leaking.

5. The middle part of the wall is flooded, and the biggest possibility is that the buried pipeline in the wall leaks.

Maintenance method of water leakage in toilet;

If the pipeline leaks, you can only plan the tiles, change the pipeline and re-waterproof it. If there is water seepage on the toilet surface, the following methods can be used for maintenance:

1. Clean the dust, oil stain and accumulated water on the surface and keep the surface dry;

2. Spray penetrating waterproofing agent on the whole surface that can be soaked by water, such as the surface of ceramic tile, the joint of ceramic tile, the joint of wall and the root of pipeline. And spray it without leakage;

3. After the surface of waterproof agent is dried, fill all the joints and damaged and defective parts of ceramic tiles with waterproof paste;

4. For weak links such as corners, walls and pipe roots, Yu Yun plastic steel mud is used for edge sealing and reinforcement.

There are several points to pay attention to in bathroom waterproofing:

Waterproofing at the place where the pipeline passes through the floor and at the junction between the floor and the foot of the wall must be handled carefully. Two waterproof layers are needed in the ground construction of dual-purpose floor drain building with cinder cushion and buried pipe.

Too deep drilling of the expansion bolt in the fixed toilet on the ground (a common phenomenon) will also destroy the waterproof layer and cause leakage. Buried pipes (usually buried first, then the wall is waterproof) must choose high-quality pipes, and there can be no joints.

Prevention and solution?

Prevent water leakage from the source: there are tricks to choose a good water pipe.

Safe water use, from the beginning of the pipe, how to choose a safe and durable water pipe, experts teach you a trick:

Smell: smell the water pipe for any peculiar smell. Parallel pipes are often mixed with recycled toxic plastics, which often have a pungent smell. ?

Second, look: look at the color, thickness and gloss of the water pipe, whether the outer wall of the pipe is marked with trademark, specification, temperature, pressure, production batch number, production date and actual place of origin, and look at the thickness and uniformity of the aluminum layer for aluminum-plastic pipes; Second, see if there is a health permit. Water pipes without hygiene license cannot be used for drinking water pipes.

Three points to note: first, we should pay attention to the fact that regular agency stores have pipe authorization sales books; Second, we should pay attention to whether the purchased pipes and fittings are produced by the same manufacturer; Third, we should pay attention to obtaining product service cards.
