Firstly, How To Determine The Toilet Leak?
Generally, there are two reasons for water leakage in toilets, one is water seepage caused by broken water pipes, and the other is water seepage on the ground/floor surface.
1. Judgment of pipe seepage
Pipeline leakage refers to leakage caused by defects such as damage to the upper and lower water pipes, floor drains, and toilet interfaces. The inspection methods are as follows:
(a) Water pipe leakage
The performance of this situation is that the leakage is continuous and uninterrupted, and sometimes the leakage is also increasing. If the main valve of the water pipe is closed, the leakage will be reduced immediately.
(b) Leakage of sewer pipe
Observe the leakage and make a record, and then turn on all faucets and toilets to flush repeatedly and pour water into the floor drain. If the leakage increases at this time, it means that the pipeline is damaged and leaking.
(c) Leakage test method of toilet water pipe
(I) Check whether the water inlet pipe is leaking or not: Write down the data of the water meter. Do not use any water upstairs at this time; check it again after two or three hours; if the water inlet pipe leaks, it must be reflected on the water meter.
(II) Test whether the drain pipe is leaking: Turn off the sluice, and drain all the places where there may be water.; Find a pipe to flush the floor drain. Hold for a long time to see if there is water leakage downstairs. (Note: Do not allow any water to flow outside the floor drain at this time, so that you can accurately test whether there is a leak in the drain pipe)
(III) Water leakage test of the waterproof layer: close all the sluices; drain all the water in the pipes; do a closed water test upstairs for 24-48 hours to see if there will be water leakage downstairs.
2. Leakage on the leaking surface of the toilet
There are two identification methods for leaking surface leakage in toilets, the specific identification methods are as follows:
(a) Leakage occurs only under conditions such as bathing and mopping, that is, when water splashes or accumulates on the ground and walls. In this case, it can be determined as surface leakage.
(b) Use the method of inspection and identification of pipeline leakage to conduct inspection. If it is determined that it is not a pipeline leakage, it is a surface leakage.
Secondly, Repair Methods For Toilet Leaks
If the pipe is leaking, you can only smash the tiles, change the pipe, and re-waterproof.
If it is water seepage on the toilet surface, you can use the following methods to repair:
1. Clean the surface of dust, oil, water, etc., and keep the surface dry;
2. For weak links such as corners, wall edges, pipe roots, etc., use QL- 2 in 1 Reinforced Waterproof Coating;
3. Apply penetrating waterproof glue (such as Qinglong No. 3) on the entire surface that can be exposed to water, such as: tile surface, tile joints, wall joints, pipe roots, etc., and do not miss the brush.
Note: After the completion of the waterproof construction, the waterproof layer must be completely dry (usually after 48 hours) before being exposed to water. Make sure that the base surface is completely dry before brushing. If there is moisture, use a hair dryer to dry it.
