After the bathroom is waterproofed, the water does not leak, but the decoration is good and the wate

After the bathroom is waterproofed, it does not leak, but it leaks again after decoration 。Because there may be tiles or something behind the waterproofing, any mistake may lead to water leakage.

After the renovation, the bathroom leakage was found, and the water leakage at this time, we should consider two aspectsOne is the leakage caused by the waterproof problem in the bathroom, and the other is the leakage of the pipe in the bathroom.

The first thing we need to do is troubleshoot a leak in the restroom caused by a leaky pipe 。There are two parts of the pipe leakage: one is the leakage of the water supply pipe, and the other is the leakage of the heating pipe.

The detection method for leaks in both pipes is the same, and we need to suppress the pipes to detect whether they are leaking. Some of the specific operations are: disconnect or close the connection to the outdoor main pipe, and then use the press machine to suppress, we need to hit the pressure to megapascals, and then stabilize the pressure for 30 minutes.

After the pressure drops, make up the pressure to MPa, wait for 30 minutes and then observe, if you find that the pressure drop value is less than MPa, then it means that the pipeline is not leaking: if the pressure drop value is greater than MPa, then it means that the pipeline is leaking.

If the pipe does not leak, then it can be concluded that it is the problem of waterproofing in the bathroom 。So why does there leak after renovation? In the past, the home miscellaneous altar has told you that after the bathroom is paved with tiles, a closed water test will be carried out, the purpose is to prevent damage to the waterproof layer during the construction of tiles, so at this time the decoration company is required to enter the closed water again, if it is unqualified, let them rework in time, so as not to leave hidden dangers for themselves.

Causes of leakage in the waterproof layer of the bathroom.

It's still not done, you have to knock off the tiles again, don't be too troublesome.

It is very likely that it was not done well when it was first renovated, and this will not work.

The amount of water tested is relatively low, and a large amount of water may exceed its waterproof amount after decoration.

If the decoration is good and there is water leakage, it may be that the cracks are not waterproof.

After the decoration is completed, it may be that the waterproof work is not done well, and the master can redo it.

It may be that there is not enough time to check for water leakage, but after use, water leakage accumulation will be discovered over time.

When I tested the water, the amount of water was small, and the small gaps leaked after the decoration.
