Bad luck! The watermark at the bathroom door is expanded

1. Let the plumber use a pressure pump to detect whether it is caused by a leak in the water pipe. And recall that there are no water pipes passing through the water seepage location.

2. Haven't you done the waterproof coating on the bathroom floor? If the waterproof coating has been made, it means that the waterproof layer has been destroyed. The only way to repair is to pry up the floor tiles and redo the waterproofing.

If you really can't do it, just make the bathroom waterproof again! It should be that the waterproof layer has been destroyed. The wall is high enough to make a height of 30 cm

There is only one faucet in the bathroom, and the floor is equipped with a floor drain--- digging up the tiles around the floor drain. That is, the sewer, no way, if you don't get it now, it will be even worse to infiltrate the other side of the wall. See if this piece is the wettest.

It's even more troublesome if it's not. You have to knock the corresponding bricks along the water pipe to find the leakage point. It's strange that you didn't test the water after the waterproof layer was done???

Hurry up and get it before the final decoration is finished. Even if the bathroom is smashed and restarted, it's worth it.

Stop work first, turn off the main switch of your own house in the corridor, turn off all the faucets, suppress, find out where the water is leaking, look at all the places where you have walked through the water, where the leaking bricks are opened, repair and re-paste the bricks, and when the leaking places are sticky, you can also use waterproofing agent to mix cement with cement to close it and then stick it on, which is troublesome but will not have problems in the future.
