What should I do if the water level drops a little before the bathroom is waterproof and closed

Combined with the water seepage situation on the roof of the neighbor's bathroom below, it is best not to fall as much as possible, and Guoerjia Waterproof Company can do it.

At the beginning of the closed water experiment, it is necessary to notify the residents of the lower floor, and there is no need to notify the lower floor; When the water level drops, the first part needs to go to the downstairs residents or the downstairs floor to check whether the top surface of the bathroom is leaking or damp, if not, this item can be ruled out; The second is to check whether the water is lost due to floor drains or sewage pipes that are not blocked; Third, check whether the windows are closed, there is no air flow through, or the weather is very hot and dry, etc., if these reasons are too large, the water will evaporate and the water level will drop.

The bathroom did not do a good job of waterproofing, and in principle, it had to be smashed and redone. There is an economic loss for sure, and it will be higher than the cost of renovating the bathroom for the first time, because the master in the industry would rather take the work of decorating the rough house than taking the work of repair. As for the damage to the structure of the house, as long as the construction is reasonable, the use of electric hammer instead of real hammer will not cause damage to the structure of the house. >>>More

Check if there is a water leak downstairs, if there is no water leakage, it should be caused by evaporation, and it has nothing to do with water leakage!

It depends on whether there is dew downstairs, if there is water seepage, it is not okay, 2 mm is actually nothing, but look at the lower wall.
