I just got a new house, and I recently renovated the bathroom to do a closed water test, but I can t

The following two situations need to be noted in advance:

First, the closed water test is no problem, but water seepage occurs within a few days.

Reason 1: This may be due to the bricklayer in the construction process, due to the early ground leveling or the corner of the wall arc is large, the paving can not fall bricks, in order to facilitate its construction, the protruding part is shoveled off, resulting in water leakage.

Reason 2: When the water and electricity pipes are laid on the ground, the bricklayer tramples on the water and electricity pipelines too seriously during the construction process, which will waterproof and tear the corners, causing water leakage.

Second, the decoration has been almost a year or two, and there has been no water leakage before, and now there is occasional water seepage in the bathroom.

Reason 1: The biggest possibility is that the expansion and settlement of the new building is large, which exceeds the stretch degree of waterproofing, and the waterproof will be torn, resulting in water leakage and water seepage.

Reason 2: The purchased waterproof coating is a counterfeit, and the water resistance and corrosion resistance are not strong, and water leakage and water seepage will occur after a long time.

Reason 3: Sewer pipe displacement, in the case that the sewer pipe displacement must be carried out, in the process of decoration, try to ensure that the sewer pipe is covered and fixed with cement mortar, and ensure that the waterproof coating is painted into a film and cannot be painted on the pipeline.

Yes, you can also declare to the property in advance, and declare with the owner in advance that you have notified him that he will not reply and cooperate, and you will not be responsible for the losses caused.
