The shower was useless for 24 hours and there was no water. Dripping water from the bottom of the fl

Most of the water is drip from the main sewer pipe, and the PVC pipe has poor sound insulation and noise reduction, so you don't need to pay attention to it if you don't find a water leak.

This resolutely does not work, you must wait for the waterproof layer to completely dry, and then carry out a closed water test to ensure that there is no leakage, before you can start tiling, and in the process of tiling, you must ensure that there is no damage to the waterproof layer. The so-called closed water test refers to the toilet waterproof layer is completed and dry, the floor drain on the bathroom floor, the nozzle and other drainable pipes are sealed with tape to ensure that there will be no water leakage, and the water surface of the bathroom begins to release water, the height of the control principle is that the water surface must be higher than the upper mouth surface of the floor drain and must ensure that the floor of the bathroom can be immersed in water, so that you can see whether there is a leakage problem in the bathroom downstairs, and the water storage time is at least 24 hours or more.

That is to say, we also have a temper, I will take care of you when you don't want to deal with me, it's not a restaurant that is open 24 hours a day, you can say whatever you want.

There are many reasons for a drop in water levels, it can be water seepage or a poor sewer seal. Whether the closed water test is qualified mainly depends on whether there is water seepage in the rooms adjacent to the downstairs and bathroom.

Is there a logical relationship between this and water pollution? Water is so precious, aren't you doing it because you're choking on food and wasting it?
