Toilet sewer principle

First of all, you need to determine whether it is the water seepage of the water pipe itself, or the water seepage caused by the subtle cracks between the water pipe wall and the floor, if it is a water pipe leakage, you can choose to change the water pipe, if it is the latter, it can be solved more easily, and the method of testing them can see whether the water of the water pipe is intermittently leaking, intermittent water seepage is more likely to be a crack between the water pipe wall and the floor that causes water seepage, that is, when someone uses water on it, it leaks, I don't know if it is also a bathroom above, When doing waterproofing, you need to do waterproofing on it, you can use the best seam treasure to scrape a layer around the pipe wall, the seam treasure itself has good adhesion and waterproofness, can effectively deal with the problem of water seepage, and what questions can continue to ask me.
