I only have 50 points in the bathroom downstairs, help me!

It's hard to make a difference, I have a little suggestion you can try, choose a high acid nail or actually a high staining chemistry, and only add one of them.

For example, add it to the toilet bowl to see if there is a color change in the water leakage downstairs, and then try each one separately, and the one that has a color leak is the problem.

At the same time, when these problems have been dealt with and there are no other problems, the buried pipes will be cut and reinstalled, and sometimes a small amount of infiltration cannot be seen with the suppression and leak detection equipment.

I think you'd better find an experienced master to see, the property is not the same people have a lot of experience.

The place I used to rent was also, the roof of the downstairs bathroom was leaking, and the place you said was similar, that is, the waterproofing under the toilet was not done, and it was okay to redo it, and the toilet may not be used for a day or two. You'll see if it's going to be the problem.

It's rare to have a problem with the pipes buried in the ground and on the wall, and you can go downstairs to the ceiling to check the drain pipe The problem should be there, and you can also fill the drain with water to see if there is any reaction downstairs The water should be large.

Although it is correct to use pressure to diagnose which pipe is leaking, it may not be possible to find out if it is a small leak like trachoma for a long time. Your main problem now is which pipe and where the pipe is leaking, right? Seriously, I don't know what a floor drain is.

There is a safer way, but it is more time-consuming. It is to close the valve in front of the pipe that passes through your bathroom, leaving only 1 to use, and then see if there is any leakage downstairs, if there is, then this pipe will definitely not work. Then try another one.

And so on. After determining which pipe or which pipes are the problem, directly pick up the pipe and reconnect the new pipe. (Don't try to mend the sewing in the old pipe, treat the symptoms but not the root cause).

Yes! It's easy to have the landlord say so, scrap all the underground pipes, no need to check for leaks, re-pave the pipes on the ground, two supervisors, one cold and one hot, are in the washbasin fork.
