The roof of the toilet downstairs is leaking, and why is the pipe still seeping?

First of all, it is necessary to analyze the specific cause of water leakage, and only when the cause analysis is correct can there be a correct solution. 1. Look at the location of the flat roof leakage on the 2nd floor, if there is a leak at 1 point, whether the people below have drilled the hole with an electric hammer, if so, you have to find him in turn, he may have broken through the floor of your house. 2. Whether the floor drain in your bathroom has been blocked, and the ground has been soaked in water, if so, there will be water seepage in the place where the floor slab is not dense, or the boom hole drilled in the ceiling below (the screw hole is drilled deep) will also leak.

Water seeps through the cracks in the floor tiles into the dry mortar under the floor tiles, so that there will be no water on the floor without water accumulation. 3. See if it is a leak at the maintenance port of the water trap under the downspout of your home, as long as it is replaced, it will not leak in the future. There is generally no problem with the floor drain, and there is no need to change it.

Well, I hope it helps.

Reasons for the leakage of the toilet roof downstairs:

1.It may be due to rust and corrosion of the pipes located at the joints of the pipes and floor slabs;

2.It may be that the waterproof layer on the upper floor is aging and not waterproof.

Recommendations:1If the waterproof layer upstairs is aging, you can negotiate with the upstairs to redo the waterproofing;

2.If the pipe is re-routed and the pipe is still leaking, you can find the community property to help repair it.

The two possibilities you said exist, so first observe the situation, see whether the leakage phenomenon continues or leaks when using water, do not need to leak, do not do engineering, and provide free professional and technical advice on concrete waterproof leakage water repair, so as to avoid the trouble of repairing today, leaking tomorrow, repairing every year, and leaking every year.

The water that leaked before didn't dry up, so it will return to moisture, and it will be fine after a while.

The cause of the leakage has not been found, and there are three analysis points at the leakage point, the waterproof layer, the upper water pipe, and the lower water pipe. There is also a serious or mitigated leakage now than before.
