About leaking water in the bathroom

In the case of second-hand housing, there will be some problems if it takes a long time.

I think you can check it, first go downstairs to see if they have an aluminum gusset ceiling in the bathroom, if so, disassemble the plate under the toilet sewer pipe to see, it may be that the lid on the sewer pipe has been leaking for a long time.

If not, ask them to clean the bathroom and find the water from the floor stall, and if they have tiles, spread some toilet paper around it, and then they will know where the water is coming from.

If it is a problem with the water and sewer pipes, go directly to the property.

Since your home is using open pipes, even if there is a leakage problem, it should be visible, please carefully check whether there is a hidden water pipe, or directly find a plumber master to do a pressure test, so that you can find out whether it is a leak on the water pipe.

Also, is there any water seepage in your home's drainage pipes? Drainage pipes include drains, basins, etc. And these drainage pipes can generally be seen from the top of the bathroom downstairs.

It doesn't seem to have anything to do with your family.

Sounds like there's a problem with the plumbing in my own house downstairs.

You go upstairs to see if the sewer seal is not done properly (the sewer outlet where the bathroom floor is cleaned of water).

Method 1: If the waterproof layer is leaking, remove the original tile and clean the base surface. After the cement mortar is proportioned, the ground is leveled and further waterproofed. The height of the waterproof wall is controlled at about 30cm, and the wall is waterproof to better prevent the toilet from leaking.

Method 2: If the bathroom is leaking water from the waterproof layer, there is no need to plane the tiles, just use a new type of penetrating waterproofing agent to do waterproofing on the surface of the bathroom, so that the water does not enter the ground and flows directly from the waterway.

Method 3: If it is a problem with the upper and lower water pipes, and the water pipes are underground, you need to consider planing tiles, but you do not have to renovate the bathroom. For example, if the inlet pipe is leaking, the pipe can be changed to avoid the leaking water pipe. If it is a leak in the sewer pipe, it is also necessary to find the specific location of the leakage, and according to the situation, it is determined that it is partially planed bricks to solve, and it is not necessary to plane all of them.

Method 4, the bathroom is relatively damp, the bathroom will often be surrounded by water vapor, toilet leakage maintenance can consider replacing the ceiling with a waterproof PVC gusset, installed on the keel to cover the pipe. The pressure of the ceiling when the bathroom leaks is also huge, and it is also necessary to do a good job of moisture-proof ceiling.

Method 5, for the ground safety pipe, hot and cold water pipe leakage, should first plane the floor tiles, find the joints of the water pipe, seal the treatment, if the water pipe itself cracks, need to replace the water pipe, after the treatment of the water pipe to re-bury, repair the waterproof layer within the range, restore the floor tiles.

After the bathroom leakage repair is done, don't forget the waterproof test, seal the sewer pipe and floor drain, release the water and then record the water level height, after 24 hours if the water level does not drop significantly, then the bathroom leakage problem is completely solved.
