Hello experts, the downstairs residents said that the location of the floor drain in my bathroom is

Based on the current leakage phenomenon described, the possibility of leakage caused by pipe rupture is extremely high.

First of all, it is certain that the floor drain is not tightly sealed around the pipe through the floor slab. Now pry up the 30cm wide floor tiles along the floor drain, first chisel the ground to expose the connection between the floor drain pipe and the sewer pipe, check whether the connection is leaking, and if so, reconnect well; Then open a conical groove with a width of 5cm and a depth of 5com around the floor drain pipe, fill the solid groove with the plugging king or nozzle grouting material after washing, and after the filler is dry (about 2 hours), apply flexible waterproof coating on the pried open ground. Then stop the toilet water for more than 2 days, and then use the water for half an hour to discharge the floor drain, and then check whether there is any leakage downstairs.

If there is no problem it should be solved, then put back the pry up floor tiles.

Close the main valve of the inlet pipe. After removing all the water in the pipeline and no signs of leakage, plug the floor drain and store water on the bathroom floor for 24 hours to check the leakage. If there is no leakage; Close all sanitary water inlet valves in the bathroom. Open the main valve of the inlet pipe and check for leakage, if there is a leak, it is a rupture of the buried pipe in the wall.

If there is no water leakage, there is no problem with burying pipes in the wall. If the test results show that there is water seepage on the walls and floor, then the entire bathroom will have to be redone. When repairing the wall or floor alone, pay attention to the waterproof treatment at the interface.
