Toilets and toilets with a floor drain sometimes backwater

Is it a toilet or a floor drain @@?

Toilet backwater: Is your toilet a flush toilet or a squat?

Normally, there is no way to open the cast iron pipe from the middle to add things, and the design of individual old buildings is a separate set of drainage on the bottom floors, and then from a certain floor to the top is another set, so my analysis is that the 5th floor is not a set of drainage with your home, and the 6th floor will appear backwater, which has not been done before, perhaps because the water has been blocked for a long time.

Two suggestions, ask if there is such a situation on the 5th floor, nothing to be embarrassed about, neighbors.

In addition, there should be a wall full of sewer dredging phones in the old corridor, and they are more professional.

My family used to do this before, but my house was caused by the general gambling of the sewers below, and the water was discharged so quickly.

1 Change: Still new.

2 Repair ingenuity.

The back-turning water caused by a clogged sewer generally requires the property department to unclog the sewer pipe. After the sewer pipe is blocked, the drainage speed decreases, and if the lower layer is blocked, the drainage outlet will be turned up layer by layer, so dredging the sewer is the right solution.

Your situation is that the supervisor is a bit blocked.

Your sewer pipe is a cast iron pipe, on which the main pipe is on. Three. Five. There is a checkpoint on the seventh floor.

A user, inside the pipe, installed something? >> It's the fifth floor. You are the first victim.

It was cast iron. Now it is PVC, maybe he inserted the pipe too long and blocked part of the supervisor. So the general rule doesn't work.

Solution; First find out whether the fifth floor has been touched in March. Again.
