It s okay to use water at home, but as soon as you put the water downstairs, the kitchen will be bac

The waterproofing of your kitchen may not be done well, and another possibility is that the tiles or walls of your kitchen are damaged, located in the same place as the pipes, and your household water will flow down the pipes to the first floor. Check if there is any damage, and if there is a repair, try it. (We once had a project, the 5th floor leaked and the building was fine, but the first floor leaked badly, and after checking, the tiles were broken, and the water flowed down the pipe to the first floor).

In this case, the main sewer pipe should be blocked, and now go upstairs to notify that the sewer can not be used first (all residents upstairs must be notified), and then go to the property, if the property is not responsible, call to find a professional sewer (at this time, you need to negotiate the cost with the upstairs residents).

It could be that your upstairs residents have a blockage in their sewer pipes. When you go into the water, you come up in reverse.

It's okay to use your own household water on the second floor, but as soon as you put water upstairs, my kitchen will be backwater, can you explain it? My family lives on the second floor, I use my own water, nothing happens, but as soon as the water is released upstairs, my kitchen is flooded, which means that the pipe between your house and theirs is blocked, so it is back to your house.

The leakage of water from the roof downstairs must be a plumbing problem of the upstairs residents, and the upstairs residents should be responsible. >>>More
