Anonymous users2024-01-23Install a one-way water stop valve, there is no other way, Taobao can buy it.
The advantage is that there will be no backwater, but the speed of launching will be slower.
I am also worried about the problem of backwater, and I have been studying this matter for a long time, and the installation of independent pipeline properties may not be given, so only this method can solve it.

Anonymous users2024-01-22The reason for the toilet backwater is more because the drop position of the main pipeline to the drainage channel is low, and the air pressure can be solved by opening an upward exhaust hole at the top of the main pipeline at any time, and there is no need to install a check valve.
How to block the water without backlash:
The sewer is blocked, tell the neighbor not to pour the water kitchen, find someone to dredge, the first floor of the current building is a single drain, the second floor will become the former first floor, so it is easy to block, dredge it will be fine, completely solve unless the pipe is alone, but it is very troublesome. >>>More
It is estimated that the sewer supervisor has a partial blockage near your home, and it is not blocked. >>>More
The property should be responsible for the damage caused by the failure to repair the property in time. Therefore, when we find out what should be repaired, we should notify the property in time and leave some evidence, so that if there is a problem, the property will bear a lot of responsibility. >>>More
This situation should be blocked somewhere between the second floor and the first floor.
That's going to have to talk to the property and the ground floor about that.
