Friends, plastic pipes generally don't corrode in a short time, and there may be two possibilities for your home
1.There is a quality problem with the pipe;
2.There are rats in the sewer near your house.
No problem, it won't seep downstairs.
The floor drain drain has a device that makes the odor not reverse, and it is generally the way to store water in the floor drain bowl, which is called a water seal. The washing machine can be drained temporarily, and it will be restored after washing. If there is a water seal on the drain, it is possible. >>>More
This situation should be dealt with by the property, no matter where it is connected, anyway, it will not seep water, and the neighbors should get along well, don't be a mother, otherwise no one will help you if something happens.
No problem.
As long as the buried water pipe is of good quality, it will be fine if there will be no burst in the middle. >>>More
The black mold and the red color of the liquid are the dust and rust attached to the surface of the evaporator of the internal machine, which is not toxic, but it is very unclean and has many bacteria.
