Completely solve the sewer blockage on the second floor

If the sewer on the second floor is completely blocked, then we'll find a way to solve it.

The best solution on the second floor is overflow pipe+check valve+anti-overflow floor drain, which not only solves the problem that water can't enter the house, but also solves the problem of ceiling.

1. It is best to add overflow pipes to the main pipeline, but the general property will not agree. However, it is recommended to install an overflow pipe at home, directly out of the wall for 30-40CM, and install a check valve similar to a flue outside. Simple and direct, the property will not care too much, but it is best not to lead it down to the first floor for greening. The pipeline is too obvious, and the property may interfere.

2. Check valves and anti-overflow floor drains are still needed at home. In case the overflow pipe is blocked, at least water can't enter the house.

Kitchen: The probability of backflow is the highest, Hammond check valve package+submarine sewer pipe (with check valve)+overflow pipe (hole)+backflow prevention floor drain.

Toilet: special check valve for washbasin+backflow prevention floor drain+special flange for toilet (with overflow prevention function)+overflow pipe (emergency floor drain). The electric toilet is not recommended for everyone, and the later maintenance cost is high, and the blocking probability is too low, so it is not worth it.

Balcony: The washing machine is specially used for launching, anti-overflow floor drain, overflow branch pipe or swimming pool floor drain. If you don't use the washing machine, it's best to seal the floor drain, and the rainstorm is easy to flow back.

Rebellion can only mean winning the prize. After all, the probability is not high. Don't be anxious and don't demonize too much. If you don't take precautions, you have to take a chance.
