Anonymous users2024-01-24Don't do that, the water pressure impact on the upper floors is very large, in case there is a glass ball or a stone or something, the impact from the top is enough to knock a hole out of the general pipeline, and then another pipe that is re-altered, his joints will not be as strong and stable as the pipe that has been made from the bottom up, in short, it is recommended not to change.

1.The bathroom pipes on the first floor and the risers on the upper floors should not be put together. >>>More
The water supply and drainage design is generally 50-100mm larger than the riser! 150mm is not enough, the maximum is not more than 200mm
This shouldn't be okay, uh, there should be very strict requirements in the high-rise, and it's best not to connect what pipes are used for.
Yes, it is noisy. It should not be used near the dormitory. Hospital wards, nursing homes, should not be used.
There is no such rule, and it is not realistic.
