Anonymous users2024-01-24There was a problem with the sewer pipe, and the quality of the drain was not very good. Do you use PVC drainage or something else, Zhengzhou Huida Plastic has a good drainage pipe there, I think you should have to change one.
Did you accidentally pour a fluorescent agent or something?
It could be that the drain trap is leaking. When the trap runs out of water, the water upstairs flows downwards and the drain pipe is pressurized, and when it flows downward, negative pressure is formed (absorbing the bathroom gas) to form a force of increasing or decreasing air pressure, thus making a sound. This is just speculation....Because sound is produced by the vibration of an object, the vibration of an object is produced by an acting force, which is an immutable law.
That's because there is no S elbow installed on the sewer pipe, and the straight pipe will make the smell of the sewer come up through the straight pipe, and you can add an S elbow like the picture, or if the sewer pipe can be bent, bend out a shape, so that the water in the elbow is in the red line, and the odor below will not come up. >>>More
Accumulate a lot, where there is more clutter, there will always be a moment when it is blocked!
It's simple: someone shines a flashlight or other electric light at the entrance of the sewer and refracts it through the entrance of your sewer.
