The other is that the gas in the sewer rises and expands, because the waterline is too low, the air pressure reaches a certain level, and the squeeze breaks through, producing bubbles and leaking into the bathroom.
It's a trap, right? Generally, there is no model, it depends on the pit distance of your squatting toilet and whether your squatting toilet can be matched with a water trap. For general bathroom brands, the water trap and the squatting toilet are combined into a squatting toilet with a trap, and there is one model, and there is no model separately.
There is no trap will definitely smell bad, but you can install a silicone anti-odor floor drain, it will be much better!
Yes, but the flow angle is less than 135°
Checkpoints should be set up. >>>More
Erect a ventilator to go up to the house.
Let the decorator see if there is a solution, if not, you may have to change the squatting design of the bathroom.
