Don't choose an in-line toilet, choose a squatting toilet with a trap so that there will be no smell. I hope my answer can help you.
Personally, I feel that the squatting toilet is better! I can't pull it out with the toilet!!
The sewer pipe is with a storage bend, choose the one without a water trap, the toilet seat sewer pipe does not go out to play where you need to use the toilet to go out to play, the sewer has a trap, if you choose a toilet with a trap two pure water inlets exist at the same time, the launching speed will be relatively slow in the process of launching, and there will be a bubbling phenomenon, and it will also affect the use.
It's very simple, buy cans of putty (putty) in the building materials market and fill the gaps.
If it is used at home, it is better to use the toilet, if it is a public toilet, it is better to use the squatting toilet, and then it depends on personal habits.
This mainly depends on your own usage habits;
The more high-end ones are the toilets, but the squatting pit is more practical. >>>More
