The toilet drain pipe should be separated, because it will not affect each other if it is plugged all the way, and the toilet will have a smell coming out of the basin pipe, and the general shower underground water woman will bring some hair to be careful and easy to plug and will smell bad, (it is best to separate, and if you don't want to separate, you have to engage in the water bay so that there will be no smell.)
1. There is a lot of water in the bathroom, so there must be a good waterproof layer, and secondly, the water is flushed, and the floor heating effect is not very good. >>>More
It is okay to leave one centimeter or one level with the opposite side, because it is also necessary to install a toilet flange. So you don't need to stay too high, stay too high. Installing the toilet flange will shake and the contact with the ground will not be tight. Under normal circumstances, it is enough to be level with the opposite side.
The height is more than 50 cm, and the exhaust needs to be angled to prevent wind and reversal.
Do a closed water test. It is to put 2-3 cm of water on the bathroom floor, and there is no water leakage downstairs for 24-48 hours. It means that the waterproof is up to standard.
