It is recommended not to share, but if there is no way to avoid it, it is necessary to install a water storage elbow on the sewer pipe of the toilet, and add a water storage elbow when other sewer pipes are connected, and it is best to install an elbow on each sewer pipe to prevent the toilet from smelling back.

It depends on the upstream and downstream of the sewer, as well as your waste.

Generally not, the pipeline has a return water treatment, that is, there will be a section of elbow in the middle, and the smell will be separated by the water in the elbow, and there will be no smell.
-
If you use a range hood at home, it will smell bad!

Fitted with a U-tube, it's fine.

No, that's how drainage designs are designed today.

As long as it's not blocked, it's generally fine.
The washbasin and squatting sink in the bathroom share a sewer pipe, and the water from the washbasin is directly connected to the urinal.
If the hose below is blocked, you can unscrew it down and dredge it by yourself, if the pipe through the floor is blocked, it is best to find a slightly thicker steel wire or wire, and let it bend it at the end to facilitate hanging and stirring, and then stretch into the pipe to the blocked place and then turn the wire or wire hard, while poking the point up and down, and slowly it will pass, generally near the elbow below
According to the engineering design, 50PVC pipes should be used, if the conditions do not allow 32 pipes, it can also be just not too long, but also to avoid clogging. The sewer connection is also a bit more troublesome.
It should be isolated between the shower area and the toilet and washbasin, so as not to fill the entire bathroom with too much humid air.
