Anonymous users2024-01-24A standard toilet drain pipe should be a 110mm diameter pipe.
The pipe of this size should be clear whether it is a sewage pipe used in the toilet, or it may be a pipe used in the toilet, but the size is not standard.
It is necessary to make it clear that waste water, sewage, etc. cannot be discharged together with public pipes.
From a technical point of view, the pressure of the sewer pipe is not large, and it is generally not easy to be damaged. >>>More
Dig a septic tank outdoors near the toilet, one meter square. (The structure of the septic tank: build a partition wall in the middle of the septic tank, and leave a 30X30 cm hole in the middle of the partition wall, so that the partition wall is divided into two septic tanks.) >>>More
WHEN THE SEWER PIPE IS MORE THAN 110MM IN DIAMETER, THERE IS NO PROBLEM WITH A HEIGHT DIFFERENCE OF 30MM, IT IS RECOMMENDED THAT THE FLUSHING TANK SHOULD NOT BE WATER-SAVING, AS IT WILL CAUSE A LOT OF RESIDUE AND FORM A BLOCKAGE AFTER A LONG TIME.
Installing a bend on the sewer pipe can put an end to this phenomenon.
No, the toilet sewer pipes are equipped with U-shaped pipes to prevent odor, and there is a section of water. It is not ventilated.
