Why do you have to use H pipe fittings, now the pipeline wells have to be comprehensively arranged, all hope that the pipeline will occupy the smallest space under the condition of meeting the maintenance and use, H pipe fittings can be replaced by tee and short pipe, and the pipeline layout is more flexible and convenient for construction. >>>More
PVC drainage is generally divided into toilet drain and wash basin drainage, toilet drain is generally 110 pipe, floor drain and wash basin is generally 50 pipe, sometimes 75 pipe, PPR water supply is generally 25 pipe, if it is heating, it is generally 35 pipe.
Basically, after pasting the bricks, the hole spacing is about 22, then when you buy the toilet, you can choose the hole spacing in 20-25cm, if it really doesn't work, you have to ask the mud master to install a hole spacing shifter, but this will affect the flushing effect, so you should think clearly.
Not more than 3 meters, generally one layer.
The 110 pipe is discharged as a main pipe. The 75 tube is used as a floor drain mop pool. 50 is good to use at the basin.
