Why is it forbidden to use polyvinyl chloride fibre glass pipes as wire conduits and buried in the floor?
PVC20 pipes are usually used. If you wear two wires, use 16. You need a bow, a few lines, and a 20 spring, you can bend it to 90 degrees.
After completion of the project, use 1 or 1.2 steel wire through the box, use the PVC86 type nut, use 20 glue, and use PVC glue. Double commissure, box 146.
