No you shouldn't. It will fail inspection. Use electrical (grey) conduit. It is about the same price and has the proper electrical insulating properties required. The thicker PVC(schedule 40) is best, although schedule 80 is acceptable. (Schedule 40 is required for underground service feeders.)
Not in my house as I am allergic to carcinogenic materials
NO
no
Why not, the Plumbing PVC actually has more testing to meet plumbing standards than PVC conduit. Both are made of the same material, so yes it can.
PVC is commonly used in plumbing
If the local and state building codes allow PVC for plumbing waste and vent then there shouldn't be any legal action.
It depends on the plumbing code in your area.
can you used pvc pipes in a commerical business kitchen
Yes, if it is rigid PVC conduit approved for electrical installations. Don't use PVC water pipe as it will be rejected if inspected.
No! Steel is a very bad choice for plumbing, as it rusts and can poison your water. PVC, copper, or clay pipes are recommended for plumbing.
Depends where you live, going rate for plumbing and what kind of plumber. Most will not use PVC to rough in a house. -( Why are you not using PEX .)
Electrical wiring.
did you mean pcv? if you did mean pvc, then it depends if you want to use it for water or for waste. and if for water, how many bars of pressure will be in the pipe and for waste is underground or not. unless these questions are answered the answer to this question is vast.
The main use is in electrical wiring.
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
Yes, you can. If possible, first prime the PVC with 'purple primer' ( from plumbing supply store) then use PL200 to join the pieces. Clamp them for 3-4 hours for a strong joint.
