Do any other plumbers here use pex tubing to connect a water heaters T&P valve to copper drain lines that lead to the exterior of the building? I'm a service plumber and do it on a regular basis without thinking twice about it being a code violation. But recently someone brought it to my attention that it might be in violation of 608.5. My code book dates back to 1994 and does not mention pex tubing. What do you guys think? violation or not?
No announcement yet.
Pex tubing used for T&P Drain. Is it legal?
