The other day I saw a first (for me). The home had been a rehab (sort of). The guy replaced all the plumbing. For the hot water he used CPVC which was fine. But for the cold he used PVC. I didn’t make an issue out of it, but what is the official word on PVC being used for the cold water supply?
For what its worth, this is what I put in the report…
Observed the cold water pipes in the home are plumbed with PVC piping. In most cases, CPVC is used on all clean water pipes, and PVC is reserved for waste pipes. While this will likely not cause any serious concerns as this is only used on the cold water side, any future plumbing work should be done in consideration of this. It would be very easy for someone to accidentally connect a waste pipe to this supply piping in ignorance.
