Question:

Is it okay to use a pvc or plastic pipe for hot water pipes in the house instead of copper?

We have a hot water leak in the house that could lead to break the floor slab for repairs. The plummer plans to reroute the hot water pipe to pass through the ceiling instead on the floor but suggested to use pvc or plastic pipe? He said he's been doing it for about 6 yrs and encounter no problem? What's your idea?

Pvc Pipe For Hot Water
PVC is not supposed to be used for any domestic hot water system where you have a water temperature of at least 120 degrees F and a pressure of at least 65 PSI. And actually the working pressure of the PVC pipe at say 140 F (for a commercial application) will go down dramatically to between 48 and 80 psi depending on what site you are looking at. But the bottom line is that it is not safe or practical to use in any domestic application where pressures can run between 45 and 95 psi.
