Looks like FMC to me and the required disconnect for this appliance is not mentioned, and the time clock, it is a classic case of someone trying to save money!

Where did you find this mess?

Greg,
Regarding your item #2, material not approved for drain line, I checked one particular PEX manufacturers website and see theirs is rated at 100psi @ 180F.

I guess my question is why you feel the material is not approved. I checked my IRC and nothing really was specified other than it must meet the specs in P2904.5 which is the 100/180 mentioned earlier.

Hi Andrew,

I state that because the TPR Valve is set for 150 psi or 210 degrees.

Greg,
I can see that logic. But how does that agree with the IRC? In one section they just refer back to another with lower ratings. I guess CPVC would fall into the same category. But then I see CPVC all the time for TPR drainline.

I did see PEX one time, spoke with my client and he had the builder look into things. Basically for the reason you cited. Plumber came out while I was still there and said they do it all the time.

To follow up with a non interested third party, I asked a plumber and a water heater warranty guy (they were out doing work on my house) and both said it depends on the AHJ. The plumber said they always use copper to avoid any problems. The water heater guy said that if they do a reinstall then they use whatever is currently in place.

Thanks for the clarification.
