TPRV extention materials

[Frank P. Newman]

Given that the benefit of using PEX is supposed to be labor savings, it would seem to be contradictory to use PEX for this purpose if you have to install an 18" piece of something else and provide additional anchoring anyway.

Copper stubouts at fixtures and the required 18" at water heaters are very common around here when used with PEX.

That's what they do here. Use the copper stubout, install the shut off valve, expansion tank, and copper flex line to the heater.

From yesterday's inspection, copper pipe throughout EXcept this discharge line on a replaced tank. The label says "tighten by hand only".
