HI, I been running into TPR extensions installed using compression fitting instead of soldering the joints
Anyone know how the compression fitting will hold up if TPR valve opens up? Any body else finding this and are you writing it up. Copper pipe installed
Thanks

What type of material is the T&P relief valve discharge pipe?

Any photos?

I doubt that the code specifically comments on this. Since the fittings are approved (I assume) and copper is approved I think it is fine. Once the valve opens the actual pressure that can develop in the discharge pipe is not very high.

Hard to tell from the slightly out of focus photo, but at least some of those copper fittings appear to be SharkBite fittings, which are not compression fittings.

The fittings are likely okay, but several other things are not.

Jerry,

What is wrong exactly....could it be the number of elbows?

I did a quick research to see but did not actually find anything pertaining to the number of elbows.

The problem with shark bites (if that is what they are---they look a bit like pre-soldered fittings) is that they reduce the inside diameter of the pipe two times per fitting (to less that full 3/4") and manufacturer of the valve limits the number of elbows (or equivalent) to four.

Pretty obviously copper, 3/4 in from the picture. Since the drain is not (and should never be) under pressure, I don't see a problem.
