Cpvc!?


Wondering - Unless the Authority having jurisdiction says he/she want's to see it, why would anyone use CPVC over PEX?

In my opinion CPVC is garbage. Might as well use PB. PEX is far superior.

Hmmm, let me think.... pex cost? pex tool cost? pex connector cost?
All GREAT reasons for me!

cpvc works fine and costs way less than pex and needs no special crimper tools....
A saw and two cans of primer and glue is all that's needed!

Everyone's entitled to their opinions though!

It works. That is all that matters to most. I know there are new products coming out all the time, and many are quality products. I really hate to see the "plumb" taken out of Plumbing. Looking at Pex runs reminds me of how much I like spaghetti.

I guess I may have a different opinion if I were to live in a different climate. In Idaho we have hot summers and cold winters. The expansion, contraction, freezing, kills pipe. Don't get me wrong, I don't care to see the "Plumb taken out of plumbing" either. I've seen PVC and CPVC however, become so brittle you could crush it in your hand after just a few years. Rarely in my service past did I see PEX burst in freezing weather and don't recall ever seeing it become brittle. Likewise, I've seen major disasters with copper, PVC, CPVC, and Quest (PB). Certainly plastic pipe with glue fittings is simpler for the DIY'er without specialized tools.

Haha I don't think that's legal though is it? I see it all the time done with pex or pvc, but should be copper I think within 18"

Ok, I just looked it up and you're in the clear. According to IAPMO/ANSI 2003 UPC (608.5) Relief valves located inside a building shall be provided with a drain, not smaller than the relief valve outlet, of galvanized steel, hard-drawn copper piping and fittings, CPVC, or listed relief valve drain tube with fittings which will not reduce the internal bore of the pipe or tubing.
