cpvc plumbing

24 hours!!! no wonder you would want copper, who wants to wait a day after a cpvc repair to use the water. i am not sure anyone but new construction kept to that, just like i am sure very few wait two hours, at least people doing a quick repair to get back up and running. 15 mins is easy by the time you get out or put back what your doing 15-30 mins have passed.

I usually take a break, have a smoke, and turn the water on. Extremely rare any problems with this method. Now if I cleaned up and put my tools away, sure enough something will go wrong lol

newbury/woodlandfarms, Thanks for the responses. Not much difference in price of pipe. I had picked up from the thread about fixtures and tools (especially for PEX), but, the reason I asked, it seems that the cpvc only comes in short lengths, which means many more joints (possible future problems) and so the end cost of more joints v crimping tool etc of PEX might equal out.

Also having to make arrangements not to have a join on the small radius actual loops of a system using short lengths of cpvc would lead to a lot of waste and extra joints if cpvc is used - unless I am missing something.

My proposed use would be an underfloor heating system with water temperature much lower than a domestic HWS. If I go further I would start a new thread and not go OT on this one. I am purely interested in total cost comparisons of cpvc v PEX for any project. I know the OP did not ask the specific question, but I think a comparison is still more or less on topic.

I would use PEX, PEX and/or PEX. You will want the "oxygen barrier" PEX if its a closed system.

I just ran 100 feet of 1" pex gas line. Cost me $59 for the role and $59 each for the two end pieces that are required for the risers. ??? So it was $180 roughly plus tax to run 100 feet of 1 inch pecks gas line before any additional black pipe fittings.

One other note on pex. If you bend, your broke it. You can make it turn tight corners but if you crease the pipe, it is a dead soldier at that point.

If you kink pex, all you have to do is warm it with a torch. It has shape memory and will pop back to its shape

I believe that's only for one of the PEX types (there is A,B,C,...) but I don't remember which one.

I recall only one also has the memory.
