Used PVC cement for CPVC - ok?
Question:I primed my CPVC pipe with the purple stuff and then used PVC cement instead of CPVC cement. Is this going to be a problem? What is the risk?
Answers:
First off CPVC and PVC are two different chemical make up. And yes One Cement is not intended to work with another. The worst that could happen is that the fitting could fail and flood. One of the differences is that PVC can only handle cold temperatures. CPVC can handle both hot and cold temperatures. Here in Texas PVC pressure pipe is against code inside a building. The best thing to do is cut out that fitting and replace with proper cement.
Yep.
At least you primed it though. That'll buy you time. Maybe years before it falls apart.
I have yet to figure out why it remains legal to use within the building.
If the joint is in an area that cannot be seen, I would change it out with a couplings and a piece of pipe. It is no longer code to use a combination glue that was manufactured for both PVC and CPVC. This should tell you that PVC glue on CPVC will probably not hold.
Cpvc is used generally for water under pressure and higher temperatures...Using the wrong glue on Cpvc is a bad Idea. especially if it used on a water supply system over 40 psi you could have a flood.
