From that site (useful site, by the way; thanks):
I guess a comparison between the TPR ratings and the in use PVC ratings should be made then before calling them out. All CPVC that I have seen including what is in my house and new construction is rated at 100 psi at 180 degrees F. I just checked a new stick of 1/2" I recently purchased and it is the same rating. I guess the better quality stuff hasn’t made it our way yet. Until then, I’ll keep calling out the lesser rated CPVC and PVC regardless of jurisdiction allowances. I personally don’t feel it’s safe and will at least alert my clients to it. Let them make their own decision.
They are two different materials. I don’t believe they are interchangeable. I have no experience with CPVC. I did read the link above about both PVC and CPVC, so I do now have a little knowledge about CPVC.
Very true and I am guilty of using them interchangibly as are many others.
CPVC is what is used mostly around here for plumbing pruposes. It is very inexpensive and easy to use. I don’t have issue with it’s general use, just use as a TPR drain line.
p.s.
I did’nt intend for you to go get wet on my account.
That is a very good site. Thanks for the referance!
Considering that the TPR drain line typically would only have to take a short burst (five gallons is what I generally hear plumbers use) of high pressure, high temperature water because it has an open end, and because it is sooooooooooo easy to change, the type of material that the TPR drain line is made out of is one of my least concerns. I will always call out unapproved materials, but the TPR drain line doesn’t rank anywhere at all on my list of major concerns that I find during a home inspection, unless it’s currently plugged. The mud wasps like to create homes in the ends of the drain lines here.
What ? !
What? !
I think RR posted that comment, did he not? So excuse me for sticking my nose in here with a comment.
You mean he shouldn’t make any comments that make reference to a Mexican immigrant?
If I read the statement correctly, he said south of the border LICENSED- meaning license obtained south of the border- therefore not acceptable in the northern 48.
If you mean it’s not acceptable to say anything about illegals and their illegal work habits, I don’t see how you can inspect. Do you check to see if it was a Mexican immigrant first, so you can give them a pass for unacceptable work? If people from that country want to come here to the states to work, they should be expected to live up to our laws, customs, and regulations just like all other American citizens do. So they should be expected to get licensed up here, in the appropriate state, just like we who were born here do.
I have a huge problem with Mexican immigrants who come here and refuse to do things properly, just because the money’s easier to find here in the states, and then get testy about it when they’re told they should get legal first. Nobody I know has anything against Mexican people. But we do have a BIG problem with illegal immigration. So if everything someone says is interpreted as knocking all Mexican immigrants, instead of corrrectly interpreting it as a desire to observe our laws, which protect our economy and way of life, then that’s your problem, not mine. The way it read to me, I don’t think his statement was aimed at being derogatory toward Mexicans at all! But then again, I might not have read it right. But if I did, I stand by RR on this one!
