In response to Re: pvc/cpvc glue
There are cements that are multi-purpose, but they are labeled as such and specify which plastics are included. PVC and CPVC are not really in the same family. I would not worry too much if the joints are outside where they can be accessed. If they are inside the house, the inspector is not your problem. Your problem will be the joints that fail several years down the road and are inside the walls.

: I noticed the "hot" blue pvc cement I used for cementing cpvc fittings does not speicifcally allow nor prohibit it's use on cpvc pipes (the label says "for use on all PVC products", which may or may not mean including cpvc; probably not though).

: Bottom line, if I previously used this glue to make some cpvc connections, should I be concerned ? (yes, purple primer was used first) Would a plumbing inspection/inspector likely pay attention to the color of cement used?

: Have any tests/studies determined the long term effects of using pvc glue on cpvc pipe?
