Wow...got an education in PVC pipe

Glad to see it. Dad owned a sewer and drain cleaning business in UT in the 70's and we would see a drain in a new house annually that was inspected, passed and yet only going to mud not tied to the sewer at all. It looks like the inspector knows his stuff and is doing his job.
 
I believe roughing up the joint, inner and outer surfaces, with some sort of sand paper is important.

Single most important thing, IMO. I use the sand-screen used for drywall sanding and it works well because it is flexible once used a little and it can be torn into strips of various widths, which are handy for working down inside of the different sizes of fittings. I also like to chamfer the end of the pipe - just a little - more like rounding the outside edge of the pipe. The sand-screen will do that pretty quickly. No special tools needed. Have never had a PVC or CPVC joint leak, to my knowledge, but I don't do that stuff for a living. Just home handyman type work.
 
Thanks again fellas for all these good tips...I have to admit dropping the ball again. When I said I used the cleaner and glue there is some of the problem...after this thread and talking to a few pro's I realize that "cleaner" is one thing "primer" is another. I believed that the "cleaner" was the same or equal to clear primer. It is not, they are definitely two different chemicals that do different things. Cleaner is just that, it cleans the pipe. Primer still should be used and then the glue. Sanding or roughing up the pipe and connector is just as important. When I did all four {clean, sand, prime and glue with a twist} on the last several pipes I had to assemble I had zero leaks. It is nice to know exactly how to do something correctly, now if I could just hit the dead center bullseye with my 629 every shot....Thanks again guys.
 
Lots of good info in this thread. Being a gun forum, I was expecting it to be about spud guns, and hair spray.
