Either wrong type of glue or you did your 1/4 turn after the glue started the weld or you let up on the pressure to early. Heavy duty will take longer to weld and needs to be held under pressure longer or the pipe will back out when you let go of it.
I don't do a quarter turn and dont have a problem with my house plumbing that is set at 65 PSI. I cut, scuff, prime, glue, and hold then move on to the next fitting or segment.
I use medium (black oatey can) for white pvc and cpvc cement for cpvc. With CPVC I hold the joint tight for 30 seconds and for the medium glue I hold it tight for 60 seconds.
