I think your largest problem is too-thick (old, perhaps?) cement... although I've never seen such a nasty glop inside any PVC (or CPVC) pipe joint of any size. Nobody seems to have asked whether you ream, as well as deburr, your pipe before glueing... but I cannot think that failure to ream would cause a problem like this.

Its a lot cheaper buying the industrial stuff, which ironically is what the ...

I have tried it in a pinch because I did not want to make the time killing run to the hardware store and the joint blew out two days later, it literally came unglued. You would have thought that it would blow out at initial introduction of pressure, right? No, it ...

This is the standard method of attaching PVC pipe to threaded fittings. More turns and less tape. Pipe threads are tapered, in my experience 1-2 turns past hand tight is not nearly enough (and I generally only use 3 turns of Teflon tape). Make sure that your brass ball valve is not cracked, brass is fairly soft and I have seen the threaded part of brass ...
