I'm using the following fitting to join PVC pipes to the brass valve, my concern is that the recommended 3-8 wraps of teflon tape and finger tight plus 1-2 turns didn't cut it. I end up using about 20 wraps of tape and I probably turn it a bit more using a wrench and now no leaks whatsoever.
Is there a different way to join brass and PVC pipes? This is a permanent installation (I can't even unscrew it without cutting the pipes), can I have any problems with it the way it was done?
