I am having a problem sealing PVC pipe threads--male to female --I use pvc
male adaptors to pvc valves --and more than 50% of the time, the
connection leaks --I have tried pipe dope, rectro-seal, teflon tape, over
tightening, and just barley tightening the fitting (also normal
tightenign) --this is quite annoying since the joint must be redone --and
there is no way of testing it until all is hooked up --any suggestions for
pvc to pvc thread joint leaks??
You also need to make sure the wrapping of the tape is counter-clockwise in
order for the tape to work properly. Otherwise you'll just push the tape out
of the way when you tighten the fitting.
Here's an easy trick to consistently do it right.
Hold the fitting in your left hand with the threaded end facing your right
Start the tape on the top of the thread, from the left side of the thread,
and roll away from you, moving down the outside of the pipe and back up the
inside. If you were to point the end of the pipe away from you, you'd see
that the direction is counter-clockwise.
Keep wrapping in that direction working your way to the end of the pipe
threads. That would be moving from your left to right on the pipe.
Keeping in mind I've had my share of Aw Shits, another tip would be to make
sure the male and female seat is firm, even and flush without you holding
it before you tighten.Trying to correct something misaligned by bending,
twisting, pulling etc then tightening is a prime leak candidate.
I've had pretty good luck with liquid teflon tape as well.
