Averted a disaster the other night... Went down stairs about 10 pm to do
a load of laundry and noticed a seal had blown on the pressure guage on
my water system in the basement and was pouring what must have been a
gallon every couple minutes.. I must have found it less than ten minutes
in and capped it off before my basement flooded.. it was just one of
those things. If I had not done laundry that night, my house would be
****ed right now...

I have been fighting a new Hayward filter for my spa. This thing seems
to have some oversized 1.5" NPT hubs on it and you can't get a regular
male adapter to seal.
I have cut the plumbing open and replaced it about 5 times so far.
Last time I went with schedule 80 pipe nipples with 1/4" cut off the
end that I could run in a little farther than a regular fitting with
a shoulder on it and that seems to be working.

You could always hire a competent plumber, but, of course, you prefer
tinkering.

I've shared Gregg's problem. I replaced our pool pump last year and
had a heck of a time re-seating the threaded PVC fittings into the
filter housing with no leaks. I don't think the plastic housing used on
the filter is the same type of plastic as the PVC coupling fitting. It
wasn't a huge, squirting leak. It was just weeping. I mentioned it to
the guy we get our pool supplies from and he said I should have just cut
the coupling off and replaced it with a new one. Apparently the threads
distort and really can't be reused successfully.

I was using brand new male adapters (two different brands) and the
shoulder bottomed out before the tapered threads sealed.
No joy with the recommended 3 wraps of teflon tape, 6 wraps or the
paste. I also tried O rings at the shoulders and by the time I got the
fitting tight enough to seat the O ring, the fitting cracked at the
threaded part.

As mentioned in another post, teflon tape is tricky. You have to make
sure you wrap it in the opposite direction that the threads will turn
when tightening the fitting. Otherwise, it will bunch up on itself,
causing irregularities in the seal. The natural tendency is to wrap it
in the wrong direction.
