Has anyone else had problems with leaks when you screw a Sch 80 PVC
into a sch 40 (white) fitting? It doesn't seem to matter no tape, the
right amount of tape or a **** load of tape, they leak. You can run
them up until there no threads left and they still leak.
I am not sure if this is a vendor problem or just something that
happens. I am gluing them now.

I have never had a problem with that.

Agree w/ fretwell; one or the other is wrong; by spec they should be
fine (other than the fittings aren't rated for service, but presuming
the leak test isn't above their ratings mechanical fit should be same).

Probably cheap import QA of one or the other; no way to guess which w/o
trying another supply of one or the other.

It's never wise to use a female Sch 40 fitting on a male Sch 80 pipe
end; other way round is safer altho still the fitting itself isn't rated.

Unless, of course, there's really no need for the Sch 80 at all in the
specific service other than perhaps just have on hand; the pressure
rating will never be approached.

I just had it happen 3 times in a row with different fittings. Maybe
the Sch80 stuff is just a little small or something. It is a different
vendor than the Sch40. I am not having the problem with brass and PVC.
Even the cheap stuff they sell in the lawn sprinkler aisle works
better than the Sch80.

This was just the classic, "what they stock locally" and with this
virus thing I didn't want to be driving all over town.
Ace will pick and give it to you in your car, prepaid online.
I really only needed one threaded fitting in the line and I still
ended up with one I didn't have to glue but it did seem strange that
this failed on 3 different joints in 2 sizes (3/4 and 1/2)

I have noticed mold web on the threads on Sch 80 occasionally which
might cause a problem. It might be that running them into a steel
fitting thread or threading tool might clean those up if they cause
problems. Or, buy them somewhere that makes them better.

As I said in the other note, things being what they are, I am not
driving all over town looking for a better source.

Why not? It's just the flu and we shouldn't shut down the economy,
that's what you said here. Sounds like reality is setting in. But
I have to say, you were partly right about Spring Break, with young
adults on the beach. I didn't realize both college kids and your
state govt were so irresponsible. I think many of those areas with
beaches open had bars and clubs, etc closed, I guess that's better
than nothing.

You are just trolling now. I said a week ago I am following the rules,
probably better than you.

BTW these college kids are from the north for the most part and "going
home" is not that easy for them since their tickets are for next week.
