The slip joint where my PVC sink trap enters the copper drain stack
is STILL leaking.

I've been to the plumbing supply, Mom&Pop's Hardware, Ace, Home
Depot, and Lowes. NOBODY has heard of a "special" slip joint nut
and washer for a copper fitting.

They keep sending me home with exactly what I already have. New
trap parts, nuts and washers slow the leak to varying degrees, but
never stop it.

The water is CLEARLY coming out between the washer and the PVC trap
pipe.

Should I just slather some liquid pipe dope on the PVC, stuff it
into the copper, nut it up, and be done with it?

If that doesn't work I'm going to wrap it with Mighty Fix-it tape
and give up.

Are you sure the washer is the correct size? Seen b/4 where someone
complained about a problem. Here it was an 1-1/4" ptrap, going into
a 1-1/2" drain, there is a special reducing washer for this
application. If you are positive you have the correct sizes, an
unorthodox way is to smear silicone and hand tighten.




What Joe is referring to:

Yes and note the sizes:

•Inlet: 1 1/2"
•Outlet: 1 1/4"

That explains why I grabbed a wrong size washer from my plumbing
stash.... the washer leaked even after changing one out. Silly me.

This is getting scarey. Replies on plumbing from me that actually
contribute.
