P-trap slip joint still leaking

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.

I would go buy one of these (either 1 1/2 or 2" depending on your
currnet fitting) and try the nut that comes with it.

I bought one of these at HD a few months ago and the nut had an
integrated washer that pressed against the inside flare of the copper
fitting and pressed tight to the inserted PVC. No plastic cone washer
or rubber washer. Worked great.

I had a cone washer leaking, so I grabbed one from my plumbing stash.
It leaked also. Apparently there are different sizes?

Why not? Three-ply duct tape works wonders on top of the roofing tar.

Obviously, you either need a smaller diameter washer or a larger diameter
pipe. Maybe you'll have to change it out unless you can seal it with the
other suggestions. It may be just as easy to swap the pip, but I can't see
it so can't say for sure.

I'm hearing some faint bells go off here. I had a similar leak until I
(a) pointed the damn washer in the other direction and (b) went out and
bought a metal nut, rather than the plastic one that came with the trap,
to hold the tailpiece into the metal pipe coming out of the wall. Not
sure if that applies to OP's situation, but unless he already threw out
the old parts, it doesn't cost anything to try.

Unless it's a new installation (within the last couple of years) I now throw
away the washers and plastic nuts and use new ones. These things are cheap
and are often damaged in a way that's not obvious.

The problem is those P traps are junk quality:(

I havent had a leak in years since I started putting silicone caulk on
the fittings right before putting them together.

The bathtub caulk is cheap, stops any leaks:) and the fittings still
come apart easily when necessary:)

I think I finally got it. Running the dishwasher right now, and no
drips!

It took FIVE different nuts and washers to find one that would seal
up. The one that finally worked was from Lowes, a metal nut with a
super-soft orange washer.

I tried the plastic nut with plastic washer from the kit, metal nuts
with tapered rubber washers in each direction, metal nut with square
rubber washer... all leaked.

Sounds like you have a damaged part in there. Leave it, as long as there are
no leaks, but next time you go in there, replace everything. It's cheaper
than insanity.

I bought a kit.

The kit does NOT come with:
1. A nut and washer for the drain stack.
2. Tailpiece for the sink drain basket.
3. Nut and washer for the tailpiece.

That's the thing. I DID replace everything that was replaceable.
TWICE.

BTW, it still leaks. Only one drop every time the sump pump runs,
which is a HUGE improvement over a tablespoon. Luckily the sump pump
only runs when the laundry machine drains. Once a week.

I'm going to let it go a while. Hopefully with some crud and mineral
deposits it will seal up.

You probably have the same problem I frequently encounter. You are
attaching a metal tailpiece to a pvc ptrap and the hard plastic beveled
washer is still allowing a small amount of water to leak through and come
out around the plastic nut. Go to Lowes or Home Depot and buy a rubber
washer designed to go into the nut for a metal nut fitting. You put the
nut plastic ptrap nut on first, then the soft rubber washer and finally
the hard plastic beveled washer. When you tighten down the nut, it will
cause the soft rubber washer to compress against that hard plastic washer
and form a much more watertight connection around the metal tailpiece and
plastic nut. I think the issue is those plastic washers are so hard they
don\'t compress well around the metal tailpiece. The soft rubber washer
will, and the extra benefit is you can tighten the plastic nut without
cracking the plastic washer if you happen to over tighten the nut. The
rubber washer ( orange at Lowes ) is about 25 to 50 cents. Well worth the
aggravation.

leaks like these are why i use bathtub silicone sealer on the joints,
its cheap, easily removable in the future, and ends all leaks.

clean and dry all connections totally, let parts sit to dry or use a
hairdryer or heat gun so no moisture remains!

Then butter up the pieces and assemble, let dry a hour or so and dont
overtighten fittings which are really cheap junk quality to begin
with, and can distort if over tightened.

end of leaks forever:)

When I had the same problem, I used a metal nut instead of the plastic
one, along with the rubber washer instead of the plastic one, and it
stopped leaking.

If I ever get rich enough to build a house, I'm gonna run the drains
through the floor, instead of the wall. In my experience, that hard-90
right inside the wall is where the hairballs and soap gunk love to hold
on for dear life. When the binary drain cleaners won't clear a slow or
clogged bathroom drain, running a 12" bottle brush into the hole on
wall, as far as it will reach around the corner, almost always clears
things right up.

the silicone caulk has never caused a problem, I just use enough to
seal small openings not big gobs.

besides if you ever have a problem its very easily removable and
doesnt weld the joints or anything like that.

A plumber did that here once after I was unable to seal a joint, I
stole his idea:)
