Seeking advice on following situation. I have a plastic u-tube connecting
the downspout of my kitchen sink, to the next pipe in the sequence.
I have replaced the gasket and applied TFE Paste to the male part of the
tubing that screws in to the female connector, tightened it as tight as I
dare, and yet it still leaks.
Much obliged in advance,
is the problem. Hand tighten snug. All connections at once...bit on this
one, bit on that one, bit more on the ones you already did. If it drips,
tighten a fraction more. You can always make it tighter if you put it too
lose in the first place. Once you overtighten, it leaks because the ring
seal is damaged. Loosening it does no good.
If your trap and piping is plastic and is still leaking, you re using the
wrong gasket or have it in backwards..it should be a tapered plastic ring
(the color of a milk jug) the narrow edge pointing "downstream" . Its made
to work by turning the coupling HAND TIGHT, without ANY teflon tape or
paste. If your "next pipe in sequence" is metal, it would probably be
easier to replace the whole leaking metal set up with plastic than to chase
the leak around . Make note of exactly what you have at the wall, maybe even
take a digital pic of it and go see yer plumbing guy at Lowes or Home depot.
The parts should be under $ 5.00
Sloppy Fix Alert:
They make a 2 part putty for PVC pipe. You mix it together and press it
into the leaky joint. Once it hardens, it seals the leak.
I'll admit that I tried it as a "temporary" fix on the seam of a PVC
trap about a year ago - it worked so well I have yet to replace the

We often look for ways to Band-Aid what we didn't do right in the first
place. I've used dabs of silicone for pin drips. I mean heck, roofing
cement works great for a super hack job.
These connections are typically the slip nut type with a gasket to
seal. Pipe tape, dope, silcone, etc are not required. And IMO,
trying to use silicone to stop where it's leaking is at best a
temporary fix, as the joint is not made up right and is likely to start
leaking again before long, especially is some bumps some thing against
it. If the joint is properly aligned and tightened, it won't leak.
If it leaks, something is wrong. The joints don't need paste.
I had the same problem a couple years ago and just replaced everything. It
was less than $10 and doesn't leak. Unless you have absolutely nothing
better to do, that is a bargain.
