The kitchen sink pipe drips a drop per hour. We'd called the plumber
over and he replaced the sink funnel and drain pipe. It still drips.
I noticed he put some gasket glue. But it appears to be leaking at
the same area which is at the neck of the funnel (right below the
bottom of the sink.) What could I do to solve this problem without
calling the plumber.
I am not totally sure what the problem is, but off hand it does sound
like the plumber did not find the real problem or he did not fix it. Give
him a call. Tell him what is going on. Assuming he did not say something
like "The work I did should fix it, but you really need to ......" and you
did not do as he suggested, he may offer to come out and make his work good
without charging. If he does, then make sure you keep his name and phone
number handy for yourself and anyone who may ask you if you know a good
plumber. He he does not want to cut you a deal, then, assuming there is
nothing about this you did not tell us, then consider the cost a learning
experience and start asking around for the name of a good plumber.
From your description, it may be the sink itself or a problem with one
of the fittings of the U shaped pipe. That may be fixable by tightening the
large nuts or replacing the washers and re-installing
You might want to stop by your local hardware store and pick up one of
their DIY books for the homeowner. This kind of thing is difficult to
explain without photos.
sink funnel = sink strainer ?
he might not have tightened it enough. Try to tighten it. He should have
used plumbers putty to make the seal with the bottom of sink. It is like
play-dough kinda. This is an easy repair unless your sink is rotted. This
is grounds for a free call back with me. I would not dream of charging you
for this and would be very apologetic.

The leak is from the bottom part of sink strainer that goes into a compression
coupling on the "drain pipe," after a closer examination. This (compression
coupling) is very tight as it can't be hand twisted any further. I may wiggle
the drain pipe (with my pinky) while someone is washing dishes and it will
begin to drip faster. The strainer appears correctly installed with the
doe" formula. The leak is coming from the compression coupling, as you
call it, and I can collect half a cup while washing dishes. If I put silicone
caulk then I might run into trouble the next time I remove the pipe. If silicone
caulk is a good idea, I might try silicone caulk. Or ask the plumber to come
back, if it's not out of line.
I thought I had the same problem at the compression joint. I was *wrong*
Turns out that the drop tube (connected to the drain with threads and then
you connect the p trap to it) has threads that screw into the drain (threads
on the top of this pipe). Those threads needed a turn of teflon tape and
the dripping went away. the leak was so subtle that I too thought that the
leak was coming from the ptrap fittings.
This is a kitchen sink.
The strainer usually has no threaded adapter, it uses a plastic washer
different than a desanco washer.
I have not seen a kitchen sink strainer that you thread the tailpiece into.
