Hi all,
I just installed a new counter with builtin sink made of mezanite and after I installed the faucett and sink drain, there is a slow drip when using the sink.
The sink is odd in that it has no vent for the drain, it is a simple bowl with a hole in it. The drain pipe is made of some plastic material with a rubber gasket that goes under the sink and tightened by a large nut on the pipe. The pipe does have holes near the top which I assume are there to accomodate a vent/overflow, which my sink does not have.
Instructions that came with the pipe said to use teflon tape on the top of the pipe which threads onto the shiny flange peice on the inside of the bowl. I have done this twice. Second time, I used the thicker teflon tape and it still drips. I am afraid of overtightening the nut to stop the drip. Is it possible that the drip is coming from the lower part of the pipe, where the big rubber gasket is? Should I teflon tape there too?
I was also thinking of doubling up with pipe dope and tape.
Any suggestions, other than 'call a plumber', will be appreciated. This is not rocket science, I just need a pointer or two.
Thanks,
Larry
