Dear Experts,
Can anyone suggest how best to fix a drip from my kitchen sink waste?
It's a modern stainless-steel sink. The strainer-type waste is fixed into a large diameter hole in the steel; that is OK. Next is a vertical plastic pipe with two inlets for appliances, leading into the U bend. It seems to be the joint between the waste and this vertical pipe that is leaking.
The joint has a fairly thick and firm rubbery flat washer. This fits between flanges on the top of the pipe and the bottom of the waste and is held by a plastic nut, captive on the end of the pipe.
I have dismantled and cleaned it, replaced the washer, and reassembled tightly - but it still leaks.
One thing I've noticed is that the flange on the top of the pipe against which the washer rests is imperfect. I could try to flatten it with some sandpaper, but that could make it worse rather than better, and might not be the cause of the problem.
Would I be better filling it with sealant or grease of some sort, or getting a differ sort of washer? Any "tricks of the trade" to resolve this sort of leak?
Thanks, Phil.
