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.
Any advice?
Much obliged in advance, snipped-for-privacy@yahoo.com
