Hello,
I've just replaced my old corroded and leaking cast-iron pipes under my kitchen sink in my 100 year-old home with new PVC tubing. For the most part, things have worked out well.
However, I have a consistent leak where my tubing enters the horizontal drain pipe in the wall. I've tightened the slip nut; i've applied a little bit of teflon paste to the washer; i've ensured the the pipes are properly aligned (my pvc tube feeds ~4" into the drain pipe; but I cannot stop this leak. It only occurs when I run a leak test and dump a sink-full of water through at once, not during regular running.
What can I do to stop this leak? I suspect the issue is the low-quality poly washers that are included in the pvc tubing kits; but they seem to be working elsewhere in the system I'm not totally sure on that. I've got very little plumbing (read: none) experience so any input is helpful!
Thanks!
