P-trap leaking

I removed a pvc p-trap at a bathroom sink to clean it out, and after reassembling, it has a slow leak at the top of the (outlet end) slip-joint nut. Reassembled it many times but it just slowly leaks out at other parts around the slip-joint nut each time. Wasn't leaking before being taken out for a clean.

Change the nut and nylon compression ring---clean the mating surfaces well--that should do it--

Often the nylon compression ring gets stretched and starts to seep a bit.

OOPS! You didn't tell weather the pipe was plastic or chrome---

If metal use a rubber compression ring.--Mike--

Thumbs up

Thanks Mike for the quick reply.

I believe, after so many time-consuming leak tests, that it is no longer leaking. The pipe is pvc. My setup had the ring integrated into the pipe it was connected to.

For anyone else experiencing similar problems, it might help to reconnect the sink/tail end last instead of repeatedly trying (as I did without success) to adjust the nut at just the outlet end.
