I picked up a small tube of the PTFE Plumbers Paste and filled the open-wedged piece with it. I also applied a little to the threads, as recommended above, and it went much smoother. The paste on the threads made the nut tighten up much much easier than it previously did and the liberal amount of paste I put in the wedge filled the void where it was leaking. I ran hot water through the drain for about 10 minutes and not a single leak!

Thank you so much for the replies! I've been a member here for several years but it was actually a google search that brought me to this thread. Hopefully future searchers will benefit from the newly added replies.

I'm curious as to why you didn't replace the old P-trap with an original type pvc one.
You could try to wrap some teflon tape around the threads for a better seal
I'm sure a plumber will chime in soon
He said "Plumber Butt"..

Re: leaking p-trap after replacing

For diggitydog: Thanks for the help. Looked a while on the internet before I found your solution. It's aces! FYI Task was to reattach the trap after cleaning. My wedge had a small spur (thin piece of plastic) that the plumber failed to remove when it was installed originally. I recall he had a problem getting a seal. I removed that with my fingernail, cleaned off the other sealant I had tried, used your recommendation (I found Real-Tuff PTFE Paste Thread Sealant at Home Depot) and voila! It was sealed. (For those getting here wanting to know if sealant is absolutely necessary, all I can say is that the plumber used it and I used it - and it seals) Thanks again
