p trap to tailpiec connection

Both bathrooms on the second floor of my home are plumbed so that condensation from the inside A/C units drains into a connection welded into the top of the tailpiece. I was having leakage at the p trap/tailpiece connection in one of the bathrooms - checked out the other and it appears the p trap is connected to the metal tailpiece with a simple connector - however, when I replace the p trap in the leaking unit with new parts, it continues to leak. Looks like the water is just coming up between the washer and the pipe. Am doing something stupidly, fundamentally wrong, or is there an easy solution?

Welcome to the forums! Not sure if the code applying to your installation allowed that configuration or not, but you can't do that any more. But it may not be causing your problem in itself. Some simple questions so forgive me. Are you using a nylon wedge type washer between the tailpiece and ptrap end? Is your ptrap metal or plastic?

Thanks for your response. P Trap is 1 1/2" plastic, tailpiece is 1 1/4" metal - and the washer is the nylon wedge type. I've examined the other bath with a similar configuration and it has never leaked...I don't think the draining of the a/c into the tailpiece is really the underlying problem - it leaks if I run the faucet long enough to fill the trap and back up a bit...thanks again.

Are you using the thicker washer designed for 1 1/4" pipe?

Yep...I have it with the smaller end on top, against the connector...

Thanks again.

Reverse it. The larger end goes against the connecting nut.
