New P-Trap Leaking

[newhomeDIYer]

Hi all - P-Trap for my vanity was stinking and had a small leak. So I've just replaced my P-Trap with the exact brand from before. This piece here is leaking so bad and I just don't know what I can do. The product is by Mueller and it did not come with a washer. I've tried with and without plumbers tape on the threads but it doesn't help. I'm scared if I keep tightening, it may overtighten and crack.


Are there any suggestions from the pros on what I can do? Thanks in advance!

Those two pieces join at an internal conical sealing surface molded into the two mating pieces. Tape on those threads will not seal that union. With both ends of the trap glued in place, and such a short trap arm, you may have glued them slightly crooked, not allowing the sealing surfaces to mate. You can try to tighten the nut, and if that doesn't work or it breaks, you will probably have to redo the P-trap. Remove any and all tape from the joint first.

Good luck.

Probably needs tightened more, make sure the mating surfaces are seated together and not out of alignment.

Take it apart, dry it and apply some silicone to the mating surfaces, not the threads.
I had to do that last week.

I've found I always wrench those nuts too tight with my hands. Now, I slightly snug them. Mc and GR are probably correct, and the surfaces are just a tad bit out of alignment.

I use Teflon paste or any pipe dope on the union faces and a dab on the threads

probably misaligned or faulty piece.
