I discovered a leak under my bathroom sink. There are two sinks in the bathroom with the same plumbing set up and only the one side is leaking. The water is coming from the marvel connector on the pipe coming out of the wall. The connector is 1-1/2 in.
There are just bare threads on this connector – no nut or anything… Is that even a viable setup or did someone cut corners when installing this? The red arrow shows where the water is leaking from.
Does this seem like an easy fix? I've noticed a bad smell coming from the pipes once in a while and that's leading me to question the entire setup. I'm wondering whether I can just slip a nut on there or if I'll need to replace the whole P trap.
Any tips or guidance would be much appreciated.
Thanks!

What is missing on this setup is the compression nut. It should fit over your 1 1/2 inch drain pipe going into the wall stub. When you tighten it down the inner gasket will seal around the drain and prevent water and odor from escaping into the room.
This looks like a poor diy job. The problem may have been that the bend in the drain pipe before the Marvel connector prevents the nut from properly threading on the connector. Regardless, you need that compression nut on there. You can pick one up from any home supply or plumbing store. You may have to buy the entire connector. You're also going to have to play with the P trap to get it properly aligned so the nut will thread on. There is play in the pipes. As a last resort you may have to buy a longer 90 degree drain section coming out of the P trap and rotate the P trap 90 degrees toward the front of the sink to get a straight shot into the stub.
