If you fill it up to the overflow, does it drain into the overflow or just fill that cavity?
Smell from sink drain
Our bathroom was remodeled probably around 9 months ago or so. All plumbing used was HVAC. We moved the sink and the toilet drain and connected them back into the larger house drain. I notice that over time a smell comes from the sink drain. More noticeable if you're bent down washing your face or something. I've had some success with using lye as a drain cleaner. I'm guessing something is not quite plumbed right and I'm basically smelling buildup in the catch or something. Is there a drain cleaner that I should use? Liquid or perhaps motorized or something? Thanks!

Possibly the sink's trap is being siphoned out allowing the sewer gas to enter the house.
My guess is, when you re-plumbed the sink and toilet on the same line you created a siphon effect on the sink's trap.
Hope you get it figured out and corrected soon bluegrass.

So it turns out the overflow is not hooked up. While the sink has never been filled (until now) to reach the overflow, obviously water can get back there in general. That said, there doesn't appear to be any smell coming from the overflow holes, rather only where the stopper in the drain is.
After flushing the toilet run a little water in the sink. If that makes it go away, you have problem with the vent and you can put a cheater in.So it turns out the overflow is not hooked up.
