We just had a new house built.
It has a Septic with a pump up to a leech field. (Maybe 10ft rise). It is supposedly back vented (not sure what that means) but if the vent on the house was high enough we didn’t need a crazy high vent at the end of the leech field. And it was high enough. I think it vents backwards through the drain. Not sure any of that matters just letting you know.
Well the plumber wasn’t the best. Forgot plumbers putting on 2nd tub drain. And plumbed hot and cold backwards on the same tub. He was not keen on coming back as each cabinet came in and wanted to wait until everything was in and come once. Well I wasn’t gonna wait 6 months (and that was the spread on cabinets arriving). So I finished things myself As they arrived.
He mentioned which sinks need vents. Up stairs guest bath and kitchen sink. All seem fine.
I didn’t think this dual sink in master bath needed any under sink vents. But the sink on the left had a tiny bit of smell. Toilet is to the left of the left sink.
House is tricky because its post and beam and SIP (solid foam) for exterior walls. So he avoided most plumbing in any exterior walls.
I thought maybe the left sink plumbs over to the other sink on the right in the wall and might need a vent. I thought for sure at least one must be vented in the wall.
So I added the vent to the left sink and it’s much better but still get a whiff when I run the water. If I plug the drain, and run water, no smell. Sink on right never smells.
Could the possible need for a vent on the right sink cause the left one to stink? Could it be a bad vent?
This is the left sink. The right sink looks identical but no vent.
