I have a strange odor coming through my heat vents.
I had a sewer cleaner come out and clean my sewer
Lines. The odor is still there.
I don't have a septic tank.

Hi wdoxie:

Hey, sewer gas can be an awful smell... and it can linger for a long time. If this were me I would bleach down the area (20% bleach solution or so) he worked in and see what happens from there... should disappear soon.

OR the plumber left you a present somewhere... :p Did you pay your bill in full? Hey, like I said, bleach the area.. that should help.

Good luck... Mark
