Sewer odor from vent stacks?????
Posted by Shannon on February 07, 19101 at 18:54:39:
Hi, we've been noticing a sewer gas smell drifting around outside and found it is coming from the vent stacks on the roof. Have checked all traps and such, is a new home, all looks fine. Is there supposed to be a sewer smell coming from these vents? Also, we found we have the newer "internal" vents underneath each sink, would this have anything to do with it?
Any help/feedback is appreciated.
