Good Day Folks,
I have a problem with a vent pipe on a bathroom creating a nasty smell on our deck when it's cold out. It seems inversion is bringing the smell down to deck height and when we're in the hot tub on cold evenings it's obnoxious. The vent is approximately 14 feet from the hot tub.
Is there anything you all can think of besides rerouting the vent to a higher location? Doing so would necessitate cutting into the ceiling as the attack space above this bath is only 3' at the peak. I've looked at air admittance valves but I don't think this will work on the exterior.
Thanks so much!
