Septic smell under floor/in house
Posted by Anthony Gurley on November 09, 19100 at 07:40:58:
Can anyone help me? We sometimes have a problem with septic smells getting inside the house. This seems to be more of a problem in the fall/winter than in the warmer months. Vents are all good. Traps all have water in them. Smell seems to be originating from crawlspace then moving up into the house on certain days (?). We have poor crawlspace ventilation and I'm thinking maybe on colder days when temperature drops outside, the warmer air under the floor migrates up into the house taking the septic smell with it. Anyway, sounds like multiple problems but just wondering if anyone has had similar problem before so I might know where to concentrate first.
