Moved into this house 6 months ago right after the previous owner put in a new septic tank. Previous tank was filled with sand. Almost immediately we noticed a sewer smell on the back deck. Over the last 3 months the smell has moved indoors (still outside as well) and is more an eye burning mix of fumes mixed with some sewer smell and a smell of rotten or burning food (??!!). Always seems to be worst in the TV room but is really all over the house. It seems to move around. Always gets worse in the early evening or night. When I take off the septic tank riser to inspect the smells get better for a day or 2 but always return.
We have tried carbon filters on roof vents, 5 plumbers, 3 septic companies, and 2 HVAC firms. Everyone seems to be stumped! The last plumber scoped the sewer lines to the tank and the main stack vents near the TV room and couldn't find anything. The carbon filters worked great for the outside smell but the inside smells got worse.
We are about to lose our minds! (along with our lung capacity!). Any thoughts?
