Sewer vents Under soffit
We built a new home in Cle Elum Washington. Our sewer vents go out under the soffits and not thru the roof. We consistently have sewer smells outside around the house (not in the house). We are on septic and only lived in the house for 2 months. I have also noticed the sewer order around other new homes in the neighborhood. The builder flushed bakers yeast down our toilets that said should activate the system. He also said there was some kind of coal screen vent he could install in the vents to eliminate order from escaping. I also understand we can run these vents thru the roof which our builder is willing to do. Any ideas to solve our sewer smell?
