We live in a 2-story house with no basement and no crawlspace. Whenever the outside temperature drops to 20 or below, we get a sewer gas smell throughout the lower level of our house. We already checked the roof vent pipe and all is good with it. We already had the gas company check the inside & outside of the house and all is good. We already had a plumbing team out and they checked the inside & outside of the house and all is good. As soon as the weather warms up to 40 degrees, the sewer gas smell is gone. Unfortunately, we live in Chicago and the weather is going to be in the 20's for the next few weeks. Please advise & thanks.
