I wrote earlier regarding the sewer odor in my home. New information- I only experience the smell in the evening when I’m using my fireplace. Is the draw of the fire burning somehow bringing the sewer smell into the house?
jvanhalle, It very well could be, and you may have a leak in your vent system. Modern houses are so air tight these days that the combustion air for your fire could be coming from a leak in the vent system. JWA
