sewer gas smell in attic, garage and around home
Posted by James Thomas on January 04, 2002 at 17:23:03:
We have a one year old ranch walkout home with septic system. There is a distinct sewer gas smell around the outside of the house, and, depending on which way the wind blows, in the garage as well. Odor is very bad in the attic space. Plumber has installed some type of valves in roof venting pipes to no avail. All toilets, etc. work fine but the smell is driving us crazy. Builder cannot find any cracks or holes in pipes in attic. What might be going on here?
