Re: Intermittent Sewer Smell Inside the House
Finding something that's intermittant is always a chore.
The first thing in my mind is to verify that is indeed sewer smell or a musty mold smell .
Considering that it appeared after a rain and that the gound under the floor is only about 8 inches strongly suggests a damp issue in the crawl space and might be migrating up into the living space through some sort of pentration in the flooring.
One common source of intermittant sewer smell is from a poor wax seal joint at a toilet.
2 cents worth.
