Sewer Smell in the House: Common Causes
Dry P-traps
Unused showers, guest sinks, and floor drains can lose the water seal that blocks gas. Running water for a minute often solves it.
Toilet wax ring
A failed seal under a toilet lets gas escape at the base. Rocking or staining around the toilet is a clue.
Vent problems
Blocked or damaged roof vents can pull trap water out and let odor in.
Cracked drain or sewer pipe
If simple fixes fail, a cracked line under the slab or in the yard can release gas. A camera inspection is the way to confirm it.
