Why Does My House Smell Like Sewer?
An unexplained sewer odor may come from a dry drain trap, a toilet seal, a dirty drain, or a larger problem within the sewer system.
The location and timing of the odor can help narrow down the cause, but persistent smells should not be ignored.
An Unused Drain May Have a Dry Trap
The curved section of pipe beneath a sink, tub, shower, or floor drain is designed to hold water. This water creates a barrier that helps prevent sewer gas from entering the building.
When a fixture is not used for an extended period, the water can evaporate. This is particularly common in guest bathrooms, basements, utility rooms, and other infrequently used areas.
Running water into an unused drain may refill the trap. If the smell returns, another issue may be responsible.
The Odor May Be Coming From a Toilet
A damaged or poorly sealed connection between a toilet and the drainpipe can allow odors to escape. A rocking toilet, moisture near the base, or a smell concentrated around the fixture may indicate that the toilet needs to be inspected.
Avoid repeatedly tightening a loose toilet without identifying why it is moving. The fixture, flange, floor, or seal may require repair.
A Drain or Sewer Problem May Be Developing
Buildup inside a drain can collect organic material and produce unpleasant smells. Sewer odors accompanied by slow drainage, gurgling, wet areas, or backups may point to a clog, leak, or damaged sewer line.
American Rooter notes that sewage smells can indicate a clog, leak, or more serious sewer issue. A camera inspection may be used when the source cannot be identified from accessible fixtures.
