Can sewer gas enter my home from sewer lines?
Sewer gas can enter a building when the water located in a trap in the building evaporates. All fixtures that are connected to the sewer system must have traps on them. The water normally retained in the trap forms a barrier which keeps the gases from migrating from the sewer lines into the building.

If sewer gas is detected inside the building, flush water down each drain to ensure the traps are full of water. This will reinstate the barrier which keeps the gases from entering the building.
