A sewer smell that appears after rain usually means water is entering the sewer or septic system and pushing gas out. The entry point is the clue to the fix.

The septic
A septic field that saturates in rain can push odors up through the vents and the fixtures.
The dry trap
A trap that was nearly dry can lose its last seal as the pressure changes, and the gas escapes.
