Sewer smell in a house means gas from the drain system is getting past a water seal or through a crack. The cause can be a dry trap, a failed wax ring, a cracked vent stack or a hole in a cast iron drain under the slab.
A smoke test fills the drain system with harmless smoke and shows where it escapes, from a wall, a baseboard or the floor. A camera then inspects the drain at that spot. Sewer gas contains hydrogen sulfide and methane, so a persistent smell should be found and fixed.
In Bradenton homes with original cast iron, odor often comes from a cracked fitting under the slab or a rusted vent in a wall. Humid summer weather makes the smell stronger.
