Sewer odor prevention checklist

For Chicago-area homeowners — check off tasks as you complete them

Progress 0 of 12 complete

Monthly

Run water in all unused drains to keep P-traps full

Floor drains, guest baths, basement sinks

Check under sinks and around toilet bases for new odors or moisture

Early sign of a failing wax ring or slow leak

Clear drain screens of hair, food, and debris

Kitchen, bathroom, and laundry drains

Seasonally (every 3 months)

Flush kitchen drains with boiling water to break down grease buildup

Prevents slow accumulation that causes odors and clogs

Inspect your yard for wet spots or unusually lush grass patches

Can indicate an underground sewer line crack

Check roof vent pipes for debris, ice, or animal nests

Blocked vents push sewer gas back into the home

Annually

Schedule professional drain cleaning for main lines

Removes buildup before it causes backups or odors

Have catch basin pumped out if your property has one

Organic buildup in catch basins is a major odor source

Test sump pump operation before spring rain season

Especially important in Chicago freeze-thaw months

Every 2–3 years

Schedule a sewer camera inspection of your main line

Critical for homes built before 1980 with clay or cast iron pipe

Have a professional hydro jet your sewer lines

Removes grease, roots, and mineral buildup that rodding alone misses

Assess wax ring seals on all toilets, especially older bathrooms

Failed seals release sewer gas with every flush
