What Grease-Trap Odor Can Indicate
Odor may increase when the interceptor holds excessive solids, the lid gasket leaks, a trap component is missing, wastewater stagnates, or a downstream restriction slows flow. Odor near several drains can also indicate a broader vent or sewer problem.
Odor Inspection
Seattle Plumbers checks:
- FOG and solids accumulation
- Lid, gasket, and access-cover fit
- Inlet, outlet, and baffle condition
- Flow through connected fixtures
- Drain and vent symptoms
- Cleaning history and waste loading
The odor location and timing help separate an interceptor issue from a dry fixture trap or sewer backup.
Cleaning and Correction
Service may include removing the interceptor contents, scraping interior surfaces, cleaning screens and baffles, reseating the lid, replacing a serviceable gasket, and clearing a restricted grease-waste line.
Cleaning can remove the material producing odor, but persistent smells may require vent, sewer, sanitation, or specialized contamination service.
Frequently Asked Questions
Will deodorizer solve the problem?
Fragrance can mask odor without removing FOG or correcting a failed seal. The source should be inspected.
Why does the smell return quickly?
Rapid return can indicate incomplete cleaning, heavy kitchen loading, a leaking lid, poor flow, or an interval that is too long.
