When Cleaning Is Due
Cleaning is due before accumulation interferes with separation or flow. Warning signs include odors, slow sinks, high water, visible grease at the outlet, and FOG plus solids approaching 25 percent of capacity.
Our Cleaning Process
Service varies by trap size and access, but may include:
- Opening the lid without damaging gaskets
- Measuring grease and solids layers
- Removing water and accumulated waste
- Scraping walls, lid, baffles, and accessible tees
- Cleaning screens and removable components
- Reassembling parts and restoring water
- Testing connected fixtures
- Recording findings and service date
Large gravity interceptors may require pump-truck service rather than manual cleaning.
Maintenance Findings
Cleaning exposes cracked baffles, corroded fittings, damaged lids, failed gaskets, and unusual solids loading. We report these findings and recommend repair or replacement when needed.
Frequently Asked Questions
How often should a grease trap be cleaned?
Follow manufacturer specifications and measured accumulation. Seattle requires cleaning before FOG and food waste exceed 25 percent of the interceptor.
Can additives replace cleaning?
No. Seattle prohibits emulsifying agents, enzymes, bio-additives, and similar chemicals in grease interceptors.
