Grease Interceptor Installation Bay Area

The terms are often used interchangeably, but they describe different equipment. A grease trap is a smaller, typically indoor unit installed under or near a sink, suited to lower-volume kitchens. A grease interceptor is a larger unit, often installed outside or below-grade, sized for higher-volume commercial kitchens. Which one a property needs depends on wastewater volume and local sewer authority requirements.

Undersized interceptors are one of the most common causes of grease-related sewer violations — the unit simply can’t hold enough capacity between pump-outs for the kitchen’s actual grease load. Sizing depends on fixture count, meal volume, and the requirements of the local sewer or wastewater authority, which we calculate before recommending equipment rather than defaulting to a standard size.

Installation involves tying the interceptor into the kitchen’s wastewater line ahead of the sewer connection, sized and positioned per local health department and plumbing code requirements, with permits pulled and inspection scheduled as part of the job. Once installed, interceptors need regular pump-outs and inspection to stay compliant — we can also service and pump existing interceptors that are due for maintenance.
