Rockford RP-250 Grease Interceptor – 500 lb, 250 GPM, 509-Gallon, 4" No-Hub

The RP-250 holds 500 lb of grease and sludge with a 509-gallon static liquid holding capacity — the largest standard capacity in the Rockford RP interceptor series. It is designed for the highest-volume commercial kitchens, institutional facilities, and industrial food processing operations.

The RP-250 is rated for 250 GPM intermittent flow with a 4" no-hub inlet and outlet and an integral flow control device — handling the peak combined drain output of large multi-station kitchen operations.

The RP-250 ships by freight carrier at 969 lb (approximately 1,050 lb with pallet). Free freight is included for deliveries to the lower 48 states. A lift gate is required to lower the unit from the truck — please add lift gate service at checkout if your facility does not have a loading dock or forklift. Confirm delivery site access for the 61" × 42" × 63" unit footprint.

Yes. The RP-250 supports both on-the-floor and flush-with-the-floor installation. The 3/16" nonskid diamond tread plate cover is pedestrian-rated for walk-over traffic and secured with stainless flat-head screws for service access. Note the unit's 63" height — plan installation depth accordingly for flush installs.

Yes. The RP-250 is certified to the Plumbing & Drainage Institute PDI-G101 standard — the nationally recognized benchmark for grease interceptor performance required by most municipal plumbing codes and health department regulations.

The RP-250 represents the top of Rockford's standard RP interceptor series — with 500 lb grease capacity and 509-gallon holding volume, far exceeding models like the RP-150 (300 lb / 188 gal) or RP-100 (200 lb / 125 gal). It is engineered for facilities where continuous high-volume kitchen drain flow would quickly overwhelm a mid-range interceptor.
