Frequently Asked Questions
What is the greasy sludge capacity of the RGI-1250?
The RGI-1250 holds 6,300 lb of greasy sludge across its 1,250-gallon two-compartment liquid volume — designed for extended service intervals in very high-volume commercial food service operations.
How does the two-compartment design benefit FOG separation?
The first compartment captures the bulk of grease and solids as the high-velocity kitchen discharge slows down. The second compartment provides additional gravity separation before the clarified effluent exits to the sewer — more effective than a single-chamber unit of equal volume.
Can the RGI-1250 handle heavy truck traffic?
Yes. The 3/8" nonskid diamond treadplate cover is H20 load rated — rated for commercial and highway truck traffic. The unit can be installed flush with grade in parking lots, loading areas, and service drives where vehicles cross the cover.
Is the RGI-1250 returnable?
No. The RGI-1250 is custom-built to order and non-returnable. Confirm capacity, manway height, pipe sizes, and local plumbing code requirements with your engineer or plumbing inspector before ordering.
Can the manway height be customized?
Yes. The standard RGI-1250 ships with 6" tall manways. If the unit will be buried deeper or installed under a paved overlay, specify the required manway height at time of order.
What construction standard does the RGI-1250 meet?
The RGI-1250 is built to IAPMO/ANSI Z1001-2014 — the nationally recognized construction standard for fabricated gravity grease interceptors, referenced by commercial plumbing codes across the United States.
