Rockford RP-35-LO-SS All Stainless Low-Profile Grease Interceptor – 70 lb, 35 GPM, 4" No-Hub
Rockford RP-35-LO-SS — All Stainless Steel Low-Profile Grease Interceptor, 70 lb / 35 GPM
The Rockford RP-35-LO-SS delivers the full performance of Rockford's RP-35 interceptor — 70 lb grease capacity and 35 GPM intermittent flow — in an all stainless steel, low-profile body standing only 13.25" tall. When under-slab depth, shallow utility chase dimensions, or tight mechanical clearances rule out a standard 22" unit, the RP-35-LO-SS provides the same heavy-duty interceptor performance without the vertical footprint. Features a 20-gallon static holding volume and 4" no-hub inlet/outlet connections. Backed by a lifetime warranty, certified to PDI-G101, and manufactured in Rockford, IL.

Frequently Asked Questions
What does "LO" mean in the RP-35-LO-SS model number?
“LO” stands for Low Profile. The RP-35-LO-SS is only 13.25" tall — versus 22" for the standard RP-35-SS — making it the correct choice when under-slab clearance, shallow floor recess, or mechanical room height restrictions prevent use of a full-height interceptor. Both units share identical 35 GPM / 70 lb performance.
What is the grease capacity of the RP-35-LO-SS?
The RP-35-LO-SS holds 70 lb of grease and sludge with a 20-gallon static liquid holding capacity — the same performance as the standard RP-35-SS, delivered in a low-profile body engineered for tight vertical clearances.
Does the RP-35-LO-SS come with a warranty?
Yes — the RP-35-LO-SS carries a lifetime manufacturer's warranty as part of the Rockford RP-SS stainless series. All stainless construction eliminates the corrosion and paint failure risks that limit the service life of standard carbon steel units.
Can the RP-35-LO-SS be installed flush with the floor?
Yes. The RP-35-LO-SS supports both on-the-floor and flush-with-the-floor installation. Its low profile makes it especially well-suited for flush installations in shallow recesses. The 3/16" stainless diamond tread cover is pedestrian-rated for walk-over safety.
Is the RP-35-LO-SS PDI-G101 certified?
Yes. The RP-35-LO-SS is certified to the Plumbing & Drainage Institute PDI-G101 standard, meeting the grease interceptor performance benchmarks required by plumbing authorities and health departments nationwide.
What is the difference between the RP-35-LO-SS and the RP-35-SS?
Both units are all stainless steel with 35 GPM / 70 lb performance. The critical difference is height: the RP-35-SS stands 22" tall; the RP-35-LO-SS is only 13.25" tall — engineered specifically for installations with limited vertical clearance below the drain line.
