Frequently Asked Questions
What is the difference between the RP-35 and the RP-35-SS?
The RP-35 is all-welded carbon steel with interior and exterior enamel coating. The RP-35-SS constructs the entire unit — body, cover, and fasteners — from stainless steel, providing superior corrosion resistance, easier sanitation, and a lifetime warranty. Both share the same 35 GPM flow and 70 lb grease capacity.
What is the grease capacity of the RP-35-SS?
The RP-35-SS holds 70 lb of grease and sludge with a 30-gallon static liquid holding capacity. It is designed for large commercial foodservice operations — large restaurants, institutional cafeterias, and multi-station food service lines with heavy FOG discharge.
Does the RP-35-SS come with a warranty?
Yes — the RP-35-SS is covered by a lifetime manufacturer's warranty as part of the Rockford RP-SS stainless series. All stainless construction eliminates the corrosion and enamel failure risks that can affect standard carbon steel units over time.
Can the RP-35-SS be installed flush with the floor?
Yes. The RP-35-SS supports both on-the-floor and flush-with-the-floor installation. The 3/16" stainless diamond tread cover is pedestrian-rated and fastened with stainless steel flat-head screws for safe walk-over access and easy cleanout service.
Is the RP-35-SS PDI-G101 certified?
Yes. The RP-35-SS is certified to the Plumbing & Drainage Institute PDI-G101 standard — ensuring the unit meets the grease interceptor performance requirements recognized by plumbing authorities and health departments nationwide.
What connection size does the RP-35-SS use?
The RP-35-SS uses 4" no-hub inlet and outlet connections with an integrated flow control device — the standard pipe size for the RP-35 and larger interceptor models. No-hub couplings enable fast, leak-free installation without threading or soldering.
