Frequently Asked Questions
What is the difference between the RP-20 and the RP-20-SS?
The RP-20 is all-welded carbon steel with interior and exterior enamel coating. The RP-20-SS builds the entire unit — body, cover, and fasteners — from stainless steel, providing superior corrosion resistance, easier sanitation, and a lifetime warranty. Both models share identical 20 GPM flow and 40 lb grease capacity.
What is the grease capacity of the RP-20-SS?
The RP-20-SS holds 40 lb of grease and sludge with a 13-gallon static liquid holding capacity. It is sized for full-service restaurants, hotel kitchens, and catering operations with moderate-to-heavy FOG discharge rates.
Does the RP-20-SS come with a warranty?
Yes — the RP-20-SS is backed by a lifetime manufacturer's warranty as part of the Rockford RP-SS stainless series. All stainless construction eliminates the corrosion and paint failure that limit the service life of standard carbon steel units.
Can the RP-20-SS be installed flush with the floor?
Yes. The RP-20-SS supports both on-the-floor and flush-with-the-floor installation. The 3/16" stainless diamond tread cover is pedestrian-rated and secured with stainless flat-head screws for easy walk-over and cleanout access.
Is the RP-20-SS PDI-G101 certified?
Yes. The RP-20-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 connection size does the RP-20-SS use?
The RP-20-SS uses 3" no-hub inlet and outlet connections with an integrated flow control device. The step up from 2" to 3" connections begins at the RP-20 series and accommodates the higher flow rates of larger commercial kitchens.
