Frequently Asked Questions
What is the difference between the RP-50 and the RP-50-SS?
Both units share identical 50 GPM / 100 lb performance and dimensions. The key difference is material: the RP-50 is all-welded carbon steel with enamel coating inside and out; the RP-50-SS is all stainless steel — body, cover, and fasteners — with no enamel coating. The SS version carries a lifetime warranty versus the standard warranty on the carbon steel model.
What is the grease capacity of the RP-50-SS?
The RP-50-SS holds 100 lb of grease and sludge with a 35-gallon static liquid holding capacity — suitable for large commercial kitchens, cafeterias, and institutional food service operations generating high grease loads.
Does the RP-50-SS require a vent?
The RP-50-SS comes standard with an internal trap seal and air bypass, which handles venting within the unit. Always consult your local plumbing code for site-specific venting requirements before installation.
Can the RP-50-SS be installed flush with the floor?
Yes. The RP-50-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 safe walk-over access.
Is the RP-50-SS PDI-G101 certified?
Yes. The RP-50-SS is certified to the Plumbing & Drainage Institute PDI-G101 standard — the nationally recognized benchmark for grease interceptor performance and the certification required by most municipal plumbing codes and health departments.
What warranty comes with the RP-50-SS?
The RP-50-SS is backed by a lifetime manufacturer's warranty. All stainless steel construction — with no enamel coating to crack or corrode — makes this warranty practical: the unit is designed to outlast the building it's installed in.
