Frequently Asked Questions

Grease Trap FAQs

What is a grease trap and why is it required?
A grease trap (also called a grease interceptor or FOG interceptor) is a plumbing device installed between kitchen drains and the sewer system to capture fats, oils, and grease (FOG) before they enter municipal wastewater pipes. Health departments and municipal sewer authorities across the USA require grease traps for commercial kitchens to prevent blockages, sewer overflows, and environmental contamination. PDI G101-certified units are accepted by virtually all US jurisdictions.
What is the difference between a grease trap and a grease interceptor?
Both terms describe the same type of device — they trap and retain grease from wastewater. Historically, grease trap referred to smaller under-sink units (4–50 GPM), while grease interceptor referred to larger in-ground units for high-volume applications. Modern usage treats the terms interchangeably. Oil interceptors, sediment interceptors, and solids interceptors are related but separate products designed for non-food-service applications like auto shops and floor drains.
What size grease trap do I need for my restaurant?
Size your grease trap based on the total fixture unit flow rate of all drains that discharge grease-laden water — including sinks, dishwashers, and floor drains. A small café or food truck typically needs 7–10 GPM. A deli or quick-serve needs 10–20 GPM. A full-service restaurant needs 25–50 GPM. Large operations, hotels, and institutions need 75–500+ GPM. Use our size guide above or call 404-863-9232 for free expert sizing help.
What does PDI G101 certified mean?
PDI G101 is the standard of the Plumbing and Drainage Institute for grease interceptors. Units certified to PDI G101 have been independently tested to verify they effectively separate grease from wastewater at their rated flow rate. Most US cities, counties, and health departments require PDI G101 certification for commercial kitchen grease traps. All major brands we carry — Ashland, Canplas, Zurn, JR Smith, Rockford, and Mifab — offer PDI-certified models.
What is an oil interceptor vs. a grease interceptor?
An oil interceptor (like the Zurn Z1186 series) is designed for facilities that discharge petroleum-based oils, such as vehicle service bays, parking garages, car washes, and manufacturing facilities. A grease interceptor is designed for food service operations to capture cooking fats and oils. The internal design and certifications differ — oil interceptors typically include sediment buckets, oil drawoff connections, and vent ports. Never substitute one for the other without confirming compliance with local plumbing code.
What is an automatic grease recovery device (AGRD)?
An automatic grease recovery device (like the Goslyn GOS-40 or Rockford R-AGRU) continuously separates and collects grease using hydrostatic separation — no timers, no moving parts, no chemicals, and no scheduled pump-outs. The collected grease can be recycled. These units cost more upfront but eliminate ongoing pump-out fees, typically paying for themselves within a few years. NSF certified and ideal for high-volume kitchens.
How fast do grease traps ship from USA Equipment Direct?
Most in-stock units ship same day or next business day. Smaller poly and compact units typically arrive in 2–5 business days. Large interceptors (Rockford RGI series, Zurn Z1172) ship freight and may take 5–10 business days. Free freight is available on qualifying large interceptors to commercial addresses in the contiguous 48 states. Call 404-863-9232 for specific availability on any model.
