NSF can now test hydromechanical grease interceptors as large as 100 gallons per minute

ANN ARBOR, Mich. — NSF International, an independent global organization that writes standards, and tests and certifies products for the water, food and consumer goods industries, has expanded its testing capabilities for grease interceptors to include units as large as 100 gallons per minute (gpm).*

Used primarily in restaurants and commercial kitchens, grease interceptors (also called grease traps) prevent fats, oils and greases from entering the water system. This prevents clogged pipes, organic load charges from utility companies and surface and ground water contamination.

The higher-capacity 75-gpm and 100-gpm units operate at higher flow rates and collect more grease before needing to be emptied, which results in fewer workflow interruptions.

“NSF’s expanded ability to test the larger units provides manufacturers a full-service solution for testing and certifying their entire line of grease interceptors,” says Nasrin Kashefi, General Manager of Plumbing Programs at NSF International.

NSF certification is recognized by various regulators including plumbing inspectors, sanitarians and wastewater authorities. NSF testing and certification satisfies the requirements of all grease interceptor standards and codes including ASME A112.14.3, ASME A112.14.4, PDI G101, CSA B481, the Uniform Plumbing Code and the International Plumbing Code.

Laboratory testing verifies the performance, construction, grease retention and efficiency of grease interceptors at their designated flow rates. NSF Certified grease interceptors must have an average efficiency of 90 percent or higher, an incremental efficiency 80 percent or higher and the ability to retain 2 pounds of grease for each gpm of flow rate.

NSF’s Regulatory Affairs Hotline, 877-867-3435, is available to answer any questions about the acceptability of products in the field, including grease interceptors.

About NSF International: NSF International is an independent global organization that writes standards, and tests and certifies products for the food, water and consumer goods industries to minimize adverse health effects and protect the environment (nsf.org). Founded in 1944, NSF is committed to protecting human health and safety worldwide. NSF is a World Health Organization Collaborating Centre for Food and Water Safety and Indoor Environment.

NSF International's Water Programs require extensive product testing and unannounced audits of production facilities to verify that water treatment products meet the design, material and performance requirements. NSF International is accredited by the American National Standards Institute (ANSI).

NSF led the development of the American National Standards for all materials and products that treat or come in contact with drinking water. In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards. Today, all major plumbing codes require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.
