Hydromechanical grease interceptors shall meet the following requirements: Generally, HGIs are ideal for low FOG-producing establishments such as small sandwich shops, coffee shops, and bakeries that use disposable flatware and do not utilize an automatic dishwasher, due to the HGIs compact size. %%EOF I would argue the former since, as noted above, each connected fixture is already trapped and the vent just serves to allow for the displacement of air it is not protecting a 1'' trap seal. Grease Interceptor are manufactured with patented distributed flow pattern and corrosion resistant fiberglass material capturing FOG before it clogs pipes, enters the sewer waste system, or spoils a successful operation. Metro Vancouver's Food Sector Grease Interceptor Bylaw 268 requires commercial and institutional kitchens to install and maintain a grease interceptor to reduce fats, oils and grease (FOG) in the sewer system. %%EOF . Exception: The retention capacity of grease interceptors (in pounds) must be at least twice the numerical value of flowrate through the unit (in gallons per minute). Therefore, when using an AAV to vent a grease interceptor, it's important that the drainage system has provision for the relief of positive pressure to ensure proper flow.
