GRDs are similar to HGIs except they have a motorized wheel that skims the floating grease off the top of the waste stream and deposits it in a removable container that makes maintenance quite simple. That being the case the interceptor does not require a vented external flow control - jurisdictions unfamiliar with this type of interceptor often question drawings like this and understandably so. (a) connect to the interceptor at opposite ends, (c) terminate not less than 2 000 mm above ground and at elevations differing by at least 300 mm, and. hb```@9 Failure to service a grease interceptor on a routine and timely basis can result in complete back-up of the kitchens plumbing system. Accept all cookies 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). Where large central grease interceptors are entirely impractical, such as my old stomping ground of New York City, localized interceptors become the most practical solution. This is fine if the waste hauler has a means of access to the unit with their vacuum hose, but often they are mistakenly buried in the parking garage where no such access exists, and a grease truck is much too tall to drive into a parking garage with 8'-4'' ADA clearance. The code does allow the interceptor to serve as a trap (assuming that this interceptor is intended to serve as a fixture trap) thus adding a trap to the fixture upstream of the interceptor creates a double trapped fixture installation.

The UPC does not include provisions for AAVs except as a part of an "Engineered Vent System" under section 912.0, much to the chagrin of engineers around the country. | Change settings. I would size it as half the size of the inlet with a 2-inchminimum, but your AHJ might want you to use the connected fixture units so it is worth checking with your AHJ. This drawing shows a semi-automatic draw-off type grease interceptor but without a vented external flow control. . Since the interceptor comes with a flow control in the inlet, if your drainage flow rate exceeds the rating of the interceptor the waste will back up and end up on the floor. 1003.3.4 Hydromechanical grease interceptors, fats, oils and greases disposal systems and automatic grease removal devices.
