Grease Interceptors may be sized in accordance with Appendix H of the 2003 Uniform Plumbing Code (UPC) or Chapter 10 of the 2006 and 2009 . 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). Like HGIs, they can be recessed in the floor, located on the floor below, or sit on the floor next to a single fixture. For compliance with the UPC this drawing would have to show both a vented external flow control and a trap and vent for the fixture. Both HGIs and GRDs are sized based on the flow rate of the waste stream in gpm. Must comply with American Society of Civil Engineers (ASME) A112.14.3 standard; Must be flow-rated at 75-gallons per minute (GPM) or higher; Must be constructed of non-corrodiblematerials; Must be installed per ASME A112.14.3 Type D standard (indirect connection without external flow control); Must have a minimum liquid capacity consistent with the IW approval letter specified minimum; and. It depends on which model plumbing code applies to the installation. Drain down cant be controlled to two minutes due to the presence of air gaps on many of the fixtures.
