Determining the gpm is tricky since the piping is sized based on fixture units. Los Angeles County grease interceptor detail. There needs to be a trap and vent between the fixture and the vented flow control fitting. If you are designing in the UPC, there is a table in the Code for sizing the interceptors based on pipe size and associated peak flow rate, and then assigns interceptor sizes based on one-minute and two-minute drain down times. In such cases, engineering drawings and supporting performance data must be submitted to and approved by the Director prior to GI installation. Interceptors ( clarifiers) (including grease, oil, sand, solid interceptors, etc.) 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.
