Manufacturer's are required to identify which Type their interceptor is rated to when certifying to the ASME standard. 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. Hunters Curve doesnt work because it is intended for water flow rates, not drainage. (See Article 2.5.5.2 for venting requirements for oil interceptors.) (a) in no case be less than 1 in.

When it comes to traps and vents for grease interceptors and the fixtures discharging to them, it's incumbent upon an engineer or contractor to identify and comply with local code requirements regardless what a manufacturer's drawing shows. Hydromechanical Grease Interceptors (HGI). Grease interceptors function using gravity and coalescence as a means of separation. 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. The following diagrams show some of the various approaches to common venting. level to allow for venting. If such is the case, they should be piped to the vent system and not left plugged, otherwise it may void the interceptor warranty. If it is a smaller indoor interceptor, some municipalities mandate servicing every 30 days. Most jurisdictions would say no because the interceptor is trapped internally.
