It depends on which model plumbing code applies to the installation. The International Plumbing Code (IPC) 1002.1 (exception 3) allows a grease interceptor to serve as a fixture trap - where it is intended by the manufacturer to serve as a trap - for a single fixture or a combination sink of not more than three compartments so long as the vertical distance from the outlet of the fixture to the inlet of the interceptor is not more than 30 inches and the developed length of the waste pipe from the most upstream fixture outlet to the inlet of the interceptor does not exceed 60 inches. The drawing shows a PDI G101/ASME Type A grease interceptor with an external flow control with air intake, however it also shows a trap on the fixture but no vent for the trap. 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. The only solution for compliance with the UPC is to add a vent for the trap on the fixture upstream of the vented flow control fitting. Hydromechanical grease interceptors shall meet the following requirements: 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-corrodible materials; 1003.9 Venting of interceptors and separators. HGIs greater than 500 gallons must have a 60/40 split between compartments. in size in areas where it may be subject to frost closure. However, since PDI created this procedure, the health departments of the country have mandated indirect waste connections on prep sinks and the like, so drain down time cannot be controlled. HGIs are generally made from lined steel and are much smaller than gravity grease interceptors. In such cases, engineering drawings and supporting performance data must be submitted to and approved by the Director prior to GI installation.
