Section 890.510 - Grease Interceptor Requirements, Ill - Casetext Or do you size it based on the number of fixture units connected upstream? ASME A112.14.3 allows four types of ratings as follows: Type A - units with external flow control, with air intake (vent): directly connected, Type B - units with external flow control, without air intake (vent): directly connected, Type C - units without an external flow control: directly connected, Type D - units without an external flow control: indirectly connected. Use our online tool to determine what size grease interceptor you need, Grease Interceptor Installation Plan - Request a Metro Vancouver Review. Here are a few examples. You would think after being around so long that the plumbing associated with these units would be long established and well defined, but it is not. Metro Vancouver respects the diverse and distinct histories, languages, and cultures of First Nations, Mtis, and Inuit, which collectively enrich our lives and the region. grease interceptor. 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; F. Concrete or finishing material requirements are to be determined by the specifying engineer. The letter will specify a minimum frequency. 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. %PDF-1.5 % dwellings. Either adding a vent to the trap or removing the trap on the fixture altogether would solve the problem. PDI G101 and ASME A112.14.3 Type A certified interceptors are required to have a vented external flow control installed upstream of the interceptor. If you do provide a vent, how do you size it? As the waste stream flows through the orifice in the flow control device negative pressure is created, drawing in air from the air intake which is intended to mix with the waste water as it enters the grease interceptor aiding in separation efficiency. TRAP REQUIREMENTS. Does the unit need a running trap as shown in the 25-year-old detail by the county of Los Angeles? (d) do not connect to each other or any other vent pipe. e.) Venting is recommended on both the inlet and outlet side of the interceptor, or as governed by local code. Traps, interceptors and separators - LII / Legal Information Institute A grease interceptor is not required where only one auto . I, and many others, have written about grease interceptors, probably because their design requirements are quite vague and interpretation varies all over the map.

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. . Examples of such features would include a flow diverter plate in the primary compartment, "tee" piping between the two GI compartments and "tee" piping on the tank outlet; Be constructed of concrete or non-corrodible materials; Each GI compartment shall be accessible for cleaning and inspection purposes (no exceptions). Conceptual drawing of a City of Austin approvedgravity grease interceptordesign. Building on our expertise and field-proven approach to grease and solids management, Endura XL consistently offers high performance hydromechanical grease management, with some of the industry's highest fats, oil and grease separation efficiencies. Again, there is nothing wrong with this installation, though it may not be immediately obvious as to why. %PDF-1.5 % The vent on the flow control is an air intake. You can ask Metro Vancouver to review your installation plan. L/m, 1 pound = 0.454 kg. 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. A grease interceptor shall be provided for proper handling of liquid wastes containing grease. 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.

Product Details - Endura Grease Interceptors Trapping and Venting for Grease Interceptors - Interceptor Whisperer The approved design for GGIs shall be as follows: Exceptions to the above criteria may be considered for approval in conjunction with the Building Plan Review process. 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. 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. Section 890.510 - Grease Interceptor Requirements. not required in garage floor drains in one-, two-, and three-family What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. Los Angeles County grease interceptor detail Some of these large interceptors (basically the plastic ones) come with vent connections on the tank itself. I dont know about you, but, for me, 2016 was a very difficult year, and I am not sorry to see it go.
