Keep a record of grease interceptor cleanouts and maintenance activities. Use our online tool to determine what size grease interceptor you need, Grease Interceptor Installation Plan - Request a Metro Vancouver Review. There needs to be a trap and vent between the fixture and the vented flow control fitting. Sizing of gravity grease interceptors was a mystery for many years, since thePlumbing Drainage Institute (PDI) sized the units based on meals served per hour coupled with drain down time. Wastewater leaving the grease interceptor must not exceed 300 mg/L of oil and grease and 600 mg/L of solids. It depends on which model plumbing code applies to the installation. If there is no place to bury them outside they are often located in parking garages. A plumbing line upstream of grease interceptor. This installation is compliant with both the IPC and the UPC since it shows a trapped and vented fixture discharging through an approved interceptor without external vented flow control with a vent installed downstream. Units supplied with external flow restrictors are vented on the inlet . HyTSwoc [5laQIBHADED2mtFOE.c}088GNg9w '0 Jb meet cleaning requirements. Where to buy.

Metro Vancouver bylaw enforcement officers may inspect your grease interceptor and your maintenance records. Grease interceptors shall be constructed of durable, corrosion-resistant materials and shall have water-tight covers securely fastened in place. Plus, since our new president was just elected, nobody knows what we have in store for 2017 lets hope it is good! If the device serves only one fixture like a pot sink,it can often sit above the floor. Purchasing an interceptor prior to IW approval exposes the purchaser to risk of rejection and replacement costs. For engineered GGIs, specific models shall meet the following requirements: The goal for engineered GGIs is to closely comply to the concrete GGI requirements but allow slight flexibility if site conditions are not ideal for a concrete GGI. The Uniform Plumbing Code (UPC) does not permit a grease interceptor to serve as a fixture trap and also prohibits the installation of a vent between the air intake on the flow control and the grease interceptor.

If you use this chart, I would use the one-minute column, or your interceptor might be undersized. 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 two traps and their fixture drains can be either at the same level or at different levels, provided that they are on the same floor.

Or do you size it based on the number of fixture units connected upstream? I would size it as half the size of the inlet with a 2-inchminimum, but your AHJ might want you to use the connected fixture units so it is worth checking with your AHJ. 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. ?S]]__3`x~Mn-O_vW?o{W7W/NU/W|fw_qx-zfMSNgon>|~g^6/y%, #oi?

(1) Every oil interceptor shall be provided with 2 vent pipe s that, (a) connect to the interceptor at opposite ends, (b) extend independently to open air, (c) terminate not less than 2 000 mm above ground and at elevations differing by at least 300 mm, and (d) do not connect to each other or any other vent pipe. The above diagram would not be compliant with the UPC. 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. If you do provide a vent, how do you size it? . (8) Where an acid waste dilution tank is installed, it shall be provided with a vent pipe connected at the top of the tank and that is sized in accordance with Article 7.5.7.7. This is not compliant with the IPC since the code does not allow double trapped fixtures. 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. 1093 0 obj <>stream Drain down cant be controlled to two minutes due to the presence of air gaps on many of the fixtures. processes, meat packing and food processing facilities and similar processing You can ask Metro Vancouver to review your installation plan. 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. listed in rule 4101:3-15-01 of the Administrative Code. Most jurisdictions would say no because the interceptor is trapped internally. 6111.45 The purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens. serving chemical waste systems shall not be prohibited. This very simple concept allows two traps to be vented by the same vent. Our purpose is to serve and provide for our employees by being a resilient company that offers best-in-class products and services. 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. There are the large gravity grease interceptors, concrete for many years, but made of plastic in more recent years. 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. As waste water flows through a kitchens plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) The unit shown is certified to ASME A112.14.3 Type C (without external flow control) with a built-in or integral flow control and does not require an air intake. Hunters Curve doesnt work because it is intended for water flow rates, not drainage. The sizing of common venting is specified in Table 911.3. into a grease interceptor, the FOGS are intercepted or filtered out into a large underground holding tank. endstream endobj startxref Older service trucks have weaker vacuums, and theres no telling who will show up. %%EOF A grease interceptor or automatic grease removal device shall be required to receive the drainage from fixtures and equipment with grease-laden waste located in food preparation areas, such as in restaurants, hotel kitchens, hospitals, school kitchens, bars, factory cafeterias and clubs. 691 0 obj <>stream Once the grease interceptor reaches maximum capacity, a certified grease trap cleaning company will need to be called in order to service the grease interceptor. State regulations are updated quarterly; we currently have two versions available. To be honest, much of the confusion over whether a drawing shows a code compliant installation of a grease interceptor or not, can be the result of boilerplate drawings provided by manufacturers in submittals or installation instructions. If you dont know which fixtures are connected to a grease interceptor, call a plumber or other service provider to trace pipes back to the grease interceptor. 78. Some of these large interceptors (basically the plastic ones) come with vent connections on the tank itself. %PDF-1.6 % 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. Model plumbing codes require each fixture discharging into a grease interceptor be individually trapped and vented, and require the installation of a vent downstream of the grease interceptor. This checklist is provided as a reference tool and it is not intended to be exhaustive of all possible plumbing requirements. The vent on the flow control is an air intake. (a) in no case be less than 1 in. Most inspectors would say yes because the unit itself is trapped and a trap needs a vent, but if you ask the inspectors in Los Angeles City, they would say no, due to the fact that each fixture upstream of the trap is individually vented. a) All required grease interceptors shall comply with the following: 1) Material and Covers. 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; | Change settings.
