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. 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. (3) Where a secondary receiver for oil is installed in conjunction with an oil interceptor, it shall be vented in accordance with the manufacturer's recommendations, and the vent pipe shall. 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-corrodiblematerials; Must be installed per ASME A112.14.3 Type D standard (indirect connection without external flow control); Must have a minimum liquid capacity consistent with the IW approval letter specified minimum; and. Here are a few examples. If your grease interceptor is undersized, you may be required to clean it out more often until you install a properly sized unit. Vy@ ggJ 1G0 V`JLX_HiNg` Tj 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. hbbd```b``5 )D/r`v&/A' ([bH0l-g3R ,> $^,$$ ?o 4} Grease interc eptors are installed on "gray" water drain lines and are designed to remove fats, oils and grease (FOG) from wastewater.

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.

This very simple concept allows two traps to be vented by the same vent. This drawing for a PDI G101/ASME Type A grease interceptor appears to be compliant with the IPC. If the device serves only one fixture like a pot sink,it can often sit above the floor. The grease interceptor (GI) must be constructed in accordance with the current plumbing codes adopted by the City of Austin, as amended, and installed in a manner acceptable to the Development Services Division (no exceptions); The GI shall have two compartments. You can ask Metro Vancouver to review your installation plan. Hydromechanical Grease Interceptors (HGI). The application of the referenced standards shall be limited and as prescribed in section 102.5 of rule 4101:1-1-01 of the Administrative Code.]. As waste water flows through a kitchens plumbing (3-compartment sinks, prep sinks, mop sinks, dishwashers, floor drains, etc.) 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. 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. The purpose of a grease interceptor is to catch and collect fats, oils, grease, and solids (FOGS) from commercial and restaurant kitchens. Enzymes, solvents, and emulsifiers are not permitted as they will only change the form of grease, allowing it to be carried out of the grease trap with the wastewater and deposited in the collection system. Purchasing an interceptor prior to IW approval exposes the purchaser to risk of rejection and replacement costs. If such is the case, they should be piped to the vent system and not left plugged, otherwise it may void the interceptor warranty. 1003.3.4 Hydromechanical grease interceptors, fats, oils and greases disposal systems and automatic grease removal devices.

Wastes from industrial It looks like your browser does not have JavaScript enabled. What's important to remember about AAVs is that they only allow for the relief of negative pressure in the drainage system. Some years ago, I was successful in getting a sizing table written in to Chapter 10 of the UPC relating fixture units to grease interceptor size, but the IPC still does not have such a table so it remains a mystery in that code. It can be done either way with dramatically different results. This bylaw applies to commercial kitchens and operations that prepare, package, serve, sell or otherwise handle food in a way that produces fats, oils and grease. Schierlocated in Shawnee, Kansasis a privately-owned, 100% USA-made manufacturer of a premier lineup of high-capacity, lifetime guaranteed grease interceptors for commercial kitchens. I would argue the former since, as noted above, each connected fixture is already trapped and the vent just serves to allow for the displacement of air it is not protecting a 1'' trap seal.

Many states that adopt or adapt the UPC have added an allowance for AAVs so you will have to check with your state to see if they are approved. Anyway, on to happier subjects. 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.
