Flow control devices for grease traps shall be installed on the ______________.

Flow control devices for grease traps are essential for managing the flow of wastewater into the grease trap, ensuring that it operates efficiently and effectively. The correct placement for these flow control devices is on the fixtures connected to the grease trap. Installing the flow control device here helps to regulate the volume of wastewater that enters the trap from various fixtures, such as sinks and dishwashers.

By controlling the flow at the fixtures, the device can prevent overloading the grease trap, which could lead to insufficient grease separation and potential sewer system blockages. This proactive approach not only enhances the performance of the grease trap but also facilitates proper treatment of fats, oils, and grease (FOG) before the wastewater is discharged.

Other placements, such as the inlet or outlet of the grease trap, would not be as effective because controlling the flow at those points does not address the variability of wastewater entering from different fixtures. Additionally, the service line is generally not a suitable location for these devices, as it would not effectively manage inflows from all contributing fixtures. Thus, the connection point at the fixtures is critical for optimal grease trap operation.
