A floor drain with interceptors for grease, oil, and solids requiring a 2" trap is equivalent to how many units?

In plumbing, a floor drain equipped with interceptors designed to capture grease, oil, and solids serves as an essential component in maintaining the integrity of waste systems, especially in commercial establishments like restaurants or kitchens. The term "units" in this context refers to the drainage fixture units (DFUs), which are used to determine the load that the drainage system can handle.

When a floor drain is specified with interceptors and requires a 2-inch trap, it reflects a higher capacity to manage waste compared to standard drains due to its added functionality. According to plumbing codes, particularly the Uniform Plumbing Code (UPC) and the International Plumbing Code (IPC), a 2-inch floor drain with these specific attributes typically assigns it a drainage load of 3 fixture units.

This classification significantly helps in the sizing of drainage piping, ensuring that the system can effectively handle the flow of wastewater and prevent blockages or overflows. Hence, understanding that a 2" trap in this context equates to 3 units aids plumbers in designing appropriate waste systems that comply with plumbing standards and promote efficient waste management.
