Drainage, Waste & VentQuestion 145 of 360
The size of a hydromechanical grease interceptor is primarily selected based on…
a.the flow rate (GPM) of the fixtures it serves and its rated grease retention capacity
b.the color of the discharge
c.the length of the drain line only
d.the number of restrooms in the building
Explanation
A hydromechanical (point-of-use) grease interceptor is selected by the flow rate in GPM it must handle and its rated grease capacity in pounds. A flow-control fitting limits flow to the rated GPM so grease can separate. Undersizing lets grease pass straight through to the sewer.
