The Watts WD-15 30 lb. grease trap prevents greasy substances from entering plumbing systems, septic fields, and waste water treatment facilities.

Greasy substances easily enter areas, such as septic fields, where they cannot be processed properly and could harm the environment. Grease traps like the Watts WD-15 are often used with cooking or prep sinks, pot sinks, and commercial dishwashers in various types of commercial food service operations. These traps block the harmful substances from entering areas where they can't be processed, making for more efficient systems and a cleaner environment.

The Watts WD-15 grease interceptor is built to last, with a body made of 11-gauge cold rolled steel. The removable grease accumulating cover and baffle assembly are secured to the grease trap's body with a center mounted hex head and a gasket seal.

2" Inlet and Outlet

For convenient operation, this unit features a 2" inlet and outlet. An external cast iron flow control fitting is also included.
