Ashland 4850 Details

The Ashland PolyTrap 4850 100 lb. grease trap with threaded connections prevents greasy substances from entering plumbing systems, septic fields, and wastewater treatment facilities where they cannot be processed properly and could harm the environment. This grease trap is different from traditional metal grease traps since it is made of a durable, seamless polyethylene material that will not rust, corrode, leak, or leach. It is also lighter weight and easier to handle than heavy metal grease traps so it is less demanding to install.

Grease traps are often used with cooking or prep sinks, pot sinks, and commercial dishwashers in various types of commercial food service operations. This model includes a flow restrictor that fits on the inlet side of the interceptor and slows incoming wastewater, redirecting it through the scientifically-placed, removable baffles inside the grease trap.

The lid of this grease trap features a D-ring sealing gasket and is secured with flush mounted bolts. The grease trap comes equipped with complete inlet and outlet connections with standard female threads.

The grease trap has a grease capacity of 100 lb. and a 50 GPM flow rate.

Wasn't overly impressed with this product. Even though it was installed by a professional, within a month in it was leaking from the bottom. I contacted the manufacturer within the warranty's time frame. I sent pictures as requested and never received another response to resolve the issue. We had it removed and installed a better product.

Thank you for your feedback! We’re sorry you did not prefer this product. For recommendations, please contact our Customer Solutions team.

Plumber said this is the nicest trap he has ever installed. Easily removable top and baffles for cleaning. The stainless screws and built in seal keep everything in nice.
