Watts WD-4-THD Details
The Watts 8 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 unit has a flow restrictor on the inlet side of the interceptor that slows incoming effluent and redirects it through baffling inside the grease trap. As the flow is gradually slowed, lighter than water substances accumulate inside the trap above the static water line.
This grease trap features a body constructed of 11-gauge cold rolled steel with an oven-cured, acid-resistant baked gray epoxy coating. Other standard features include a solid steel cover with gasket, a removable baffle assembly, a deep seal trap with cleanout, threaded connections, and an external cast iron flow control fitting (flow restrictor). This unit has a grease capacity of 8 lb., and a flow rate of 4 GPM. It is PDI (Plumbing & Drainage Institute) certified, and meets the industry and PDI Standard PDI-G101 for separation efficiency. This standard specifies that the grease trap must maintain 90% separation efficiency up to its rated grease retention capacity.

My only complaint- one side was threaded wrong. However we still made it work. It’s the perfect size for our food truck! The price is great compared to others. It is heavy though.

We just installed this grease trap and it seams to be working well. The flow reducer is a bit much and the basins take a while to drain. I opened it once it is definitely intercepting grease.

My plumber loved this. Easy for him to install. It came with all the parts so there was nothing extra for him to purchase. It is perfect size for my bakery. Does not take up a lot of room and easy lid to remove.
