The Watts 40 lb. low profile 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 low profile design is ideal for low clearance applications.
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 40 lb., and a flow rate of 20 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.

This economy mid size grease trap is a good value. Thread fitting was a little off but my plumber was able to make it work.
This grease trap is great for the size and price! Have had it for a few years and only have had to change the gasket once Great for a restaurant to avoid grease going out and potentially causing a extra expense.
If I could leave 10 stars, I would! When we bought our commercial kitchen, the current trap constantly overflowed. This new one was a breeze to install and has been a game changer for us.
Great grease trap for all the flatware sanitation executives out there! What I like is that it has a compact size yet the capacity is up to cade in our area. It seems to be very well built and actually looks good for what it is. Plumber said installation was straight forward and easy. Recommended! Cheers! Chef Tony
Was very simple to install. Is easy to clean and very good price. This is painted with non corrosive paint, this help to keep the rust away
This piece was an exact replacement of what I had in my restaurant. The swap was easy and the box contained all the parts I needed to finish the job. I am happy with the quality looks like all the welds are solid and should last me many years.
This larger grease trap does a fantastic job. I was amazed at how fair the shipping cost was, even though it weights over 80 pounds.

Grease Trap - I didn't want it, but if you have a kitchen, you will probably need it. Plumbers installed with ease. Haven't had to change it yet.
