The GI-14 grease trap from Atlantic Metalworks is a carbon steel grease interceptor certified by the Plumbing and Drainage Institute and capable of handling a drain flow of 7 gallons per minute. With a holding capacity of 14 lbs, the GI-14 is a good fit for many single compartment sinks; but, since multiple factors affect sizing, your local health & plumbing requirements will be the final rule. Hydromechanical grease interceptors like the GI-14 depend on a simple yet effective baffle system that enlists agitation and Bernoulli's principle to separate fats and oils out of the water and lift them to holding area. This keeps excess grease in your waste water from washing into your drainage pipes where it can clog your system and cause expensive plumbing issues. Speaking of guarding against expense, Atlantic Metalworks grease traps fit the two rules of thrift: 1) Don't pay too much 2) Buy something solid. Constructed of heavy carbon steel, these traps are anything but flimsy and their corrosion-resistant enamel coating helps guard against rust. As to price, a smart shopper like you already knows the GI-14 is one of the most affordable grease interceptors you can buy.

  • Capacity: 14 lbs.

Atlantic Metalworks GI-14 -14 lb 7 gpm Grease Trap Interceptor is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Perfect fit and it sits off the floor. It will be years before I can really tell how this unit holds up, but I can say that it fit perfectly in the extremely limited space under my pot sink. It replaced a unit that had rusted out because it sat directly on the floor. This unit sits slightly above the floor. This will allow the area to stay drier. Our maintenance crew said it was a breeze to install.

my plumber says I need a 10 gal capacity, with a minimum flow rate of 4 gal per minute, with 2 inch inlet and outlet. Do you sell one? Can I go to greater capacity your 14 - 8, 2 inch.

Asked by: jbbeasley
When it comes to the flow rate, being sure to reach the minimum flow rate is what counts. It's fine to go over your minimum, as this won't adversely affect your performance in any way. Note: when thinking of grease trap capacity, keep in mind that we measure capacity by how many pounds a unit can hold and how many gallons a minutes it can process. Our grease traps will do half as many gallons a minute as it holds in pounds (e.g. a 70 pound unit will take 35 gallons a minute; a 40 lbs. unit will do 20 gallons). So if you need a 10 gallons a minute unit, you will probably want to consider the GI-20 or GI-30. If you need a 10 pound capacity, our GI-14 would suffice.

if water is coming out of the dish machine over 160 degrees grease is melted any way how is it going to give time to solidify the grease and stay in the tank preventing from getting into the sewer system????

Asked by: orchard86
That's a great question. There are two main schools of thought when it comes to answering this question. Different municipalities have different answers, so it's extremely important to see what your local code requires. The first thought is to offset the grease trap far enough from the dishwasher so that it cools below 120 degrees and the water and FOG (Fats, oils and grease) separate before hitting the grease trap. Usually this would mean having somewhere between 10 and 20 feet of pipe between the grease trap and your sinks / dish machine. Other codes require larger grease traps so that the water cools in the grease trap, rather than before it. The idea here is that the room-temperature water in the grease trap will mix with the hot water, cooling it and separating the water from FOG. Plus, since it is a larger trap, it will take the water longer to make its way though the trap, so it has a longer time to cool and separate. My advice is to check with your local inspector and/or a licensed plumber to see what is required in your area. It will likely be one of these two solutions, but if you find something different please let us know.

I am looking at a grease trap, Gl-14. I need to know if this can be installed inside the building and under the sink. If not, do you have one that can be used inside, at the same price as Gl-14

Asked by: Granny
These Atlantic Metalworks grease traps are designed to be installed inside and above ground. Most people do put them right under the sink and out of the way. Just be sure to check with a local plumber or the health department to make sure you are getting a size that meets the local requirements.
