Grease Traps: Why You Need One

1 Comment

What is a grease trap and why do I need one? 

A grease trap, otherwise known as a grease interceptor, does just what the name says — traps/intercepts grease. It’s common knowledge that pouring fats, oils, and grease down the drain is a really bad idea. Doing so can not only clog the drain, but it can further damage pipes, sewer lines, and more. It creates a very messy and expensive problem you just don’t need.

At home, grease can easily be disposed by emptying it into a jar and putting it in the trash. However, for commercial kitchens that see a lot more grease than just one jarful, a different process is in order. This is where grease traps come into play. According to the experts at PlumblingSupply.com, “A grease trap works by slowing down the flow of warm/hot greasy water and allowing it to cool. As the water cools, the grease and oil in the water separate out and float to the top of the trap. The cooler water – minus the grease – continues to flow down the pipe to the sewer.” This quote accurately, and simply, defines the function of a grease of a trap. 

What are the different types of grease traps and how do I know which one to buy?

For starters, grease traps generally come in smaller and larger versions. Smaller versions can connect individually to your sink; whereas larger interceptors are placed outside and underground — these larger interceptors are built to service entire establishments. So, when determining what size grease trap to get, think first about how much grease and oils your establishment sees on a daily basis. PlumbingSupply.com says that the size of an interceptor is “tied to the rating for maximum allowable flow in gallons per minute.” Most experts say there are three ways to determine the flow and proper size: “sizing according to the waste pipe’s diameter, sizing according to the total volume of draining fixtures, or sizing according to Drain Fixture Unit values (DFU), which are defined for specific fixtures by the Uniform Plumbing Code.” For further information on how all this works, check out this informational article here.

A few things to keep in mind: 

Remember, if the interceptor is too small, grease will pass through freely. If the interceptor is too big, sulfuric acid colt potentially be created. To avoid further maintenance and extra cleaning, its best to first talk with the manufacturer or an expert.

  1. Thank you for these tips, Al! There’s definitely a myriad of factors to consider when installing a grease trap. Having the choice of a below or an above ground interceptor gives so much more flexibility to cater for existing drainage infrastructure while still making better environmental decisions. I came across ACO’s range of grease traps, which look very versatile: http://www.acopassavant.com.au/en/aco-news/the-perfect-fog-solution-for-restaurant-owners/
