How Often Should You Pump Your Grease Trap?

February 24, 2023

One of the most common questions asked by commercial kitchen operators is “how often should I pump my grease trap?” The answer to this question depends largely on your restaurant’s specific needs and your local municipal regulations.  

Over time, fats, oils, and greases (FOG) begin to build up in your grease trap. As this amount of grease begins to accumulate, it can start forming a thick layer in your grease trap. This accumulation can lead to clogs and backups in your sanitary sewer lines. It can also result in a toxic and noxious odor that is unhealthy for your customers, employees, and the environment. The most common indicator of when your trap needs to be pumped is when FOG makes up a quarter of its volume. This is called the “25 percent rule.” That said, if your FOG layer is 5 to 6 inches in a large grease trap and 2 inches in under-sink traps, you’re likely due for pumping.. 

The standard rule of thumb is to have your grease trap pumped every 1 to 3 months, depending on the size of your establishment. A well-maintained grease trap is a must for any commercial kitchen. It can reduce clogs and downtime in the kitchen while helping keep your bottom line happy. If you’re not keeping up with this important task, you could be putting your business at risk of a fine or worse, a costly sewer repair.
