What Does My Grease Trap Do?

Posted by ADB Septic on February 12, 2019

Shrug-minIn short, your grease trap traps the grease from your kitchen to keep it from clogging up your plumbing. Grease traps are an essential part of restaurant kitchens, as they keep your plumbing in good working order and prevent health code violations. When you keep up with your grease trap maintenance, it’s also helping keep your employees and customers happy and healthy. If you’re interested in learning more about your grease, trap we’ve compiled the important information you need below.

Why Does My Restaurant Need a Grease Trap?

Grease traps are important because they catch the fats, oils, and grease from your cooking. If these materials go down your drain, they can clog your pipes and your sewer line. If these pipes get clogged, they can cause unsanitary flooding which will lead to expensive repairs and health hazards. Because restaurant kitchens produce such large volumes of grease when cooking, grease traps are important to keeping the kitchen functioning properly.

How Does it Work?

Grease traps function by catching fats, oils, and grease, while separating them from wastewater and solid food. The wastewater goes through restaurants’ 3 compartment sinks and dishwashers and into the grease trap.

Grease Trap Container

The grease trap container captures wastewater that goes through the sinks and acts as a reservoir. As the wastewater cools, fats, oils, and grease harden. The grease are lighter than water and float on top. Wastewater is then forced through the crossover pipe while the greases and solid foods remain in the container.

Crossover Pipe

After the majority of solids have been removed, the water flows through the crossover pipe. This pipe provides the wastewater with a secondary filtration, removing the majority of the solids from the water. Once the wastewater is filtered through the crossover pipe, it can travel to the outgoing line.

Outgoing Line

The outgoing line is responsible for dispelling filtered water into the sewer system. It is designed to allow the grease trap to maintain its liquid level. A proper liquid level is essential to ensuring that the grease trap continues to separate solid foods, grease, and water.

How Often Should My Grease Trap be Pumped?

Your grease trap container will hold grease and solid foods that will build up over time. For this reason, it’s important to regularly pump your grease trap to remove this sludge. In order to ensure proper functioning, you should pump your trap when the food and grease takes up 25-33% of the trap. In general, restaurants pump their grease traps roughly once a week, however, there are multiple factors that will impact the frequency at which your grease trap needs to be pumped.

Size of the Trap

If you have a very large grease trap, it might need to be pumped less often because it will take longer to fill. The size of the trap will affect the frequency at which you need to pump your grease trap.

Amount of Food

The amount of food prepared in your kitchen will impact your pumping schedule as well. During a busy period or season, you’ll need to pump your grease trap more often to keep up with the grease buildup. During slower periods, you can pump your trap less frequently.

Type of Food

The type of food cooked in your kitchen can contribute to a more or less frequent pumping schedule. If your restaurant cooks greasier food frequently, it will probably need to be pumped more frequently. Although all restaurants produce grease, fats, and oils, those who cook large volumes of fried food or other greasy foods will need more frequent grease trap pumping.

Cleaning Practices

When you scrape dishes before you wash them, you will keep extra food and grease out of the drain, decreasing the frequency at which your grease trap will need to be pumped. You should also avoid pouring higher fat liquids, such as fryer oil, down the drain when possible
