Many people use cooking oil to prepare food, which often ends up going down the drain. Although oil easily flows down the drains in its liquid state, it becomes a headache when it hardens upon cooling and clogs the pipelines. You can prevent this problem by installing a grease trap. Here’s a closer look at this plumbing device.

What Is a Grease Trap?

A grease trap, technically known as a grease interceptor, catches and removes grease, fats, oil, and solids in the wastewater before flowing into the disposal system. It is often installed between the kitchen drain lines and sewer pipes to collect the grease and keep it from entering the sewer system.  

The trapped grease and solids then sink to the bottom and form thick sludge over time. Periodic emptying or cleaning of the buildup is crucial for maintaining the trap’s efficiency and functionality.

There are two types of grease traps—hydromechanical and gravity. A hydromechanical grease interceptor usually sits under kitchen sinks and cleanup areas, using a system of baffled chambers to separate the grease from the water before it flows through the fixture.

A gravity grease interceptor relies on the fact that oil, being lighter than water, will float to the surface. This type is generally situated underground outside an establishment and uses a large holding tank of water to accept incoming grease. This method requires sufficient time for the grease and water to sit idly and separate. 

Why You Need It

The primary purpose of a grease trap is to keep your sewer pipes in excellent condition. Grease and solids can cause blockages in the lines, resulting in slow-moving drains, unpleasant smells, and unsanitary sewage backups. 

However, the benefits of an efficient trap go beyond your property. It also helps the city or municipal sewer system by reducing the amount of grease flowing into it and the risk of sewage overflows. That’s why installing one is a building code requirement, especially for foodservice businesses.

How to Maintain It

Given the impact grease can have on municipal sewer systems, you could face hefty fines for disposing of it improperly. Some people attempt to clean the trap on their own, but most end up doing a haphazard job of it. 

It's best to maintain your commercial grease trap by scheduling regular pumping every three months with professionals to save time and effort and avoid possible fines. They are equipped with the correct tools and training to do the job efficiently. For household grease traps, the cleaning interval will depend on how quickly the trap fills with fats, oils, and grease. A general rule of thumb is to have it cleaned once grease has accumulated to one-quarter of the tank's capacity.
