As a restaurant owner, you probably know that it is crucial to have a grease trap installed in your kitchen. Grease traps are designed to prevent fats, oils, and grease (FOG) from entering the municipal sewer system, which can cause serious environmental and health issues. In this article, we will discuss how to install and clean a grease trap properly to ensure it works efficiently.
Installing a Grease Trap
Before installing a grease trap, you need to determine the appropriate size of the unit. The size of the grease trap should be based on the size of your kitchen, the volume of wastewater produced, and the type of food preparation you do. Grease traps are available in various sizes and designs, including under-sink and floor models.
The installation of a grease trap requires professional expertise. You need to engage a licensed plumber to install the unit. The plumber will inspect your kitchen to determine the best location for the grease trap, based on the plumbing and drainage system. The grease trap should be installed close to the source of FOG, such as sinks, dishwashers, or ovens.
Once the installation is complete, the plumber will test the unit to ensure it is working properly. The plumber will also explain how to maintain the grease trap to prevent clogs and malfunctions.
Cleaning a Grease Trap
Cleaning a grease trap is essential to ensure it functions efficiently. The frequency of cleaning depends on the size of the unit and the volume of FOG produced. A small grease trap may require cleaning every week, while a large one may need cleaning once a month.
Here are the Steps to Clean a Grease Trap
Step 1
Turn off the power supply to the grease trap. If your unit has an automatic shut-off valve, it will stop the flow of wastewater into the trap.
Step 2
Open the lid of the grease trap. Use a shovel or scoop to remove the FOG layer from the top of the trap. Place the FOG in a container and dispose of it in a designated FOG collection bin.
Step 3
Use a grease trap cleaning agent to clean the interior of the trap. The cleaning agent will break down the remaining FOG and prevent the buildup of sludge. Follow the manufacturer’s instructions on the amount of cleaner to use.
Step 4
Use a hose to flush the trap with hot water. The hot water will help to dissolve any remaining FOG and flush it out of the trap. Make sure the water pressure is not too high to avoid damaging the trap.
Step 5
Close the lid of the trap and turn on the power supply. The trap will resume its normal function, collecting FOG from the wastewater.

Maintaining a Grease Trap
Apart from regular cleaning, there are several other steps you can take to maintain your grease trap:
- Scrape food scraps and other solids into a separate container before washing dishes or pots and pans. This will reduce the amount of solid waste entering the grease trap.
- Use a strainer or filter on sink drains to catch food particles and prevent them from entering the grease trap.
- Train your kitchen staff on how to use the grease trap properly. They should avoid pouring FOG down the drain and dispose of it in a designated FOG collection bin.
- Schedule regular maintenance and inspection of the grease trap by a licensed plumber to detect any issues and prevent malfunctions.
Installing and cleaning a grease trap requires proper knowledge and expertise. Engaging a licensed plumber is crucial to ensure your unit is installed correctly and functions efficiently. Regular cleaning and maintenance are essential to prevent clogs and malfunctions. By following these guidelines, you can ensure your grease trap works effectively and complies with environmental regulations.
