How to Install a Grease Trap

Guide
Table of Contents

Grease traps are used in restaurants and other food service facilities to trap oil, fat, grease and wax so it doesn't move on to the sewage system and create blockages. Understanding the proper step-by-step process of a grease trap installation is important for the health of your restuarant.

Grease traps are found in restaurants where they are used to get rid of oil, wax, fat, grease and various other debris that falls into the sewage system and can cause blockages. It is a simple device, but it delivers a ton of service. It is required by law at commercial cooking facilities such as catering operations, cafeterias, restaurants and other food service facilities.

The grease trap needs to be easily accessible so it can be cleaned out. You can hire grease rendering companies to collect the grease which may subsequently be used in the making of soap and pet products. A grease trap in a commercial setting such as a restaurant needs much more frequent cleaning than one in a private home.

So how do you go about completing a grease trap installation?

Grease Trap Setup Installation

The first step in a grease trap installation is to figure out where you want to install the grease trap. You have a lot of options but the area has to be large enough for the grease trap to fit. To get an idea of how it works, consider that the grease trap is fairly large and shaped like a square box with the capacity to hold up to 40 liters of water. It should be cleaned out at least once every two years, though the exact frequency of cleaning will depend on how often it's full. Most often, grease traps are installed under the sink. You should use a cleanout tee before attaching the grease trap to the vent.

Connect the Grease Trap

Connecting the grease trap is a simple process if you understand the instructions that come with the grease trap. Each of its three connections – upper right, left and bottom right – is attached to a different correlating part of the sink. It's crucial that you attach each to the correct part, or your grease trap won't function properly.

Upper Right Connection

The upper right connection is attached to the vent of the holding tank of the grease trap. It is the connection that controls how water flows in and out of the trap. You should clean out the vent with a tee before making the connection.

Left Connection

The left connection is connected to the pipe of the sink. This pipe is the one that comes down from the sink. It loops up and joins another straight pipe. It is the looping pipe that you will attach to the left connection of the grease trap.

Bottom Right Connection

The bottom right connection is attached to the sewer pipe. It is the pipe that directs the liquid in the grease trap to the sewage system.

Maintenance of Your Grease Trap

You’ll want your grease trap working efficiently and lasting as long as possible between cleanings. To do that, run some hot water in the sink as soon as some greasy food or liquid goes down the drain.
