Understanding grease traps and their importance
Grease traps are also called grease interceptors. Grease traps are devices that may be installed in a plumbing system and capture FOG before the sewer line is reached. They allow only water to pass through while letting all the grease and other solid materials stay inside the compartment.
The most common places where trap installation is done include restaurants, food processing facilities, and institutional kitchens. Buildups of FOG quickly become causes of plumbing issues and contamination of the environment in commercial establishments.
If not installed in the right way, FOGs from grease trap may accumulate in the plumbing system leading to blockages, unpleasant odor, and cost repair. Moreover, environmental agencies and health departments require using grease traps to minimize pollution and ensure water systems. By installing and maintaining a grease trap, the businessman ensures a clean environment and secures his business venture.
Step-by-step guide for grease trap installation
Step 1: Assess your need
1. Determination of Size and Type
There is a wide range of grease interceptors on the market. Most decisions about their size depend on the amount of water that flows out from the given establishment, coupled with the FOG that is expected to come out from that place. Highly busy kitchens, including high-traffic restaurants, require the installation of automatic grease traps.
2. Choose the Location
The location should be good; the closer to the source of wastewater, the better because FOG cannot cool and harden in pipes. It should also be easily accessible in case maintenance was to occur since grease traps should be cleaned often.
| Establishment Type | Recommended grease trap Size |
| Small Café or Bakery | 20-40 gallons per minute |
| Medium Restaurant | 50-75 gallons per minute |
| Large Restaurant or Hotel Kitchen | 100-150 gallons per minute |
Step 2: Prepare for installation
1. Gather Materials and Tools
Before laying such grease traps, materials will be obviously in demand, including pipe, fittings, gasket, and seal.

Step 3: Install the grease trap
1. Shut Off the Water Supply
Turn off the water supply in the installation area to avoid any accidental leaks or spills during the installation process.
2. Excavate the Area (if necessary)
For outdoor installations, you may need to excavate a portion of the ground to accommodate the grease trap. Ensure that the excavation is deep enough for the trap and allows proper drainage.
3. Position the Grease Trap
Place the grease trap at the designated location. Use a level to ensure the unit is stable and positioned correctly, as uneven installation can lead to inefficiencies or leaks.
4. Connect Inlet and Outlet Pipes
Attach the inlet pipe at the grease trap’s side where water being used to enter, while the outlet pipe that connects the other side gives treated water the way towards the sewer line. They should be tightened and sealed at the point with gaskets and sealants to eliminate any leak.
5. Seal Connections
Proper sealing is crucial for effective grease trap installation. Any leaks at this stage can lead to operational issues and potentially costly repairs.
6. Install a Vent Pipe
Adding a vent pipe helps prevent the buildup of gases within the grease trap, reducing odor and ensuring safe operation.
Step 4: Test the Installation
1. Restore the Water Supply
After completing the grease trap installation, turn the water supply back on. Run water through the system to check for any leaks or issues with flow.
2. Inspect for Leaks
Examine all seals and connections to ensure there are no leaks. Tighten connections or reseal areas as needed.
3. Test Functionality
Verify that the grease trap is effectively capturing FOG, allowing only water to flow into the sewer system. This test is essential to ensure your grease trap installation is effective.
