If you run a restaurant, commercial kitchen, or any food service business, installing a grease trap is essential for keeping your plumbing system clear and staying compliant with regulations. A grease trap helps separate fats, oils, and grease (often called FOG) from wastewater. Without one, these substances can clog pipes and cause costly repairs.
In this guide, we will walk you through the process of grease trap supply and installation and provide tips to ensure everything is done correctly. Whether you’re planning a DIY installation or hiring a professional, these steps will help you understand the process.

Why Is a Grease Trap Important?
Before we dive into the installation process, let’s understand why a grease trap is essential.
- Prevents Clogs: Grease and oil solidify when they cool, leading to blockages in pipes.
- Protects the Environment: By keeping grease out of the sewage system, you help reduce pollution.
- Compliance with Regulations: Many local authorities require food establishments to have a grease trap to meet health and safety standards.
- Reduces Repair Costs: A grease trap prevents costly plumbing repairs by keeping the pipes clear.
Now that you know why grease traps matter, let’s move on to the installation process.
Step 1: Assess Your Needs
The first step is understanding your business’s requirements.
How Much Wastewater Does Your Business Produce?
Determine the amount of wastewater generated in your kitchen daily. This helps decide the size of the grease trap needed.
What Type of Grease Trap Do You Need?
There are two main types of grease traps:
- Passive Grease Traps: Installed under sinks or near dishwashers; suitable for small kitchens.
- Interceptor Grease Traps: Larger units installed outside the building; ideal for high-volume operations.
Consider Local Regulations
Check with your local municipality for guidelines and requirements. This will help you choose a grease trap that meets legal standards.
Step 2: Choose the Right Location
Selecting the right spot for your grease trap is crucial for efficient operation.
Indoor Installation
If space is limited, consider installing a smaller grease trap inside the kitchen, usually under a sink.
Outdoor Installation
For larger systems, outdoor installation is preferable. Make sure the location is accessible for cleaning and maintenance.
Tips for Choosing the Best Location:
- Ensure the grease trap is easy to access for maintenance.
- Avoid placing it in high-traffic areas.
- Consider the slope of the pipes to ensure proper drainage.
Step 3: Prepare for Installation
Before starting the installation, gather all the necessary tools and materials.
Tools You May Need:
- Pipe cutters
- Wrenches
- Measuring tape
- PVC pipes and fittings
- Sealant and plumber’s tape
Materials Checklist:
- Grease trap unit
- Inlet and outlet pipes
- Vent pipes (if required)
- Concrete for outdoor installations (if needed)
Step 4: Install the Grease Trap
Follow these steps to install the grease trap properly.
1. Turn Off the Water Supply
Before you begin, shut off the water supply to prevent any leaks or spills.
2. Measure and Mark the Location
Use measuring tape to mark the positions for the inlet and outlet pipes. Double-check your measurements to ensure accuracy.
3. Cut the Pipes
Carefully cut the pipes to the required lengths using pipe cutters. Make sure the cuts are straight and clean.
4. Connect the Pipes to the Grease Trap
- Attach the inlet pipe to the grease trap’s inlet port.
- Connect the outlet pipe to the outlet port.
- Use sealant and plumber’s tape to ensure a tight, leak-free connection.
5. Secure the Grease Trap
For indoor installations, place the grease trap securely under the sink or designated area. For outdoor installations, you may need to pour concrete to secure the unit.
6. Check the Slope of the Pipes
Ensure the pipes have a slight slope (usually 1/4 inch per foot) to allow proper drainage.
7. Install Vent Pipes (If Required)
Some systems require vent pipes to prevent pressure build-up. Follow the manufacturer’s instructions for proper vent installation.
8. Test the System
Turn the water supply back on and check for leaks. Run water through the system to ensure it drains properly and that the grease trap is functioning correctly.
Step 5: Maintenance and Cleaning Tips
Proper maintenance is essential to keep your grease trap working efficiently.
1. Regular Cleaning
Clean the grease trap regularly to prevent clogs and odors. For small units, this might be weekly; larger units may need monthly cleaning.
2. Keep a Cleaning Schedule
Create a maintenance schedule to keep track of cleaning dates and ensure timely service.
3. Hire a Professional for Deep Cleaning
For larger systems, hiring a professional cleaning service is recommended.
4. Monitor FOG Levels
Check the levels of fats, oils, and grease in the trap. If the trap is more than 25% full, it’s time to clean it.
5. Inspect for Damage
Regularly inspect the grease trap for cracks, leaks, or other signs of damage.
Step 6: Ensure Compliance with Local Regulations
1. Keep Records
Maintain records of installation, maintenance, and cleaning to stay compliant with health and safety regulations.
2. Schedule Inspections
Some local authorities require regular inspections. Stay up-to-date with these requirements.
3. Follow Manufacturer Guidelines
Always follow the manufacturer’s instructions for installation, maintenance, and cleaning.
