DIY Grease Trap: Step-by-Step Guide for a Squeaky-Clean Kitchen

Grease traps play a crucial role in preventing fats, oils, and grease (FOG) from entering wastewater systems and causing blockages and environmental damage. While commercial grease traps are readily available, constructing a DIY grease trap can be a cost-effective and rewarding project. This comprehensive guide will equip you with the knowledge and steps necessary to build a functional and efficient grease trap for your home or business.

Materials Required

• 55-gallon plastic drum or similar container
• PVC pipe (2-inch diameter)
• PVC elbow (90-degree)
• PVC tee (3-way)
• PVC end cap
• PVC cutter
• PVC glue
• Drill
• 1-inch drill bit
• Sealant
• Gravel
• Sand

Step-by-Step Instructions

1. Prepare the Drum

• Clean the drum thoroughly to remove any contaminants.
• Cut a 6-inch hole near the bottom of the drum for the inlet pipe.
• Cut a 3-inch hole near the top of the drum for the outlet pipe.

2. Install the Inlet Pipe

• Insert the PVC elbow into the inlet hole and secure it with sealant.
• Cut a length of PVC pipe to connect the elbow to the PVC tee.
• Glue the pipe to the elbow and tee.

3. Install the Outlet Pipe

• Insert the PVC elbow into the outlet hole and secure it with sealant.
• Cut a length of PVC pipe to connect the elbow to the PVC tee.
• Glue the pipe to the elbow and tee.

4. Install the End Cap

• Attach the PVC end cap to the remaining outlet on the PVC tee.

5. Create the Gravel Bed

• Place a layer of gravel (approximately 6 inches thick) in the bottom of the drum.

6. Add the Sand

• Fill the drum with sand to within 6 inches of the top.

7. Test the Grease Trap

• Connect the inlet pipe to your wastewater drain.
• Pour water into the inlet to test for leaks.
• If there are no leaks, the grease trap is ready to use.

Maintenance and Cleaning

• Regularly remove grease from the surface of the sand.
• Empty the sand and gravel and clean the drum every 3-6 months.
• Inspect the pipes and seals for damage and repair as needed.
