Understanding the Importance of Proper Grease Trap Sizing
Choosing the right grease trap size is key for commercial kitchens in the UK. It’s not just the law; it helps prevent clogs and backups in drainage systems. The right size ensures efficient wastewater management and follows local rules.
Compliance with Regulations

| Grease Trap Size (GPM) | Kitchen Size (Sq Ft) | Drainage Fixture Units (DFU) |
|---|---|---|
| 20 | Up to 1,000 | Up to 21 |
| 35 | 1,001 to 2,500 | 22 to 35 |
| 50 | 2,501 to 4,000 | 36 to 50 |
Knowing how to size proper grease traps helps UK commercial kitchens follow the law and keep their drainage systems working well. This avoids big costs and protects the environment.

Calculating Grease Trap Capacity Requirements
Finding the right grease trap size is key to keeping your commercial kitchen’s plumbing clear of clogs and backups. The capacity of a grease trap depends on the maximum rate of flow it can handle. This flow rate changes based on your kitchen’s setup.
To figure out the right grease trap size, think about these important points:
- Number of drainage fixtures: Count sinks, floor drains, and other fixtures that send grease into the trap.
- Anticipated flow rates: Guess the highest flow rate (in gallons per minute) your kitchen can reach with its fixtures.
- Local regulatory requirements: Make sure the trap you pick meets your area’s plumbing code standards.
By looking at these factors, you can find the right grease trap size for your kitchen. This careful planning stops plumbing problems and keeps your business in line with the law.
| Fixture Type | Flow Rate (GPM) |
|---|---|
| 3-Compartment Sink | 20 GPM |
| Dishwasher | 15 GPM |
| Floor Drain | 10 GPM |
Knowing how to calculate the capacity of a grease trap and the maximum rate of flow through a grease trap helps your kitchen’s plumbing manage grease well.

Types of Grease Traps and Their Advantages
Choosing the right grease trap is key to managing kitchen grease and avoiding plumbing problems. Let’s look at the different types of grease traps and their benefits. This will help you pick the best one for your commercial kitchen.
Hydromechanical Grease Traps
Hydromechanical grease traps are small, fitting under sinks in smaller kitchens. They use flow control and mechanical baffles to separate grease from water. Their big plus is easy installation, fitting into current plumbing without big changes.
Gravity Grease Traps

Automatic Grease Traps
Automatic grease traps use tech to remove grease on their own. They have sensors and mechanisms to keep grease out. The big plus is they work without needing constant attention, saving time and money in busy kitchens.
| Grease Trap Type | Advantages |
|---|---|
| Hydromechanical | Compact size for easier installationSuitable for small to medium-sized kitchensRequires less maintenance compared to gravity traps |
| Gravity | Handles higher flow rates and grease outputSuitable for larger commercial kitchensSimple design with fewer mechanical components |
| Automatic | Automated grease removal processReduces the need for frequent manual maintenanceSuitable for high-volume commercial kitchens |

Maintenance and Cleaning of Grease Traps
Keeping a grease trap clean is key to its efficiency and avoiding backups and bad smells. How often and how you clean it affects its performance and life span.
Frequency and Methods
Experts say you should clean a kitchen grease trap every 3 to 6 months for best results. But, the right time can change based on the trap’s size, how much grease and food waste it gets, and how often it’s used.
To stop a commercial grease trap from smelling, cleaning it often is a must. Cleaning involves these steps:
- Turn off the power to the grease trap, if it has electricity.
- Take off the lid or cover and check inside for any grease or blockages.
- Use a wet/dry vacuum or a grease trap pumping service to get rid of the grease, solids, and liquids.
