Frequently Asked Questions (FAQs)

1. What size grease trap do I need for a commercial kitchen?

The size of the grease trap for a commercial kitchen should be rated twice the flow rate. For example, if the grease trap's capacity is 40 pounds, the incoming flow rate should be 20 GPM (Gallons/Minute). This ensures that the grease trap can effectively handle the amount of grease and waste generated by the kitchen.

2. How much does it cost to build a grease trap?

The cost of building a grease trap can range from $1,000 to $5,000, depending on factors such as the size and complexity of the unit, as well as the installation process. It is important to consider these costs when planning for the installation of a commercial grease trap.

3. How big are restaurant grease traps?

The size of a restaurant grease trap can vary depending on the flow capacity it needs to handle. For example, a three-compartment sink may require a grease trap with a capacity of 70 to 90 pounds to handle the maximum flow rate. The size of the grease trap should be appropriate for the specific needs of the restaurant.

4. Can a grease trap be too big?

While it is important to have a grease trap that can handle the flow rate of the kitchen, getting a grease trap that is too big may not necessarily be beneficial. The maximum flow rate that a grease trap can handle depends on its design and size. It is important to choose a grease trap that is appropriate for the specific needs of the kitchen.

5. How far can a grease trap be from the sink?

Grease traps should be installed at a minimum distance of 10 feet from sinks and dishwashers. This allows for adequate cooling of the wastewater before it enters the grease trap. Additionally, the water temperature should be less than 120 degrees Fahrenheit prior to entering the grease trap.

6. Can I install my own grease trap?

Unless you have experience as a plumber, it is not recommended to install your own grease trap. Improperly installed grease traps may allow fats, oils, and grease (FOG) to escape into the sewer, potentially causing clogs. It is best to hire a professional plumber to ensure the grease trap is installed correctly.

7. How much does it cost to install a 100-gallon grease trap?

The cost of installing a 100-gallon grease trap can vary depending on factors such as location and specific requirements. On average, the installation cost for a small grease trap (0-100 gallons) ranges from $250 to $1,500. For larger grease traps (750-1,500 gallons), the average installation cost is between $4,000 and $8,500. Grease recovery devices can cost between $3,500 and $6,000.
