Whether you are replacing a grease trap or purchasing a new one, think about the factors described below to become a grease trap expert.

1. Get the right size

The first thing to do is decide on the size of grease interceptor and the number of sinks you need. It’s important to get the right size. If it’s too small, your wastewater will flow away too quickly; if it’s too big, you’ll waste money. A Gallon per Minute (GPM) measurement can help you find the perfect size.

2. Anticipate sink usage

Your menu affects the size and working of your grease trap. If your commercial kitchen produces a lot of fat and grease to be thrown down the sink, you will need a bigger model. You should also calculate how many meals are made and the amount of waste sent down the sink.

3. Cost of installation

Additional expenses after purchase include emptying the unit, disposing of the waste, professional help and maintenance, all of which can be costly.

Automatic grease traps require less maintenance, and high-capacity grease traps need less frequent cleaning, therefore saving money.

Increasingly, kitchen grease is being recycled to create biodiesel. You could get discounts by disposing of material with a local biodiesel plant.

4. Parts availability

Grease interceptors are made up of many different components that have to cope with grease, food waste and hot water. At some point in time, they will need replacing.

Before buying, find out how easy and fast it is to get the necessary parts. Ask manufacturers and dealers about their availability. You need to know how regularly replacements will be required.
