Grease Traps vs. Grease Interceptors: Which Do You Need?

September 11, 2020 5:55 pm Published by Leave your thoughts

Grease traps and grease interceptors have one thing in common: they keep grease from destroying your plumbing as long as you regularly perform grease interceptor and grease trap cleaning in Strafford County, NH. However, they also have their differences, and even experienced restaurant owners and home cooks need assistance making an informed decision. Here are five differences to help you distinguish them and make the right choice for your needs:

  • Size: Grease traps are smaller and designed to hold anywhere from 10 to 500 gallons of grease. They are often the size of a bread box. Grease interceptors hold 500 gallons or more, and are the size of a mini refrigerator. Your ideal size is determined by how much grease your home or facility produces. The grease trap that works well for your home is likely not going to work at the popular pizzeria down the street.
  • Cleaning schedule: Grease traps are smaller, and require cleaning more often. Many busy restaurants clean their grease traps daily, and at least once a week is recommended. They can usually be cleaned by hand without calling in a professional. Grease interceptors are larger and hold more waste. They do not need cleaning nearly as often. They are normally cleaned once every three months, and always by professionals. There is no way to do it by yourself.  For both, the ¼ rule applies: if the trap or interceptor is ¼ full, it’s time to clean, even if the schedule time has not yet arrived. So, it’s better to get a trap or interceptor that’s too big rather than spend time and money constantly cleaning it.
  • Flow rate: Your facility’s flow rate determines which equipment works best. Grease traps work in low water pressure areas with a flow rate of less than 50 gallons per minute. They work well in homes and smaller boutique-type cafes. Grease interceptors are designed for high-volume flow of more than 50 gallons per minute. Large facilities like busy restaurants and hospitals usually require grease interceptors.
  • Installation area: Both grease traps and interceptors emit foul odors, so the location of installation is important. Grease traps, being smaller, are installed under a sink. Since it can smell bad, that becomes another reason to clean it frequently. Grease interceptors are installed outside or underground, depending on what is allowed by local ordinances. If you buy an interceptor, keep it away from spots where customers eat and socialize. Otherwise, your Yelp reviews may suffer.
  • Material: Grease traps are manufactured from steel, plastic, fiberglass and PVC. If they rust, they are done for, and it’s time to replace them. The same is true if they crack or break. Grease interceptors are designed to withstand outdoor conditions. They are made from cement, PVC or fiberglass.
