Grease Traps

Protect your kitchen from grease traps

Grease traps are an essential part of a restaurant or cafeteria’s sewer and drainage system. By keeping grease from going down your drains, you help keep your sewer line free of buildup and problems. Once a grease trap becomes full, however, it allows grease to enter the sewer system, creating build up that will eventually result in a clog or worse.

The Boston Water & Sewer Commission requires that grease traps be cleaned on a monthly basis or when they are 1/4 full of grease.

How we clean grease traps

Be wary of a service provider that simply dumps out the grease from your grease trap—it needs to be emptied AND cleaned to work properly. At John’s, we clean grease traps by hand. We also remove the dividers and snake the line EVERY TIME to make sure no clogs already exist that may cause problems later.

Many complexes and larger buildings may employ larger grease tanks to service their properties, rather than multiple smaller grease traps. We can also pump out and dispose of the grease in your larger grease tank. The contents of your tanks should be pumped out and disposed of on a regular basis, consistent with size, usage, and your city or town’s requirements.

Schedule regular grease trap cleaning

It’s not a matter of “if” you need grease trap cleaning, but when and how often. You can meet the city’s legal requirements and avoid business disruptions by scheduling regular cleanings. Whether your grease trap is 5 gallons or 10,000 gallons, we can create a custom preventive maintenance plan to meet your needs.

If you set up a preventive maintenance agreement with John’s, we will track your cleaning schedule for you. And we’ll work around your schedule by coming in early in the morning or late at night. This way, you can focus on making great food and serving your customers, and let us worry about your drains and grease traps.
