Grease Trap Maintenance Is Critical!

Parrish & Sons will schedule regular maintenance and keep You code compliant

It is a code violation for commercial accounts to operate a food service establishment with a malfunctioning or full grease trap/interceptor. Inspectors actively enforce this important code provision.

A grease interceptor overflow or spill that discharges / Overflows into a storm drain will result in costly clean-up and BIG fines from your local municipality.

The most common cause of sewer line failure for foodservice establishments is grease. Clogging of sewer pipes and drain lines are common consequences of oil and grease in wastewater. The best way to avoid this problem is to prevent oil and grease from getting into the sewage system in the first place! This must be done by separating the gray water (kitchen wastewater) from black water (restroom wastewater) by installing a grease interceptor or grease trap to process the gray water and capture the grease.

A grease interceptor looks very much like a septic tank. Sinks, dishwashers floor drains and similar fixtures discharge their wastewater through a separate plumbing stub out into a grease interceptor. Grease interceptors are typically sized from 7500 gallon to 10,000 gallons 12000 gallons is a typical size grease trap.

Upon entering the interceptor the wastewater flow slows which allows the lighter grease to separate from the wastewater and float to the top of the interceptor where it cools. The grease will collect and float in the interceptor. And, over time the grease will build up to a point where it needs to be removed. If not removed the grease will work itself into the sewer system.

Once grease enters the drain lines it will clog them and cause failure of the system This can create problems for your establishment and others down the line from you and is a big problem for City maintenance crews and will cost far more to correct than initial proper maintenance.

Grease Management

The grease interceptor should be checked daily or weekly depending on the business and the grease thickness measured. This can be done with a simple measuring rod If the grease layer is 1/4 the thickness of the entire trap/interceptor the grease must be removed by an approved method.

Parrish & Sons Recommends that commercial establishments with grease trap interceptors consider our maintenance program.

Regular maintenance consisting of routinely checking the grease level and periodically pumping the tank. When the grease oil layer exceeds 1/4 of the tank capacity it should have already been pumped. The threat of stoppages spills and environmental degradation increase drastically at this point.

Therefore grease trap interceptor maintenance becomes a very important aspect of foodservice management. Excess food or grease from meal preparation should never be dumped into a sink grease trap interceptor or any other part of the plumbing system. Neglected grease traps may also cause serious problems in the City sewer system.
