Fats, oils and grease leave a kitchen as hot liquid and harden as they cool in the pipe. A grease trap or interceptor slows wastewater down long enough for grease to float and solids to settle, so only cleaner water continues to the sewer. When the trap is full, undersized or damaged, grease moves on and coats the line downstream until it closes off.
Small grease traps usually sit under or near the sinks. Larger grease interceptors are in-ground tanks outside the building. Both need regular pumping by a licensed grease hauler, and both have parts that wear out: baffles, outlet tees, lids and gaskets. Food service businesses in Stockton fall under the city's grease control requirements, which include keeping the trap maintained and the records to show it.
We handle installation, replacement, repairs and the lines in and out of the trap. For lines that keep closing up, hydro jetting scours the grease off the pipe walls instead of punching a hole through it. For broader kitchen drain service, see our commercial drain cleaning.
