Restaurants wastewater enters grease traps from 3-compartment sinks and automatic dishwashers. The grease trap tank acts as a reservoir holding the wastewater and food solids that enter the trap as the wastewater cools, the fat oil, and grease (FOG) harden and the food solids settle. The FOG, being lighter than water, floats to the top of the grease trap. The FOG and food solids remain in the tank, increasing in volume daily. Food solids and grease sludge (brown grease) settle to the bottom of the grease trap.
So if you take a bucket of water and pour FOG, the FOG will float to the top of the bucket and harden. A grease trap functions in the same manner. FOG fills a grease trap from the top of the tank to the bottom. So the FOG fills the grease trap from top-down, displacing the wastewater from the middle of the grease trap and into the sanitary sewer or septic system. In-ground grease interceptors work in the same method but at a larger scale.
Grease trap pumping is having a large liquid holding truck come to your foodservice facility. So the truck, equipped with a large tank, brings the hoses inside the facility to the grease trap. The complete contents of the grease trap are pumped back into the truck’s tank.
Be sure to always get a quote first for grease trap pumping. Like every business, there are always unscrupulous operators. A common scam of grease trap pumping companies is “skimming”. Instead of the pumping company taking the complete contents of the grease trap the pumping company only takes off the very top layer of grease from the interceptor tank. This practice will lead to the grease trap backing up and overflowing.
So most of all this may save you money and nasty inconveniences. So choose a reputable and licensed grease trap pumping company. Like us! Express Plumbing Heating & Air!
