Grease trap cleaning needs to occur at regular intervals by a licensed trade waste collection contractor. A grease trap collects fats, oil and grease by allowing them to float to the surface and waste food solids to settle on the bottom of the tank. Over time these waste products accumulate.
The frequency between pump outs may range from several weeks to several months. The licensed trade waste collection contractor will use a suction pump to remove all of the contents and wash and scrape the walls and baffles of the grease trap. Installing a larger grease trap may reduce the frequency and ongoing cost of pump outs.
