Keep Fats, Oils and Grease out of the Sewer
When it’s washed down the sink, grease from meat fats, lard, oil, shortening, butter, margarine, food scraps, baked goods, sauces and dairy products sticks to the insides of sewer pipes.
Over time it can build up and block an entire pipe on your property or in the street. Moreover home garbage disposals do not keep grease out of the plumbing system. Hot water and products, such as detergents that claim to dissolve grease, only pass it down the line; the grease hardens when it gets cold and causes problems elsewhere.
