Residential FOG

Fats, oils, and grease (FOG) poured down the drain can end up costing you money for sewer cleaning. Fats and greases tend to accumulate in drain pipes and sewer laterals by adhering to the pipe itself and/or getting caught among small tree roots that may be in your lateral. Pour grease down the drain on a frequent basis and your sewer lateral is likely to become restricted or plugged.

Some people think that they can safely pour grease down the drain by washing it down with hot tap water. In practice, the hot water solubilizes the grease only for a short distance before it cools and begins to cling to drain pipes and sewer laterals. The best practice is to pour excess fats and oils into a metal can and throw it in the garbage after it hardens. If you do have grease in the sink, it is best to wash it down with cold tap water.
