Clogged DrainsClogged drains are a major pain! One thing you can do to help prevent your drains from clogging is to keep out FOG. Fats, oils and grease can be a big problem when they make their way into your pipes. Although oils and grease may seem okay to pour down the drain in their liquid from, they instead separate from water and solidify, sticking to pipe walls and creating a buildup that can clog the sink. Your best bet is to dispose of all fats, oils and grease in a closed container in the garbage and give your drain a break.
