Clogged drains are among the most common plumbing issues that are experienced by homeowners. If you find yourself contacting plumbers to perform drain cleaning on a regular basis, you may want to take some steps to help prevent clogs in the future. Learning about the common causes of clogged drains is among the most effective methods of clog prevention. In your kitchen, cooking grease and food scraps are common drain clogging culprits. When cooking grease is poured down the drain, it can cool down and create a serious blockage. Rather than pouring cooking grease down the drain, it is important to properly dispose of it in the garbage.
