What Causes a Clogged Drain and How to Prevent It

Clogged drains happen when materials accumulate faster than your pipes can carry them away. For most households, the typical culprits are simple, everyday substances rather than mysterious blockages. Knowing what to watch for and how to intervene can save time, money, and stress.

Common causes

Hair is a frequent offender in bathroom drains. It can combine with soap and mineral deposits to form clogs in the trap and pipes. In the kitchen, FOG (fats, oils, and grease) from cooking can solidify as it cools, trapping food particles and causing slow drainage or full blockages. Soap scum, toothpaste, and mineral buildup from hard water can also contribute to gradual drain slowing, especially in showers, sinks, and bathroom tubs.
