Hair and grease buildup are two of the most common causes of clogged drains. Over time, they create stubborn blockages that lead to slow drainage, unpleasant odors, and even costly plumbing repairs. According to a Plumbing & Mechanical Magazine report, the average household spends between $100-$400 annually on drain cleaning services and products. Fortunately, with the right preventative maintenance strategies, you can keep your drains clear and functional for years.
In this guide, we’ll cover the best preventative drain maintenance techniques, natural solutions, and expert tips to stop clogs before they start.
Why Hair & Grease Cause Drain Clogs
- Hair: When hair accumulates in your pipes, it forms tangled clumps that trap soap scum and debris, leading to blockages. Research by Mr. Rooter Plumbing reveals that hair clogs account for approximately 45% of all bathroom drain blockages.
- Grease: Grease solidifies as it cools, coating your pipes and catching food particles, which results in stubborn clogs. The Water Environment Federation data shows that FOG (Fats, Oils, and Grease) is responsible for 47% of sewer overflows in residential areas.
Understanding these causes is the first step to preventing them. Now, let’s explore the best ways to keep your drains clog-free.
