Top 5 Causes of Clogged Drains and How to Prevent Them


Clogged drains can be a constant headache, causing slow drainage, unpleasant odors, and sometimes costly repairs. Understanding the common causes of clogged drains and knowing how to prevent them can help keep your plumbing system running smoothly. Here are the top five culprits behind drain clogs and simple prevention tips to keep your pipes clear. At Isley & Sons Plumbing, we specialize in diagnosing and treating all types of drain clogs, so you can rely on us to keep your drains in top shape.

1. Hair Buildup

One of the most common drain clogs in bathrooms is caused by hair buildup. Hair can easily slip down the drain during showers, and over time, it forms tangles that trap soap, dirt, and other debris. This combination creates a sticky mess that clogs drains, slowing the water flow or blocking it completely.

Prevention Tip: Use a drain cover to catch hair before it goes down the drain, and clean it regularly to keep water flowing smoothly. Regular maintenance, like monthly flushing with hot water, can also help dissolve any mild blockages caused by hair.

2. Grease and Food Particles

In the kitchen, grease and food particles are major contributors to common drain clogs. Grease may seem harmless in liquid form, but once it cools, it solidifies and sticks to the insides of your pipes. This sticky residue traps food particles and other debris, leading to a stubborn clog.

Prevention Tip: Avoid pouring grease down the sink and dispose of it in a separate container instead. Scrape food scraps into the trash or compost before rinsing dishes in the sink. To keep your kitchen pipes clean, occasionally flush the drain with hot water and a bit of dish soap to break down any grease buildup. If you’re facing frequent issues, consider reaching out to Isley & Sons Plumbing for a thorough drain cleaning.

3. Soap Scum and Mineral Buildup

Soap scum and mineral deposits can lead to serious blockages over time. Hard water minerals like calcium and magnesium react with soap to create a filmy residue that sticks to pipes. This buildup reduces water flow, leading to potential clogs in bathrooms and laundry rooms.

Prevention Tip: Installing a water softener can minimize mineral buildup, making your water gentler on pipes. Using liquid soap instead of bar soap can also reduce soap scum accumulation. Additionally, cleaning your drains regularly with a solution of hot water and vinegar can help dissolve mineral deposits and prevent clogged drains.

4. Small Objects and Foreign Materials

A common cause of drain blockages is flushing small, non-biodegradable items down the toilet or sink. Items like cotton swabs, wipes, paper towels, and even dental floss do not break down and can quickly accumulate in pipes, creating a serious clog.

Prevention Tip: Only flush toilet paper and human waste down the toilet, and keep a waste bin nearby for other items. Educating household members on what can and cannot go down the drain can also help prevent clogged drains. If you do encounter a clog from foreign materials, professional intervention from Isley & Sons Plumbing can resolve the issue without risking pipe damage.

5. Tree Roots

Tree roots are an outdoor cause of clogged drains that many homeowners overlook. Roots naturally seek out moisture, so even the tiniest crack in an underground pipe can attract them. As roots grow, they can infiltrate the pipes, leading to blockages or even pipe damage.

Prevention Tip: Schedule regular inspections if you have large trees near your plumbing system. A plumber can use a camera to check for root intrusion and recommend solutions like root barriers or hydro jetting to keep roots from taking over your pipes. Addressing tree root issues early can save you from costly sewer line repairs down the road.

Clogged drains are a hassle, but with proper prevention, you can avoid many common causes of clogged drains. By following these simple tips, you’ll keep your plumbing system running smoothly and reduce the risk of major blockages. For persistent issues, consider professional drain clog prevention services.
