Clogged drains are one of the most common household plumbing issues and one of the most frustrating. Whether it’s a slow sink or a backed-up shower, knowing what causes these blockages can help you prevent them before they start.
Here are the five most common reasons for residential drain clogs and how to keep your pipes flowing freely.
1. Hair and Soap Scum
Hair, especially in bathroom sinks and showers, binds with soap residue and forms stubborn clogs. Use drain covers to trap hair and clean them regularly. An occasional flush with baking soda and vinegar can also help break down buildup.
2. Grease and Cooking Oil
Pouring grease down the kitchen sink is a fast track to blockages. Even if it’s liquid when hot, it solidifies as it cools, coating the inside of pipes. Always dispose of oil and grease in a separate container and throw it in the trash.
3. Food Waste
Even with a garbage disposal, not all food scraps are safe for your drains. Avoid dumping coffee grounds, eggshells, rice, or fibrous vegetables like celery into the disposal. These items can cause clogs and damage blades over time.
4. “Flushable” Wipes and Hygiene Products
Despite labeling, most flushable wipes don’t break down easily and can lead to severe toilet and sewer line clogs. Stick to toilet paper and dispose of wipes and hygiene products in the trash.
5. Foreign Objects
From children’s toys to soap bits, small objects can accidentally fall into drains. Be mindful of what goes down, and teach young kids not to use toilets or drains as disposal bins.
Most clogs can be avoided with good habits and simple preventive tools. Following these summer plumbing tips, like using drain strainers and being cautious about what goes down your pipes, can help you avoid costly repairs and keep your residential plumbing system in top shape.
