What not to put in drain—it’s a question every Southern California homeowner should ask before turning on the tap. Every year, thousands of families in Los Angeles, Orange County, Long Beach, and surrounding areas deal with kitchen sink clogs and expensive plumbing repairs. But these problems are often preventable! In this guide, A-1 Performance Rooter and Plumbing reveals the top five items you should never flush or rinse down your drain—and smart alternatives to keep plumbing disasters at bay.

1. Grease and Oils: Leading Cause of Kitchen Sink Clogs

Fats, oils, and grease are notorious for causing stubborn blockages. When hot, they may seem harmless, but as they cool inside your pipes, they solidify and trap debris. Greasy buildup is a top reason for kitchen sink clogs in Los Angeles apartments and homes all across Orange County.

Instead: Pour cooled grease into a can or jar, seal it, and discard it with your household trash. Wipe pans with a paper towel before washing.

2. Coffee Grounds: Silent Drain Cloggers

Coffee grounds may seem small, but they accumulate fast—especially in busy homes and offices. Unlike water-soluble waste, grounds bind together, creating gritty clumps that block pipes.

Instead: Compost your grounds or toss them in the trash. They’re a great addition to garden soil and far safer than risking a blockage!

3. “Flushable” Wipes and Paper Towels: Drain Maintenance Tips

Manufacturers may claim “flushable” wipes break down, but they don’t disintegrate like toilet paper. Even in state-of-the-art plumbing systems, wipes and paper towels tangle together, snaring other debris and causing tough clogs.

Instead: Dispose of wipes, paper towels, and feminine hygiene products in a lined wastebasket. Only flush human waste and toilet paper.

4. Hair: The Sneaky Bathroom Clog Culprit

Hair may seem too thin to matter, but it easily snags inside shower and sink drains. Over time, hair tangles with soap scum to form sticky, resilient clogs.

Instead: Use hair catchers or drain screens in showers and bathroom sinks. Regularly clear out visible hair, and run hot water to help move small particles through the system.

5. Harsh Chemicals: Hidden Plumbing Hazards

While it’s tempting to pour chemical drain cleaners down slow drains, they can corrode pipes, harm the environment, and worsen existing issues.

Instead: Practice preventative maintenance. Use natural solutions (like baking soda and vinegar) for minor buildup, and schedule annual professional drain cleaning for persistent issues.

How to Prevent Clogged Drains: Expert Tips for Southern California

According to plumbing industry studies, up to 47% of household drain clogs could be prevented just by following these basic tips. Local climate also plays a role: Southern California’s frequent droughts and water conservation efforts can reduce water flow, making it even easier for debris to accumulate and cause blockages.
