Common Plumbing Myths Debunked by a Professional Lakeway Plumber

As important as plumbing is in a household, most homeowners don’t think much about it—until a pipe bursts, a drain backs up, or worse, water starts seeping into walls and floors.

By then, the damage is often already done: warped floors, mold growth, and structural damage that can cost thousands to repair. Some moisture-related issues are so severe they can’t even be fully reversed, leaving behind lingering problems like weakened foundations or persistent mildew.  

Many of these disasters stem from preventable mistakes—myths and misconceptions that lead to improper maintenance, DIY mishaps, or just plain bad habits. To help you avoid costly water damage and emergency repairs, this article debunks the biggest plumbing myths with expert insights. Knowing the truth now could save your home—and your wallet—from real trouble down the line.

Myth #1: Flushable Wipes Are Safe for Your Toilet

One of the most common myths is that ‘flushable’ wipes can be safely disposed of down the toilet. Neighborhood Plumbing & Drain, a plumbing company in Lakeway, TX, warns that despite their labeling, these wipes don’t break down like toilet paper. According to these experts with over a decade of experience, the fibrous nature of toilet paper leads to stubborn clogs in sewer lines, contributing to serious issues and even damage in both residential and commercial plumbing systems.  

Baby wipes, sanitary items, and even cat litter can create massive blockages, requiring professional drain cleaning or even sewer cleanup efforts. Stick to toilet paper to avoid real trouble.  

Myth #2: Garbage Disposals Can Handle Anything

Many people treat garbage disposals like trash compactors, tossing in coffee grounds, eggshells, and hot grease. However, garbage disposal blades aren’t designed to grind everything. Grease clogs pipes as it solidifies, while coffee grounds accumulate in drain pipes, leading to nasty clogs.  

A better alternative? Use a handful of ice cubes and citrus peels to clean the disposal walls and keep them smelling fresh. Moreover, properly dispose of fibrous foods and non-disposable items in the trash to extend your disposal’s service life.  

Myth #3: Chemical Drain Cleaners Are the Best Solution  

Liquid drain cleaners and commercial drain openers promise quick fixes, but their harsh chemicals damage plumbing systems over time. The acid in lemon peels or a baking soda and vinegar mix can serve as a safer cleaning solution for minor clogs.  

For persistent blockages, expert plumbers recommend drain snakes or hydrojetting instead of risking pipe corrosion with chemical drain cleaners.  

Myth #4: Running Cold Water While Using the Disposal Prevents Clogs  

While cold water helps move food particles through pipes, it doesn’t make the disposal invincible. Avoid overloading it with excess food scraps, and always run water for a few seconds after shutting off the disposal to flush out debris.  

Myth #5: Bleach Tablets Keep Your Toilet Clean  

Bleach tablets in the toilet tank may provide a fresh scent, but they degrade the tank’s components, leading to leaks. Instead, use tank toilet cleaners designed for plumbing fixtures or opt for natural alternatives like citric acid.  

Myth #6: All Leaks Are Easy to Spot  

Not all leaks are apparent. Hidden leaks behind walls or under sinks can cause water damage and structural issues before you notice them. To prevent costly repairs, allot time for regular plumbing inspections and advanced leak detection.  

Myth #7: DIY Plumbing Repairs Always Save Money

While fixing a dripping faucet or replacing an air filter may seem simple, improper installation or incomplete repairs often worsen plumbing issues. Trusting an experienced plumber ensures high-quality assistance and prevents bigger problems.  

Myth #8: Hot Water Melts Grease in Pipes  

Don’t pour used oil or hot grease down the kitchen drain. It solidifies in cold pipes, creating a grease clog. Instead, collect the grease in a container and throw it in the trash.  

Myth #9: You Don’t Need to Maintain Your Water Heater

Many homeowners ignore their water heaters until they stop producing hot water, then face an expensive replacement. The truth is that regular maintenance can double their lifespan.

Here’s what you should do instead:

• Flush the tank annually to remove sediment buildup, which reduces efficiency.
• Check the anode rod every few years—it prevents corrosion inside the tank.
• Insulate older units to improve energy efficiency, especially in cold climates.

Ignoring water heater issues can lead to leaks, higher utility bills, or even a burst tank. For expert plumbing solutions, consider scheduling routine maintenance with a professional plumber.

Bonus Tip: Alternative Energy Options

If you’re upgrading, consider a tankless or heat-pump water heater for long-term savings. These systems provide instant hot water while using less energy, making them great for both residential and commercial plumbing needs.

Conclusion

Understanding these common plumbing myths can save you from costly mistakes. Rely on professional assistance for expert plumbing repairs, preventative maintenance, or emergency repairs. Whether it’s residential plumbing or commercial installations, proper care keeps your systems running smoothly.
