Plumbing issues are frustrating enough without outdated advice making them worse. Over the years, countless plumbing myths have spread—often passed down by word of mouth or well-meaning DIYers. Believing these myths can lead to expensive damage, safety hazards, and major water waste. It’s time to clear the air and set the record straight.
Here are the most common plumbing myths and the truth behind them.
Myth #1: Lemons Clean Your Garbage Disposal
Many homeowners toss lemon peels into their garbage disposal, believing it cleans the blades. While lemons may leave a fresh scent, they do little to clean the disposal. Worse, citrus rinds can actually dull blades and contribute to clogs over time. A better cleaning method? Use a mix of ice cubes and vinegar to clear gunk and sharpen blades.
Myth #2: A Slow Leak Is No Big Deal
A slow drip from a faucet or pipe might seem harmless, but it can waste hundreds of gallons of water each year and spike your water bill. Over time, that minor leak could also cause water damage or mold growth in hidden areas. Any leak—big or small—should be addressed immediately to avoid long-term damage.
Myth #3: Flushable Wipes Are Safe for Your Toilet
Despite being labeled “flushable,” most wipes don’t break down like toilet paper. They can clog pipes, damage septic systems, and cause backups in both residential and municipal plumbing systems. Stick to toilet paper only, and toss wipes in the trash instead.
Myth #4: Plumbing Fixtures Don’t Need Maintenance
Many people think that once plumbing is installed, it’s good for life. The truth is that fixtures, pipes, and seals wear out over time. Regular maintenance helps prevent leaks, clogs, and corrosion. For instance, flushing your water heater yearly can remove sediment buildup and extend its lifespan.
Myth #5: You Can Use Any Chemical Drain Cleaner
Off-the-shelf chemical cleaners may seem like a quick fix for a clogged drain, but they often do more harm than good. These harsh chemicals can corrode pipes—especially older ones—and leave you with expensive repairs. A safer approach is using a plunger or calling a professional plumber to snake the line properly.
Myth #6: All Plumbers Are the Same
Hiring any plumber without checking licensing, reviews, or availability can lead to trouble. Unlicensed or undertrained plumbers might cut corners, misdiagnose problems, or leave jobs unfinished. Always choose a licensed, insured, and experienced plumbing company—especially for emergency situations.
Myth #7: Hot Grease Can Be Rinsed Down with Hot Water
Grease might slide down the drain when it’s hot, but it eventually cools and hardens inside your pipes. This sticky buildup can catch other debris and lead to full-blown clogs. Always dispose of grease in a sealed container and throw it in the trash once cooled.
Myth #8: A Plunger Can Fix Any Clog
Plungers are useful but not a cure-all. Some clogs—especially deep in the sewer line—require specialized tools like plumbing snakes or hydro-jetting. If you find yourself plunging repeatedly without success, it’s time to call in a pro.
Myth #9: Toilets Flush Better with a Brick in the Tank
An old-school water-saving trick, placing a brick in the toilet tank, can actually damage your plumbing. Bricks can break down over time, clog pipes, and reduce flushing power. Instead, consider installing a low-flow toilet designed to conserve water without compromising performance.
Myth #10: DIY Repairs Are Always Cheaper
While DIY fixes might seem cost-effective, they often lead to more expensive problems later. Incorrectly installed pipes, over-tightened fittings, or misused tools can result in water damage, leaks, or even code violations. A professional plumber ensures the job is done right—the first time.
