You might have heard strange stories about pipes and plumbing that seem to make sense but cause more harm than good. These plumbing myths can send you chasing solutions that harm your home or waste your cash. You want clear facts so you can care for your plumbing the right way. In this article, we tackle ten plumbing myths that you should stop believing.
Turning Up the Temperature Heats Water Faster
Many homeowners believe that cranking up the thermostat makes hot water arrive quicker. In reality, raising the temperature only makes the stored water hotter, not faster. Water flow speed depends on pipe length and pressure, not thermostat settings. Overheating your water heater can even create safety risks, like scalding taps or added strain on the tank. A plumber can adjust your system, insulate pipes, or install a recirculation pump to truly speed delivery. You avoid higher energy bills by keeping the thermostat at a safe level. Regular maintenance also ensures the heating elements or burner are working efficiently. Scheduling a yearly inspection helps keep your system safe, saves energy, and extends the life of your water heater.
A Slow Drip Does Not Matter
You may believe that a barely noticeable drip wastes little water. A single slow drip can leak thousands of gallons each year. That waste adds up on your bill and invites mold. A dripping faucet or joint can signal worn washers or corroded parts. You save water and money when you fix that drip early. A quick repair keeps your pipes healthy and your wallet happy. Ignoring a drip also risks wood rot under sinks or in vanities. You maintain home value by staying ahead of small leaks before they turn into major repairs.
Flushable Wipes Are Harmless
Some brands label wipes as flushable, and you may trust that claim. Wipes do not break down like toilet paper. They tangle in pipes and form stubborn clogs. Those clogs can force raw sewage into your home or yard. A plumber uses special tools to clear wipes from deep inside drains. You avoid that hassle by tossing wipes in the trash instead of the toilet. Drain blockages caused by wipes often go unnoticed until a complete backup happens. You protect your pipes and local water systems when you handle wipes correctly.
A Brick in The Tank Saves Water
You might think that dropping a brick in the toilet tank reduces flush volume. Bricks crumble over time and can damage the flapper valve. A damaged flapper causes running toilets and higher bills. You gain no real savings and risk leaks that run constantly. A modern low-flow toilet or adjustable fill valve gives real water savings without the risk. Upgrading to newer models can cut your water use by half and avoid constant tank tinkering. You invest once for lasting performance.
Ice Cubes Sharpen Disposal Blades
You may hear that tossing ice in the garbage disposal sharpens its blades. Disposal blades do not sharpen by hitting ice. Frequent ice use can dull cutters and crack the grinding ring. Ice can help clear light debris if used now and then, but it will not sharpen metal. You keep the disposal clean by running water while you grind small bits of vegetable peelings. Proper care involves trimming fiber-rich scraps and avoiding hard materials that stress the motor. You protect your unit and extend its service life with careful use.
Chemical Drain Cleaners Are Safe
You may pour a commercial drain cleaner down a slow sink or shower. Those chemicals eat through clogs but also corrode metal and harm plastic pipes. Harsh cleaners can burn your skin if they splash back when you plunge. A plumber uses tools or natural enzymes to break clogs safely. You protect your pipes and skin when you skip harsh chemicals. Enzyme-based products can often clear blockages without risk. You handle clogs with minimal cost and avoid hidden damage that may show up months later.
It Is Fine to Flush Cat Litter
You may think that flushing cat litter down the toilet does not matter if it goes away. Cat litter contains clay and chemicals that do not dissolve. That waste can harden and build clogs in sewer lines. Cat waste also carries harmful pathogens into water systems. A plumber may need to remove hardened blocks deep in the pipe. You avoid that by bagging litter and throwing it in the trash. Keeping litter out of plumbing preserves smooth flow and spares you from emergency cleanups that cost far more than a simple bag.
Pouring Grease Down the Sink Causes No Harm
You might believe that hot grease is fine if it flows down the drain. Grease cools and solidifies inside pipes. Over time, it narrows the passageway and causes backups. You face messy clogs that require snaking or hydro-jetting to clear. A plumber can remove hardened grease, but only after it costs you time and money. You keep pipes clear by wiping pans and pouring cooled grease into a sealed container. A scrap jar by the stove makes it easy to catch and toss fats. You maintain an easy-drain system and avoid surprise slowdowns.
Flushing A Goldfish Is Harmless
A story claims that flushing a goldfish down the toilet lets it swim away safely. If the fish is alive, it can clog traps or travel to local waterways and harm ecosystems. Even dead fish do not dissolve quickly and can clog curves in the drain. A plumber may need to retrieve the fish from a trap or a bend in the pipe. You avoid that risk by placing the fish in a sealed bag and disposing of it in the trash. You protect your pipes and local streams by choosing safe disposal.
A Dry Patch Means No Problem
You may think that if water does not pool on the floor, then no leak exists. Some leaks hide inside walls or under slabs without visible signs. You might smell mildew or hear faint drip sounds. A hidden leak can erode foundations and mold behind drywall. A plumber uses cameras or moisture meters to find these hidden leaks fast. You protect your home’s structure and air quality by calling for help on any unusual hint. Early detection avoids weeks of hidden damage and costly reconstruction later.
