Home >> 10 Plumbing Myths Debunked

March 4, 2025

Plumbing is one of those aspects of homeownership that often gets overlooked until something goes wrong. Unfortunately, many misconceptions about plumbing can lead to costly mistakes, unnecessary repairs, or even damage to your home. To help you identify fact from fiction, in this post we debunk 10 common plumbing myths that could save you time, money, and headaches.

Myth 1: Lemons clean your garbage disposal

While lemons can mask odors temporarily, they don’t actually clean your garbage disposal. The citric acid in lemons can corrode the metal components of the disposal over time, leading to premature wear and tear. Additionally, the fibrous nature of lemon peels can contribute to clogs in your pipes.

What you should do instead: For a safer and more effective cleaning method, use a mixture of baking soda and vinegar. Pour half a cup of vinegar and half a cup of baking soda down the disposal. Let it sit for 10-15 minutes, then flush it with cold water. This combination helps break down grease and grime without damaging your disposal.

Myth 2: A leaky faucet is no big deal

A dripping faucet may seem like a small inconvenience, but over time, it can waste a lot of water. The U.S. Environmental Protection Agency (EPA) estimates that a single leaky faucet dripping at one drop per second can waste more than 3,000 gallons of water annually. Over time, this wasted water can significantly increase your utility bills.

What you should do instead: Fixing a leaky faucet is often a simple repair that can save you money and conserve water. If you’re unsure how to fix it, call a professional plumber to address the issue promptly.

Myth 3: Flushable wipes down the toilet are safe

Despite the name, flushable wipes are not truly safe for your plumbing system. Unlike toilet paper, these wipes do not break down easily and can cause blockages in your pipes. In fact, they are a leading cause of sewer backups and costly repairs.

What you should do instead: Only flush toilet paper down the toilet. Dispose of wipes, even those labeled as flushable, in the trash to avoid plumbing disasters.

Myth 4: Running water while using the garbage disposal helps waste go down

While it’s true that running water while using the garbage disposal is necessary, it doesn’t mean you can dispose of anything. Grease, coffee grounds, and fibrous foods like celery can still clog your pipes, even with water running.

What you should do instead: Use cold water when running the garbage disposal, as it helps solidify grease and makes it easier to chop up. Avoid putting grease, coffee grounds, and fibrous foods down the disposal altogether.

Myth 5: Plumbing systems don’t need maintenance

Many homeowners assume that plumbing systems only need attention when something breaks. However, regular maintenance can prevent major issues down the line. For example, inspecting your water heater, checking for leaks, and cleaning your drains can extend the life of your plumbing system and save you from unexpected repairs.

What you should do instead: Schedule annual plumbing inspections to catch potential issues early. A professional plumber can identify and address small problems before they become costly repairs.

Myth 6: Chemical drain cleaners are safe and efficient

Chemical drain cleaners might seem like a quick fix for clogs, but they can do more harm than good. These harsh chemicals can corrode your pipes over time, leading to leaks and costly repairs. They’re also harmful to the environment and can pose health risks if not used properly. 

What you should do instead: For minor clogs, use a plunger or a drain snake. For stubborn clogs, call a professional plumber to safely and effectively clear the blockage.

Myth 7: You can’t prevent frozen pipes

While frozen pipes are common in colder climates, they’re not inevitable. Insulating your pipes, keeping your home heated, and letting faucets drip during freezing temperatures can prevent pipes from freezing and bursting.

What you should do instead: Insulate exposed pipes, especially in unheated areas like basements and attics. During extreme cold, let faucets drip to keep water moving through the pipes.

Myth 8: All plumbers are the same

Not all plumbers have the same level of expertise, licensing, or customer service. Hiring an unlicensed or inexperienced plumber can lead to subpar work and even more problems down the line.

What you should do instead: Always choose a licensed and insured plumbing company with a proven track record, like Haltex Plumbing, to ensure quality service.

Myth 9: Water pressure should be as high as possible

High water pressure might feel great in the shower, but it can strain your plumbing system and lead to leaks or burst pipes.

What you should do instead: If your water pressure is too high, consider installing a pressure regulator to protect your pipes and appliances.

Myth 10: DIY plumbing repairs always save money

While DIY projects can be rewarding, plumbing repairs are best left to professionals. A small mistake, like using the wrong type of pipe or improperly sealing a joint, can lead to major issues like leaks, water damage, or even mold growth. 

What you should do instead: Hiring a professional plumber ensures the job is done right the first time, saving you money in the long run.
