Properly maintaining your home’s plumbing system is essential for avoiding costly repairs and major inconveniences. However, many homeowners unintentionally make mistakes that can lead to significant plumbing issues. Whether it’s attempting DIY repairs without the right knowledge or neglecting routine maintenance, these errors can cause unnecessary damage to your home’s plumbing system.

In this blog, we’ll discuss some of the most common plumbing mistakes homeowners make and provide expert tips on avoiding plumbing mistakes to keep your pipes, drains, and fixtures running smoothly.

1. Using Chemical Drain Cleaners Regularly

One of the most common mistakes homeowners make is using chemical drain cleaners to clear clogs. While these products may provide a temporary solution, they can cause long-term damage to your pipes. The harsh chemicals in these cleaners can erode the interior of your pipes, leading to leaks, corrosion, and more significant blockages.

How to Avoid This Mistake:

  • Use natural methods to clear minor clogs, such as a mixture of baking soda and vinegar, followed by hot water.
  • For tougher clogs, use a plunger or drain snake to manually remove the blockage.
  • If you’re dealing with recurring clogs, it’s best to call a professional plumber to assess and fix the issue rather than rely on chemical cleaners.

2. Overloading the Garbage Disposal

Garbage disposals are convenient tools, but they’re not designed to handle everything. A common mistake is treating the garbage disposal like a trash compactor, attempting to grind up foods that can damage the unit or cause blockages. Foods like fibrous vegetables, starchy foods (such as pasta and potatoes), and coffee grounds should never be put down the disposal.

How to Avoid This Mistake:

  • Always scrape large food scraps into the trash or compost bin before rinsing dishes in the sink.
  • Avoid putting fibrous, starchy, or greasy foods down the garbage disposal.
  • Run cold water for at least 10 seconds after using the disposal to flush any remaining debris through the pipes.

3. Over-Tightening Plumbing Fixtures

When dealing with leaky faucets or loose pipes, it’s common for homeowners to over-tighten plumbing connections or fixtures in an attempt to stop a leak. However, over-tightening can actually cause more damage, leading to cracked pipes or damaged fittings, which can result in leaks or even flooding.

How to Avoid This Mistake:

  • Tighten plumbing fixtures just enough to stop the leak or secure the connection.
  • Use plumber’s tape (also known as Teflon tape) to ensure a watertight seal.
  • If you’re unsure of how much pressure to apply, it’s best to consult a professional plumber for advice.

4. Neglecting Routine Maintenance

Plumbing systems require regular maintenance to function correctly and efficiently. Many homeowners overlook simple tasks like checking for leaks, flushing the water heater, or inspecting pipes for signs of wear and tear. Over time, this neglect can lead to more serious issues, such as burst pipes, clogged drains, or water heater failure.

How to Avoid This Mistake:

  • Schedule regular inspections of your plumbing system, including checking for leaks under sinks, inspecting the water heater, and testing water pressure.
  • Flush your water heater annually to remove sediment buildup that can reduce its efficiency and lifespan.
  • Clean your drains regularly by using natural cleaners and ensuring food waste and debris don’t accumulate in pipes.

5. DIY Plumbing Repairs Without Proper Knowledge

Many homeowners attempt DIY plumbing repairs to save money, but without the proper knowledge and tools, this can result in even bigger problems. Whether it’s installing a new fixture incorrectly or misdiagnosing a plumbing issue, DIY mistakes can lead to water damage, costly repairs, or health hazards like mold growth.

How to Avoid This Mistake:

  • Only attempt plumbing repairs if you’re confident in your skills and knowledge.
  • For complex issues like pipe leaks, water heater problems, or sewer line blockages, always contact a licensed plumber.
  • If you’re not sure how to handle a plumbing task, consult online tutorials or guides, or better yet, leave it to the professionals.

6. Flushing the Wrong Items Down the Toilet

Another common plumbing mistake is using the toilet as a trash can. Flushing non-flushable items like baby wipes, paper towels, feminine hygiene products, or cotton swabs can lead to severe blockages in your sewer line. Even items labeled as “flushable,” such as wipes, can cause clogs and plumbing issues over time.

How to Avoid This Mistake:

  • Only flush human waste and toilet paper down the toilet.
  • Dispose of non-flushable items in the trash.
  • Consider placing a trash bin in your bathroom to make proper disposal more convenient.

7. Improperly Installing Fixtures

Whether it’s installing a new faucet, toilet, or dishwasher, improper installation can lead to leaks, water damage, and even voided warranties. Failing to follow manufacturer instructions or use the right tools can result in costly repairs down the line.

How to Avoid This Mistake:

  • Always read and follow the manufacturer’s installation instructions carefully.
  • If you’re not comfortable with the installation process, hire a professional plumber to ensure the fixture is installed correctly and securely.
  • Check for leaks or other issues after the installation to ensure everything is working as intended.

8. Ignoring Signs of Leaks

Even small leaks can cause major damage over time, leading to structural issues, mold growth, and higher water bills. Many homeowners ignore the signs of leaks, such as damp spots, dripping sounds, or water stains, thinking they’re minor issues. However, left unchecked, these small problems can become significant headaches.

How to Avoid This Mistake:

  • Regularly inspect areas prone to leaks, such as under sinks, around toilets, and near water heaters.
  • If you notice any signs of a leak, address the issue immediately by tightening connections or replacing faulty parts.
  • For leaks that persist or worsen, call a professional plumber to assess the situation.

9. Failing to Shut Off the Water During Repairs

Before attempting any plumbing repairs, it’s crucial to shut off the water supply to the affected area. Failing to do so can result in flooding, water damage, and a much bigger mess than you initially anticipated.

How to Avoid This Mistake:

  • Familiarize yourself with the location of your home’s main water shutoff valve and individual shutoff valves for sinks, toilets, and appliances.
  • Always turn off the water before starting any plumbing work, even for minor repairs.
  • Test the shutoff valve before beginning work to ensure that the water supply is fully turned off.

10. Ignoring Water Heater Maintenance

Water heaters play a vital role in your home’s plumbing system, but they’re often neglected. Failing to maintain your water heater can lead to decreased efficiency, higher energy bills, and potential breakdowns.

How to Avoid This Mistake:

  • Flush your water heater at least once a year to remove sediment buildup.
  • Inspect the temperature setting and adjust it to 120°F for optimal efficiency and safety.
  • Check the pressure relief valve to ensure it’s functioning properly.
  • If your water heater is more than 10-12 years old, consider replacing it before it fails.
