Water Heater Maintenance Tips for Homeowners: Extend the Life of Your Unit

Posted June 18, 2015

A well-maintained water heater not only provides reliable hot water but also saves energy and extends the unit's lifespan. In this guide, we’ll discuss the importance of water heater maintenance and provide practical tips to keep your unit running efficiently.

Why Is Water Heater Maintenance Important?

Over time, sediment and mineral buildup can accumulate at the bottom of your water heater tank. This buildup reduces efficiency, increases energy costs, and can shorten the lifespan of your unit. Regular maintenance, such as flushing the tank and inspecting key components, ensures your water heater operates at peak performance.

Annual Water Heater Maintenance Checklist

Follow these steps to keep your conventional tank-style water heater in excellent condition:

  • Flush the Tank: Drain the water heater tank annually to remove sediment. Sediment buildup can insulate the water from the heating elements, forcing the unit to work harder.
  • Inspect the Anode Rod: The anode rod protects the tank from corrosion. Check it annually and replace it if more than 50% is corroded.
  • Check the Temperature-Pressure Relief (TPR) Valve: Test this safety feature to ensure it’s functioning properly. Place a bucket under the discharge pipe and open the valve; water should flow freely.
  • Adjust the Thermostat: Set the water heater temperature to 120°F for optimal energy savings and to prevent scalding.
  • Inspect for Leaks: Check the base of the unit and connections for water leaks. Address any issues promptly to avoid damage and inefficiency.

Signs Your Water Heater Needs Maintenance

Watch for these warning signs that your water heater may require immediate attention:

  • Strange Noises: Popping or rumbling sounds often indicate excessive sediment buildup.
  • Inconsistent Water Temperature: Fluctuating temperatures may point to a failing heating element or thermostat.
  • Rusty or Cloudy Water: This could be a sign of corrosion inside the tank.
  • Reduced Hot Water Supply: If your tank is no longer meeting your household’s needs, it may be time for maintenance or an upgrade.

Proactive Maintenance for Tankless Water Heaters

If you have a tankless water heater, maintenance is equally important. Regularly descale the unit to prevent mineral buildup and clean the in-line screen filter to ensure proper water flow. Refer to the manufacturer’s recommendations for a specific maintenance schedule.

Benefits of Professional Water Heater Maintenance

While some maintenance tasks can be handled by homeowners, others are best left to professionals. Professional services include:

  • Comprehensive inspection of all components, including burners and electrical connections.
  • Thorough cleaning and descaling to remove sediment and minerals.
  • Testing of safety features, such as the TPR valve and gas connections.
  • Recommendations for repairs or replacements if needed.

Scheduling an annual tune-up with a licensed plumber ensures your water heater remains efficient, safe, and reliable.

FAQs About Water Heater Maintenance

  • How often should I flush my water heater?
    It’s recommended to flush your water heater at least once a year to remove sediment buildup.
  • What is the average lifespan of a water heater?
    Conventional tank water heaters last 8-12 years, while tankless models can last 20 years or more with proper maintenance.
  • Can I perform maintenance tasks myself?
    Basic tasks like flushing the tank and checking the thermostat can be DIY-friendly, but annual professional inspections are advisable.
