How to Extend the Life of Your Water Heater

April 26, 2025

Your water heater is one of the most important appliances in your home, providing hot water for bathing, cooking, and cleaning. With proper maintenance, you can extend its lifespan and ensure it operates efficiently for years to come. At Patrick David Plumbing, we’ve helped countless homeowners in Pittsburgh maintain their water heaters, and we’re here to share some key tips to keep yours running smoothly.

1. Flush Your Water Heater Regularly

Over time, sediment and minerals from your water supply can build up inside the tank, reducing efficiency and causing damage. To prevent this:



  • Turn off the power to your water heater (electricity for electric models, gas for gas models).
  • Attach a hose to the drain valve and direct the water to a safe drainage area.
  • Open the valve and let the water flow out until it runs clear.
  • Close the valve and refill the tank before restoring power. Flushing your tank once or twice a year can help prevent clogs and improve performance.

2. Check and Replace the Anode Rod

The anode rod is a crucial component that prevents rust and corrosion inside your water heater. This rod attracts corrosive elements, sacrificing itself to protect the tank. To maintain it:



  • Turn off the water heater and let it cool.
  • Locate the anode rod (usually accessible from the top of the unit).
  • Unscrew and inspect the rod—if it’s corroded or less than half an inch thick, it’s time to replace it. Replacing the anode rod every 3-5 years can significantly extend your water heater’s lifespan.

3. Adjust the Temperature Settings

Many water heaters are set too high, which not only increases energy costs but also accelerates wear and tear. For optimal performance:



  • Set the temperature to 120°F—this prevents overheating and reduces the risk of scalding.
  • Use a thermometer to check the actual water temperature at the tap.
  • Adjust the thermostat accordingly. This simple adjustment can help you save energy and reduce stress on the unit.

4. Insulate Your Water Heater and Pipes

If your water heater is in a cold area, such as a basement or garage, insulation can help it work more efficiently:


  • Wrap the tank in a water heater insulation blanket.
  • Insulate exposed hot water pipes to reduce heat loss. This can lower your energy bills and reduce strain on the heater.

5. Schedule Professional Maintenance

While DIY maintenance is important, professional inspections can catch problems early and extend the lifespan of your unit. At Patrick David Plumbing, we offer comprehensive water heater services, including inspections, repairs, and replacements to keep your system in top condition.
