Essential Tips for Water Heater Maintenance in San Antonio

At Murray Plumbing, we understand the importance of maintaining your water heater to ensure a steady supply of hot water in your San Antonio home. Regular water heater maintenance can help extend the life of your unit, improve efficiency, and prevent costly repairs. Here are some essential tips for water heater maintenance:

  1. Schedule Annual Professional Inspections
    • Having a professional plumber from Murray Plumbing inspect your water heater annually is crucial. Our experts will thoroughly examine your unit, identify potential issues, and make necessary repairs to keep your water heater running efficiently.
  2. Flush the Tank Regularly
    • Over time, sediment can accumulate at the bottom of your water heater tank, reducing efficiency and potentially causing damage. Flushing the tank annually helps remove this sediment. To do this, turn off the power or gas supply, attach a hose to the drain valve, and let the water drain until it runs clear.
  3. Insulate the Tank and Pipes
    • Adding insulation to your water heater tank and pipes can help maintain water temperature, reduce energy costs, and extend the life of your unit. Proper insulation also minimizes the risk of pipes freezing during cold San Antonio winters.
  4. Adjust the Temperature Setting
    • Many water heaters are set to temperatures as high as 140°F, which can be unnecessarily hot and energy-consuming. Lowering the temperature to around 120°F can save energy, reduce the risk of scalding, and prolong the life of your water heater.
  5. Test the Temperature Pressure Relief Valve
    • The temperature pressure relief (TPR) valve is a critical safety feature that prevents excessive pressure buildup in your water heater. Test the TPR valve monthly by lifting the lever and allowing some water to flow out. If the valve fails to release water or continues to leak after testing, contact Murray Plumbing for a replacement.
  6. Check and Replace the Anode Rod
    • The anode rod attracts corrosive elements in the water, protecting your water heater tank from rust and corrosion. Inspect the anode rod every few years and replace it when it’s more than half consumed. This simple step can significantly extend the life of your water heater.
  7. Replace the Air Intake Filter (for tankless water heaters)
    • If you have a tankless water heater, regularly replacing the air intake filter is essential. A clean filter prevents dust and debris from entering the unit, ensuring optimal performance and preventing overheating.
