How to Extend the Life of Your Water Heater with Routine Maintenance

Posted December 26, 2024

Regular maintenance is key to keeping your water heater running efficiently and prolonging its lifespan. Whether you have a conventional tank-style water heater or a modern tankless system, these maintenance tips will help you avoid costly repairs, improve energy efficiency, and maximize the performance of your unit.

Tank-Style Water Heater Maintenance

Conventional tank-style water heaters typically last 8-10 years, but without proper care, sediment and rust buildup can shorten their lifespan and waste energy. To ensure your tank water heater operates efficiently, follow these annual maintenance steps:

  1. Drain the water heater tank: Over time, sediment accumulates in the tank, particularly in homes with hard water. Attach a hose to the drain valve at the bottom of the tank, ensuring the opposite end is placed outside or near a floor drain. Open the valve carefully, as the water may be very hot. If unsure how to flush your water heater, call ABC Plumbing for expert assistance.
  2. Check for leaks and rust: Inspect the exterior of the tank for pinholes, rust spots, or water leaks, which may indicate the need for repair or replacement.
  3. Inspect the flue for gas water heaters: Ensure exhaust fumes are venting outside by striking a match next to the flue housing. The smoke should drift out through the exhaust flue. Contact a professional if it doesn’t.
  4. Test the temperature-pressure (T&P) relief valve: Place a bucket under the drain pipe, then open the valve. Water should flow freely; if it doesn’t, replace the valve.
  5. Set the thermostat: Maintain the water heater’s thermostat between 120°F and 125°F. For homes with young children, consider lowering the temperature to 115°F to prevent scalding.
  6. Use a drip pan: Placing a pan beneath the water heater helps detect leaks early and contains any minor water discharge.
  7. Check the pilot light: For gas models, ensure the pilot light burns blue and steady. A yellow or flickering flame may indicate a problem that requires attention.

Tankless Water Heater Maintenance

Tankless water heaters are an energy-efficient alternative to traditional models, offering on-demand hot water while reducing energy consumption. However, they require regular maintenance to maintain efficiency and meet warranty conditions. Here’s how to care for your tankless system:

1. Inspect and Clean the Screen Filter

The screen filter, located on the water inlet side of the tankless unit, prevents debris from entering the system. Following the manufacturer’s recommendations:

  • Turn off the power and water supply to the unit.
  • Carefully remove and clean the screen filter using vinegar, avoiding harsh chemicals that can contaminate your water.
  • Reinstall the filter securely and test the system to ensure proper function.

If you’re not comfortable performing this maintenance, contact ABC Plumbing for professional assistance.

2. Flush the System

To prevent lime and scale buildup, flush your tankless water heater periodically. Lime and scale can reduce efficiency and cause damage over time. Follow these steps:

  • Turn off the power and water supply to the unit.
  • Use a pump to circulate white vinegar through the system, avoiding chemical cleaners that can compromise water safety.
  • Flush thoroughly and rinse with clean water before restoring power and water supply.

Performing these steps regularly ensures your tankless water heater operates efficiently and lasts for many years.
