Hot Tips for Water Heater Maintenance


A well-maintained water heater is not only essential for your daily comfort but also for the overall efficiency of your home’s plumbing system. Regular water heater maintenance can prevent costly breakdowns, extend the appliance’s lifespan, and ensure consistent hot water supply. In this blog post, we’ll delve into some hot tips for water heater maintenance that every homeowner should know.

Flush Out Sediment Buildup

Over time, sediment and minerals can accumulate at the bottom of your water heater tank, affecting its efficiency and reducing its heating capacity. To combat this, it’s recommended to flush out the tank annually. Here’s how:

  • Turn off the power supply to the water heater.
  • Attach a hose to the drain valve and place the other end in a suitable drainage area.
  • Open the drain valve to let the water and sediment drain out.
  • Close the drain valve and refill the tank before turning the power back on.

Check the Pressure Relief Valve

The pressure relief valve is a crucial safety component of your water heater. It prevents excessive pressure from building up inside the tank, reducing the risk of explosions. To test and maintain it:

  • Turn off the power to the heater.
  • Lift the lever on the relief valve to allow some water to discharge.
  • If water doesn’t flow or the valve doesn’t reset, it might be faulty and needs replacement.


Inspect Anode Rod

An anode rod is a sacrificial element that attracts corrosion to protect the tank’s interior. Regularly inspect the rod and replace it if it’s heavily corroded, as a worn-out rod can lead to tank corrosion.

  • To inspect, locate the anode rod’s access port at the top of the water heater.
  • If it’s more than 50% corroded, it’s time for a replacement.

Check for Leaks

Regularly inspect your water heater and the surrounding area for any signs of leaks. Leaks can lead to water damage and reduced efficiency. Address any leaks promptly by tightening connections or replacing faulty components.

Maintain Thermostat Settings

Keep the thermostat settings at a reasonable temperature (typically around 120°F or 49°C). This not only prevents scalding but also helps conserve energy. Extreme temperatures can cause the heater to work harder, leading to faster wear and tear.

Schedule Professional Inspections

While DIY maintenance is essential, it’s equally important to schedule professional inspections at least once a year. A licensed plumber can perform a thorough assessment, identify potential issues, and offer expert solutions.
