The Ultimate Guide to Water Heater Maintenance

Keeping your water heater in good shape is important to make sure you always have hot water in your home, avoid taking cold showers, and make the unit last longer. Here is the best guide to taking care of your water heater, with clear steps and expert advice!

How to Maintain a Tank Water Heater – Step-by-Step

If you have a tank water heater, these simple steps can keep it in great shape:

Step 1: Turn Off the Water Heater

  • Gas Water Heater: Set the thermostat to “Pilot” mode.
  • Electric Water Heater: Turn off the power at the breaker box to ensure safety during maintenance.

Step 2: Shut Off the Cold Water Supply 

Locate the cold water valve at the top of the water heater and turn it off. This prevents additional water from entering the tank during the flushing process.

Step 3: Connect a Hose and Drain the Water 

Attach a garden hose to the drain valve at the bottom of the tank, making sure the other end is in a safe drainage location, like a floor drain or outside. Open the drain valve to let the water flow out, being careful as it might be hot.

Step 4: Open the Pressure Relief Valve 

To allow air into the tank, open the pressure relief valve on the top of the water heater. This will help the water flow out more easily.

Step 5: Flush the Tank 

Once the water has drained, turn the cold water back on for a few minutes to stir up any remaining sediment. Let the water run until it flows clear, ensuring all debris is removed.

Step 6: Close the Valves and Refill 

Close the drain valve and pressure relief valve, then turn the cold water supply back on. Open a hot water tap somewhere in your home to release any trapped air from the system until a steady stream of water flows out.

Step 7: Turn the Water Heater Back On

  • Gas Water Heater: Set the thermostat to your desired temperature.
  • Electric Water Heater: Switch the power back on at the breaker box.

Step 8: Check for Leaks Inspect around the drain valve, pressure relief valve, and other connections to ensure there are no leaks. If everything looks good, you are done!
