Why Draining Your Water Heater is Important

Over time, sediment builds up at the bottom of your water heater. This sediment, primarily consisting of minerals like calcium and magnesium, can corrode your tank and decrease its efficiency. Draining your water heater removes this sediment, improving the heater’s performance and extending its lifespan. In Tempe, AZ, where mineral content in water can be high, regular draining by a trusted service like Peterson Air Care and Home Services is vital.

Step-by-Step Guide to Draining Your Water Heater


Step 1: Turn Off the Water Heater

For electric water heaters, ensure you turn off the power at the breaker. For gas units, shut off the gas or move the dial to the ‘pilot’ or ‘vacation’ setting. Remember, safety is paramount during water heater installation and maintenance in Tempe, AZ.

Step 2: Shut Off the Water Supply

Locate the cold water valve above your water heater and shut it off. This will stop more water from entering the tank during the draining process.

Step 3: Cool Down the Water

Allow the water inside the tank to cool for a few hours. This is crucial to prevent injuries from scalding water during the draining process. In Tempe, AZ’s warm climate, this might take longer than in cooler regions.

Step 4: Connect a Garden Hose

Attach a garden hose to the drain valve located at the bottom of your water heater. Ensure the other end of the hose is positioned in an area where hot water can safely drain.

Step 5: Open the Drain Valve

Before opening the drain valve, open a hot water tap in your home to prevent a vacuum from forming in the lines. Then, open the drain valve and let the water flow out. If you’re in Tempe, AZ, and uncomfortable with this step, Peterson Air Care and Home Services can assist with your water heater installation and maintenance needs.

Step 6: Flush the Tank

Once the water has drained, flush the tank with cold water to remove any remaining sediment. This can be done by briefly turning on the cold water supply to the tank.

Step 7: Refill the Tank

Close the drain valve and remove the garden hose. Turn on the cold water supply to the tank and wait until the tank refills.

Step 8: Restore Power or Gas Supply

Once the tank is refilled, turn the power back on for electric heaters or relight the pilot light for gas heaters. Ensure the tank is fully refilled before restoring power to prevent damage to the heating elements.

Troubleshooting Post-Drainage Issues

After draining your water heater, you may encounter leaks. Check the drain valve and tighten it if necessary. If the issue persists, it’s best to contact Peterson Air Care and Home Services for expert water heater maintenance in Tempe, AZ.
