If you have recently noticed small white particles floating in your home's hot water, then the hot water heater is having a problem with calcium buildup. The calcium in the water will eventually ruin your water heater and cause scale to form on your plumbing fixtures.
To remove the calcium inside of the water heater, you need to drain and flush it using these steps:
Step 1: Turn Off the Power and Water
To drain your water heater and flush out the calcium salt buildup, you need to first turn off the power at the breaker box. Also, you need to turn off the water supply valve at the top of the water heater.
Step 2: Attach a Garden Hose for Draining
Attach a garden hose to the drain connection at the bottom of your water heater. Place the other end of the hose either in your bathtub or outside through a window to water a tree.
Step 3: Drain the Water Heater
Turn on a faucet in your bathroom to allow the water to flow out of the water heater through the drain hose. Without turning on a faucet, the plumbing will stay pressurized and no water will flow from the hose.
Drain the water heater until no more water comes out.
Step 4: Flush the Water Heater
Turn on the cold water inlet on the top of the water heater's tank. Let the water flow into the tank and out of the garden house. This will flush out any remaining sediment sitting on the bottom of the tank. When the water is running clear out of the end of the drain hose, then turn off the water inlet and turn off the faucet in your bathroom.
Step 5: Remove the Hose and Fill the Water Heater
Remove the drain hose and turn on the water to fill up the water heater with cold water. Once it is full and the water stops running, then you can safely turn back on the power to heat the water.
Prevention of Calcium Water Scale
Finally, if you find chunks of calcium salts inside of your water heater, then you should speak with a plumbing professional like StateWide Mechanical II Inc. to determine if a water softener is necessary to prevent damage to your water heater and pluming in the future. A water softener will remove the calcium from the water before it has a chance to enter your home's water heater and plumbing system.
