Maintenance Tip #1 Preparing the water heater
Turn off the power if it’s an electric water heater. Turn off the water to the water heater by closing the valve on the cold water line. Its located on top of the water heater. The cold line is always to the right. Open a hot water tap inside the house. Air pressure will come out of the tap.

Open the drain valve located at the bottom of the water heater. It looks like a hose bibb. Let a gallon or more out of the water heater. Do not allow anyone to use hot water for the time you are working on the water heater.
Maintenance Tip # 2 Removing sediment by dissolving it
Use the instructions that come with this descaler, but ignore the part about leaving the gas water heater on. The heat without water in the water heater can cause damage to the gas systems. You can also use lye to dissolve sediment. It’s very flammable and volatile.
Maintenance Tip #3 Controlling sediment
Sediment can be kept under control if you use softened water. Salt softened water only reduces sediment; it doesn’t get rid of the problem and also causes another problem. Anode rods’ life expectancy is reduced by 50% to 65%. Sediment grows rapidly at 140 degrees.
To keep both of these problems at bay, it’s best to set your water heater at 130 degrees. Legionnaires’ Disease is actually caused by inhaling water vapor rather than drinking infected water.
