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.
