Mag-Erad is a descaler that dissolves sediment. A.O. Smith, who also makes water heaters. Follow the instructions, but don’t forget to turn the gas water heater on. Set the flame to PILOT and turn it off. Heat without water can damage gas heaters. Lye can also be used to dissolve sediment. It is highly flammable, volatile and can cause fires. This chemical should only be used by plumbers.
Maintenance Tip #3: Controlling sediment
Softened water can help keep sediment under control. Salt-softened water doesn’t reduce sediment, it just makes it worse. The life expectancy of anode rods is decreased by 50% to 65%. At 140 degrees, sediment can grow quickly. Legionnaires’ Disease can be grown at temperatures below 115°F. It is best to keep these two problems at bay by setting your water heater at 130°. Legionnaires Disease can be caused by inhaling infected water vapor, rather than from drinking it. To kill any remaining bacteria, the plumbing in hospitals should be refilled with 170-degree water.
You can only check the temperature of the water by filling a cup with hot water and placing a meat thermometer inside. The dial of a gas water heater can be adjusted to get hot water at 130 degrees. Between adjustments to the dial, give the water heater time to recover. It should take at least an hour. Gas water heaters may adjust the size of flames.

Install a water heater pressure reduction if you have high water pressure above 50 psi. Sediment buildup is more common when water pressure is high.
