Keep your water heater running efficiently and reliably with this simple maintenance routine.


  • you'll save in energy costs if you lower the thermostat to 120 degrees, plus you’ll reduce the risk of scalding.

  • Always maintain 2 feet of clearance around the appliance unless the manual specifically states otherwise.

  • Drain about a quarter of the tank a few times a year to remove sediment and debris. please call for guidance before trying this at home!

  • Examine the sacrificial anode rod every three years by loosening the hex head screw and removing it. Replace the rod if:

    • More than 6 inches of the core steel wire is exposed.

    • The rod is less than 1/2 inch thick.

    • The rod is coated with calcium.

    • You can buy a 13-inch zinc-aluminum anode rod for about $16.


  • insulate the hot and cold water pipes.

  • When leaving town, adjust the thermostat on gas heaters to “vacation” setting, which maintains the pilot light without heating the water.
