All Suburban Hot Water systems have an anode rod which absorbs all the corrosive action of hot water. It is located on the bottom on the HWS under the main burner; you simply unscrew this to drain the tank of water. If the rod is mostly eaten away, simply replace it with a new one.

There are many anode rods available on the market so you need to take care of the length of an anode rod. The Suburban Anode Rod is made for use in the 4, 5 & 6 Gallon tanks. Please be aware that some imitation anode rods can cause damage to your Suburban HWS.
