What does an anode rod do?
An anode rod protects a water heater from corrosive elements and damage: It attracts minerals and compounds, which corrode the rod instead of the tank interior.
Do gas water heaters have anode rods?
Yes, most gas water heaters have anode rods. If the tank is made of stainless steel or if your water heater unit is tankless, no rod is required.
How long does an anode rod last?
An anode rod typically lasts from three to five years, depending on the water quality in the tank.
