RV Anode Rod to anti fouling your solar Water Heater tanks
Most water heater tanks are steel with a thin glass lining to protect the metal from corrosion. Since the lining eventually cracks, tanks have a second line of defense against rust, a long anode rod that attracts corrosive elements in the water. When the rod itself becomes so corroded that it can no longer do its job, the tank soon rusts out, leaks and needs replacement. However, if you replace your anode rod before it fails, about every 3-5 years(A magnesium anode), you can double the life of your water heater.
The best time for water heater anode rod replacement is when the steel core is exposed more than 6" either from the bottom or the top; when the middle of the rod is exposed or if diameter is less than half the original size.
Use these steps to replace or remove the water heater anode rod:
- Shut off the power to the heater.
- Turn the cold water supply off.
- Recommendation is to drain out few gallons from the drain valve at the bottom of the heater.
- Drain the heater using the garden hose and route to the open drain. Open a nearby hot water tap to vent heater for draining. Drain to the point below the outlet connection nipple.
- Close drain spigot and remove the hose.
- Remove the water heater anode rod using the appropriate tool.
Removing a water heater anode rod is a simple do-it-yourself home project, where you can use a ratchet wrench to unscrew the old and screw in a new anode rod. Be sure to use Teflon tape on the fitting threads, so it can seal tightly. If only checking, be sure to clean the calcium-carbonate build-up. Buying online is the most convenient way, especially if looking for something specific, like Suburban anode, zinc alloy anode or flexible magnesium anode rod.
