Raritan 12/20 Gal Magnesium Water Heater Anode

The Raritan magnesium anode is a replacement corrosion-protection rod for compatible 12- and 20-gallon water heaters. Magnesium is intended to sacrifice itself gradually to protect the metal inside the water-heater tank. Regular inspection can help catch an exhausted anode before tank damage occurs.

The rod measures 16-1/8 in long and has a stainless steel fitting. It is made for the stated Raritan heater capacities rather than every marine water heater. Check the model and available service clearance before choosing a replacement.

Drain and isolate the water heater before removing an old anode. Inspect the old rod for depletion and reinstall according to the heater’s service instructions. The package contains the replacement anode rod and fitting, not a water heater. Checking for corrosion at the fitting during replacement can also help catch developing service issues.
