Many manufacturers recommend water heater anode replacement every two to four years depending on the hardness of the water that passes through the tank and the quality of the water heater lining.
Many homeowners save money by purchasing the water heater on their own before installing it instead of purchasing a package deal of the water heater and installation services. Removing and disposing of an old water heater can add up to $500 to the overall cost. Most water heaters come with a warranty that averages 8-12 years in length.
