Q: How often should you replace an anode rod?

• <div><p>Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. </p></div>

Q: Are tankless water heaters better than traditional water heaters?

• <div><p>There are <a href="https://www.angi.com/articles/what-are-pros-and-cons-tankless-water-heaters.htm">pros and cons to tankless water heaters</a>. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact.
