Do you know what the average life span of a water heater is? Do you know how much life is left in your water heater? If not, don't worry! The average water heater should last somewhere between 8-12 years. Are you getting close to this amount of time with the same water heater? If so, you might want to start thinking about replacing your current for a new one! Even the most meticulously cared water heater can give out at any time, meaning the smallest of leaks can become a huge problem! If yours is a decade or more old, it might be time to start shopping around!
