Nashville's municipal water supply measures between 80 and 120 parts per million of calcium carbonate, classifying it as moderately hard to hard water. This mineral content accelerates sediment accumulation at the bottom of tank water heaters, reducing heating efficiency and creating hot spots that weaken the steel lining. Over time, this sediment hardens into a concrete-like layer that insulates the heating element or burner from the water, forcing the system to work harder and shortening its lifespan. Homes in older neighborhoods with galvanized supply pipes face even faster buildup due to scale deposits that flake off and settle in the tank. Regular flushing helps, but many Nashville homeowners do not realize their water heater needs this maintenance until it is too late.
