When is the last time you flushed you water heater? If you're like most people, your answer is, "I'm supposed to flush my water heater?"
Because your water heater is essentially a water storage tank, while the water is being held in the tank, sediment naturally occurring in just about every source of water settles to the bottom of your tank. Over time, this sediment builds up, and can effect the normal operation of your water heater.
While there are not typically symptoms of a water heater that needs flushing, neglecting to flush you water heater regularly affects the internal components of your water heater and shortens its lifespan. It also can affect the efficiency of your water heater, requiring more energy to operate (higher costs!).
