Why does my water heater run out of water quicker than it used to?

Over time storage tank water heaters accumulate sediment and lime deposits. If these deposits are not removed periodically they will displace space in the tank and decrease the amount of water that can enter the tank when it refills. It’s important to drain and refill your water heater once year. This will also help your water heater last longer, as mineral deposits can corrode the bottom of the tank if left alone.
