Flushing the Water Heater



Most people have never thought to flush the water heater.  Flushing is done by draining the water tank and then sending more water through it to finish cleaning out the sediment, dirt and rust that have accumulated in the tank throughout the years.  There are several good reasons to flush your hot water tank on a regular basis.



First, flushing the tank at least once a year helps prevent the growth of bacteria in the sediment.  This will keep your water safe to bathe in.  It will also keep it from developing a rotten egg smell.  In addition, all of the salts and minerals in the sediment will dissolve into your water.  The chlorine in the water may also react with the sediment and produce new chemical compounds.



Another benefit to regular flushing is the additional hot water you will have.  When sediment builds up on the bottom of the tank it displaces water, leaving you with less hot water to do dishes or take showers.  The amount of sediment that can build up in a water tank is astonishing.  It can take up several inches of the tank!  If you have an older hot water tank that has never been flushed and are getting less hot water than you once did, excessive sediment may be the reason.



The third reason you should flush your tank is energy savings.  When sediment builds up on the bottom of the tank the heater has to work harder and uses more energy to heat the water.  This is true for both electric and gas water heaters.  Finally, flushing a hot water heater regularly will make the unit last longer.  Too much sediment can strain the heating element to the point of early breakage.
