This is probably the most used and most neglected appliance in our homes. It is spring time and a few minutes of your time guys and gals will prevent some "cold" moments. All you need to do is attach a garden hose to the drain connection at the bottom of the tank. Put the hose into a floor drain etc., note do not run this water onto your lawn, it will kill it. May be good if you are trying to get rid of some weeds. Turn the valve on and let it run for about 5 minutes. You will be surprised at what comes out. This is the sediment that builds up over time from our water and needs to be flushed out. Left for years over time this is what rusts out the bottom and starts those darn little leaks that cause the whole unit to be replaced. This will add years to your tank. This should be done on a regular basis, at least 4 times per year. It's a lot more work to replace this appliance than most others and its one you don't like to be without. Happy Flushing.
