My husband just put in a new water heater for our home. I was told to preserve the longevity of the new heater; you should drain it once a year ... is that correct or helpful? And is there anything else we can or should do as preventive maintenance to preserve the life of the water heater?

Hi Janna, I get calls on this all the time! I don’t think draining is the word I would use, I would say “flush” the heater. To do that, you would just hook up a hose at the bottom of the heater and open that hose bib on the heater. I would take the other end of the hose and discharge the water into a floor drain for approximately 10 minutes or until you see clear water. Draining the heater is misconstrued by shutting off the heater, draining the water, and then opening all valves and putting it back into service. The problem with draining the heater is this; once the water is shut off, the water is air locked in the heater and it could take a day to drain. We want to use the water pressure from the municipality to flush the heater, so we don’t want to shut off the valves on the heater. We want to put the hose on the hose bib and blow the accumulated line rust, etc. out of the heater. As for other things you can do there really isn’t much else, we can do except to keep the area clear of clutter around the base of the heater. Thanks for the question Janna.
