Life of a water heater
I have a 7-year old A.O.Smith 40 gal water heater. Works fine, but I've
only drained it out once about 4 years ago. Assuming that that water heaters last about 8-10 years, I have some questions - how often should I be draining and cleaning it out? - does regular draining help prolong its life? - how does one tell that it's ready to break (instead of finding out when the basement is flooded with hot water)? Thanks Mark Sabatini |

Life of a water heater
As was already pointed out, you should check the anode rod every few
years. This is a sacrificial anode that is there to corrode away instead of the tank. The rate of decay of the rod depends on the content of the water, temp, any stray electrical current, etc. If you replace the rod before it's gone, that will extend the life of the tank. And also, as was pointed out, the life of an electric tank is typically a lot longer than that of a gas one. |
