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
