Again, my new 102-year old house (closing will be end of September). I had it inspected and one comment in the inspection report is that the hot water heater is really old and will need to be replaced. It's working fine, but it's 22 years old, a 40-gallon tank. The inspector says it normally has a life of about 10 years.
I know that when a water heater "starts to go", sometimes you get water leakage around the bottom. Right now there is no such leakage and everything seems fine. My question is, when it "starts to go", will it DEFINITELY start leaking, or is it possible that it will just burst or something equally violent? If it will start leaking when it needs to be replaced, then I can just monitor it weekly to make sure there's no leaking, and when I see leaking, I can then replace it. But if it's a possibility that something major could happen just out of the blue, I'd probably better replace it now since it's so old.
