Yes - when we moved into our house in 2005, we heard the occasional belching and growling. At that time , the water heater was about 10 years old. I tried on 2 or 3 occasions to drain it, but with no success - nothing would come out. I knew I'd have to unscrew the hose bib to fix the problem, but by then my garage was storing so much stuff I didn't want an uncontrolled flow coming out of the heater soaking everything.
We just sold the house last week, and I'll wager the new owner will have to replace it within months . . . . if she isn't broke from replacing the AC unit of the same age - it's on its last legs, too.
