I was in an apartment with one that sprung a leak in 2010 or so. It was made in 1989. Bought a house in 2016 with a Rheem that was made in 2001. Replaced it in 2019 before it showed any signs of leaking.
Both of these were gas on city water in central Ohio. So 20 years if you're willing to risk it. 15+ if you're risk averse.
