You could check the anode and replace it if necessary. The anode is there
to protect the glass. Once it dissolves the water starts on the glass.

I'm looking for some advice on when to replace a water heater. Obviously
when it ruptures and water goes all over your basement is a good time, but
prior to that, what is a good rule of thumb. The reason I'm asking is
that our local gas company is offering a $200 rebate to customers for
their purchase and installation of a new water heater. Our 50-gal water
heater appears to be functioning just fine but it's 10 years old. From
what I can tell it has a 5 year warranty from Rheem. I'm wondering if it
would be wise, or overly cautious, to replace it at this point. Any
advice? Thanks.
