    Have a 12 year old Rheem 65 gal electric WH. Came home from vacation and water is not as hot as before (can take a shower on hot only now) and doesn’t last as long (we could both take showers before and now all gone after one shower).

    I figured one of the heating elements was burned out, but when I took off the cover plates this unit only has a single 5500 W element. The upper plate just has a threaded plug in it.

    No sediment evident in tank when I flushed it.

    Should I replace the element? Do I need to replace the thermostat too? Is it worth it to get a whole new tank?

    Hello: I’ve two words for you… dip tube — anode. (OK, that was three words)

    Yours, Larry

    ps. A broken dip tube will allow cold water to mix with hot, giving less hot water. At twelve years, your tank wants a new anode. Check for cross connection in the plumbing also. See tanklets.
