Lately my hot water cools down before I'm finished showering. It never
used to do this. Wondering if it is a symptom of a fading element. The
heater is a 30gal Ruud Pacemaker Ruudglass but can only estimate age
to be approx. 30yrs.
A tankless heater will be its replacement. Is it time??

I agree with the sediment in the bottom. Also quite probable that one of
the two elements has died.

An element replacement does not justify a new heater but 30 years old does
in my mind.
