our water heater was replaced a couple of years ago. it wasnt leaking, but the hot water was not lasting long enough AND it began making a lot of "popping sounds" inside of the tank. it was going on almost 18 years of having the same water heater. we bumped up to a larger tank and bought a rheem when this began happening.
