An instant hot water dispenser, like any water heater, has a limited life and will eventually fail. To avoid possible property damage, this instant hot water dispenser should be regularly examined for leakage and replaced when necessary. A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage.
