Claim Text:
1. An automatic hot water recovery apparatus that includes an elastomeric bladder positioned inside a vessel and configured to be connected between a cold water supply line and a hot water heater and wherein the elastomeric bladder is configured to be expanded by water flowing from the cold water line toward the hot water heater and wherein when the elastomeric bladder is fully expanded the water flows through a one way check valve into a dip tube and through a small tube within the dip tube and wherein the elastomeric bladder is configured to contract when the water stops flowing toward the hot water heater and the contracting causes water from the hot water heater to be pulled back through the small tube but not through the dip tube, so that the small tube pulls the water from a lower portion of the hot water heater.
