Abstract
There is provided a water delivery system that includes, hot and cold water lines that are for feeding hot and cold water to respective hot and cold water fixtures, a water heater having a cold water input and a hot water output, a water circulator for pumping water from the hot water outlet to the hot water fixture, a bypass line that couples between the water circulator and the cold water input and at least a first check valve constructed and arranged in the bypass line for selectively directing hot pumped water via the water circulator to the cold water input to the water heater while preventing flow in an opposite direction toward the water circulator. A second check valve is disposed in the cold water line for selectively directing cold water from the cold water line to the cold water input to the water heater while preventing flow in an opposite direction toward the cold water line.
