Patent ID: 7240852

Claim:
A water flushing system comprising: a drinking fountain spout; a flow controlled passage having an inlet adapted for fluid connection to a pressurized water distribution system and an outlet adapted for fluid connection to the drinking fountain spout; a drinking fountain spout valve disposed along the flow controlled passage for selectively permitting and prohibiting the flow of pressurized water through the flow controlled passage and into the drinking fountain spout; a discharge passage branching from the flow controlled passage upstream of the drinking fountain spout valve; a discharge valve disposed along the discharge passage for selectively permitting and prohibiting the flow of pressurized water through the discharge passage; and a programmable controller for regulating the flow of pressurized water through the discharge passage by activating and deactivating the discharge valve on a predetermined timed basis, whereby stagnant water can be flushed from the flow controlled passage to maintain water quality in the flow controlled passage as delivered to the drinking fountain spout.
