Patent ID: RE40310

Claim:
A water purification system for purifying water flowing through a water flow path between an inlet and an outlet, the system comprising: a water purification device in a water flow path having an outlet, said water purification device having at least one interior volume; a purification medium positioned within the interior volume; a pump for moving water through the purification medium; a flow control system for controlling a volume of purified water dispensed from the outlet of the water flow path, the flow control system including an input device configured to allow a user to input a desired volume of purified water to be dispensed from the outlet of the water flow path during a dispense cycle and a sensing device operable to generate a signal used to determine a volume of purified water dispensed from the outlet of the water flow path; and a flow regulation device coupled with the flow control system and operable to stop the discharge of purified water at the outlet of the water flow path when the desired volume of purified water has been dispensed from the outlet of the water flow path . ; and wherein the flow control system is configured to execute a system leak checking routine to determine whether purified water is leaking from the system based at least in part on the signal from the sensing device used to determine a volume of purified water dispensed from the outlet of the water flow path and disable the pump when a leak is detected.
