Abstract: A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

Abstract: A top fill water reservoir system that allows the reservoirs to be filled without waiting for a reverse osmosis (RO) filter to produce enough water to fill the system and avoids the need for a service worker to remove the system from the cabinet, or wait for RO filtration, to fill the reservoirs. The top fill water reservoir system comprises a drinking reservoir adapted to store and dispense drinking water. A supply reservoir in fluid communication with the drinking reservoir and adapted to feed water into the drinking reservoir and receive water from a reverse osmosis (RO) filter. An overflow tube adapted to connect an upper portion of the drinking reservoir to the supply reservoir and feed overflow water from the drinking reservoir to the supply reservoir.

Abstract: The improved water purification system includes a water purification unit having a tap water inflow port for receiving a tap water inflow from a water supply system to produce relatively purified water and a brine water outflow having impurities concentrated therein. An RO filter having an RO membrane separates relatively unfiltered water flow into purified water and the brine water outflow. A flush flow activation chamber fluidly coupled to the brine water outflow includes a plunger for substantially occluding brine water outflow through the brine outflow port when seated, and substantially permits brine water outflow to exit the purification unit through the brine outflow port when unseated. Accordingly, the activation chamber generates back pressure within the water purification system to flash flow tap water inflow into the purification unit and through the RO membrane when the plunger moves from being seated to unseated, thereby substantially refreshing said RO membrane.

Abstract: A water purification system that allows for bypassing one or more stages of purification during periods of high demand. Bypass can be selectively implemented as a function of fluid particulate levels and/or reservoir level.

Abstract: The water purification system for flow-coupled installation with a tap water inflow for producing a relatively purified water outflow includes a purification unit having a tap water inlet port for receiving tap water inflow and a purified water outlet port for dispensing purified water outflow from said purification unit. A particulate catalyst retained within the purification unit is in flow through relation relative to said the water inflow and purified water outflow and catalyzes contaminants as the tap water inflow travels through the purification unit. A spring agitator particulate agitator associated translates vibration to the particulate catalyst for substantially preventing channeling therein during relatively slow tap water inflow through the purification unit.
