Abstract:
A method of retrofitting a pre-existing reverse osmosis system having at leasta reverse osmosis membrane vessel, and a purified water storage tank, where water from a source of water is converted into purified water at a first outlet port, and into waste water at a second outlet port, of the reverse osmosis membrane vessel, the retrofitting method comprising: first-disconnecting a flow of water from the source of water from any flow-connection to an inlet port of the reverse osmosis membrane vessel; and first-inserting in-line the disconnected flow of water an integrally-packaged first sub-assembly, having a first sub-assembly input port flow-connected to a pump flow-connected to a solenoid valve flow-connected to a pressure gauge flow-connected to a first sub-assembly output port, so that the first sub-assembly input port becomes flow-connected to the source of water, and so that the first sub-assembly output port becomes flow-connected to the inlet port of the reverse osmosis membrane vessel.
