Abstract: A water purification system includes a storage tank, a prefilter, a reverse osmosis element, a deionization module, a feedwater connection, a brine discharge line, and an electronic memory panel, all of which are incorporated within mounted or mountable on the underside of a kitchen sink. The system also includes a long reach faucet and a product water connection connects the storage tank to the long reach faucet from which the storage tank discharges purified water.

Abstract: An electronic memory panel assembly controls the operation of a portable water purification system which has a reverse osmosis unit having an inlet. The assembly includes a solenoid device with piping having an inlet end fitting for attachment to a source of water to be purified, an outlet end fitting for attachment to the inlet of the reverse osmosis unit, a normally closed valve in the piping, and a solenoid having terminals which when activated will open the valve to cause automatic operation of the purification system. The assembly also includes a control device for automatically controlling the solenoid in accordance with predetermined criteria.
