The present invention provides an apparatus and method for aeration in a filter system. The present invention provides an air injection adaptor for coupling between a filter tank and a valve controller. The air injector adaptor includes an unfiltered water inlet adapted for coupling to the unfiltered water outlet of the valve controller; an unfiltered water outlet in fluid communication with the unfiltered water inlet of the adaptor, the adaptor unfiltered water outlet adapted for coupling to the opening at the upper end of the tank; a filtered water inlet adapted for coupling to the upper end of the stand pipe; a filtered water outlet in communication with the filtered water inlet of the adaptor, the adaptor filtered water outlet adapted for coupling to the filtered water inlet of the control valve; an air source inlet adapted for coupling to a regulated air source; an air source outlet in communication with the air source inlet and adapted for opening into the upper end of the tank; and a vent, the vent having a vent inlet and a vent outlet in communication with the vent inlet, the vent inlet opening into the upper end of the tank.

Apparatus for aeration in a water filter system

A countertop faucet assembly adapted to be secured over a hole in a countertop without requiring access to the area below the countertop. A base subassembly of the countertop faucet assembly is secured to the countertop and a faucet and cap assembly is thereafter secured to the base subassembly.

Countertop faucet assembly

A self-contained monitoring system for monitoring the operating condition of a fluid treatment device. A housing provides a pair of flow passages, one for liquid supplied to, and the other for liquid treated by the fluid treatment device. Separate pairs of electrodes are provided, with one pair of electrodes extending into one of the flow passages and the other pair extending into the other flow passage. The conductivities between each pair of electrodes are provided as signals to an electronic circuit contained within the housing which provides electrical output signals indicative of the operating condition of the fluid treatment device based upon the conductivity of the supplied and treated fluid flows.

Self-contained reverse osmosis electronic monitoring system

A reverse osmosis water processing and storage system having a prefilter, reverse osmosis membrane assembly, and a storage volume contained within a first tank. The prefilter and reverse osmosis membrane assembly are located within a second tank which is in turn located within an expandable bladder which is received within the first tank. Processed water is stored in the volume provided between the second tank and the expandable bladder.
