ABSTRACT:
The invention is directed to a water treatment system including a treatment tank having an ion-exchange mineral bed or filter bed therein, and a valve head assembly disposed on top of and in fluid communication with the treatment tank. The valve head assembly includes a passage for allowing a flow of fluid through the valve head assembly, a vacuum pressure creating device disposed within the passage, a drain disposed within the passage and at a downstream side of the vacuum pressure creating device, and a valve disposed within the passage and at a downstream side of the vacuum pressure creating device. The valve is movable to an open position and a closed position for allowing fluid flow through the vacuum pressure creating device, whereby a portion of fluid flows through the drain and a lesser remaining portion of fluid flows through the valve when the valve is in the open position.
