Clack's WS1 Automatic valve is a state-of-the-art control head designed for residential and commercial applications requiring flow rates up to 27 GPM(6.1 m3/hr). It has a backwash ability capable of servicing up to 22" diameter tanks.
The valve acts as a primary center that directs and regulates all cycles of water softening or filtration. It can be set to perform down flow regeneration or simply backwash and rinse. The valve comes in different program versions and is controlled by a solid state microprocessor with front panel setting and screen display. The WS1 has 9 injector sizes to choose from for different draw rates.
Clack valves also provide a double backwash ensuring the media is properly rinsed of all residue and chemicals. Clack valves are the only valve that provides this option. There is no substitute for a quality product. We at Home Water Pros only use the #1 rated parts. Customer satisfaction is our #1 goal.
Do not be fooled by a smaller valve as the flow rates are approximately 13 GPM. Lower flow rates means less water is available at the time your family needs it the most.
