The Clack WS1 Meter Assembly V3003-05 is used on metered Clack WS1 water softener and filtration control valves. The meter assembly measures water flow through the valve and sends usage information to the control board, allowing the system to calculate remaining capacity and regenerate when needed. This part is commonly replaced when a metered Clack valve is no longer counting gallons properly, the display is not showing water usage, or the system is not regenerating based on demand as expected. Clack lists part V3003-05 as the WS1 Meter Assembly, 22 in. in its current service parts documentation.
