This FAQ explains what Clack valves are, how to select the right size, and the difference between Time Clock and Metered valves. Discover servicing schedules, where to find spare parts, and how Dowdens assists with programming and repairs.
Clack Control Valves are advanced, automated valves used in residential, commercial, and industrial water treatment systems. They regulate the flow of water during service and regeneration cycles for water softeners and filters. Known for their durability and ease of programming, models like the WS1, WS1.25, and WS2 are industry standards for consistent performance.
Sizing depends on your flow rate requirements and pipe size.
Time Clock (TC): Regenerates based on a set number of days (e.g., every 3 days), regardless of water usage. This is often used for filters that require regular backwashing to prevent media fouling.
Metered: Uses a flow meter to track water usage and regenerates based on the volume of water treated. This is generally more efficient for water softeners, as it saves salt and water by only regenerating when necessary.
While Clack valves are designed for longevity, we recommend a preventative maintenance check every 12–24 months, depending on water quality. High levels of iron or sediment may require more frequent cleaning of the injector screen and stack assembly to prevent wear.
