The Clack System Controller Kit is an advanced control solution designed to operate duplex and multiplex water softening systems, allowing up to eight Clack control valves to work together as a coordinated system. It provides efficient management of multiple softener vessels, making it ideal for commercial, industrial and high-demand water treatment applications.

Designed for flexibility, the System Controller supports Clack 1", 1.25", 1.5" and 2" control valves. It manages system operation, including alternating duty and standby vessels, regeneration sequencing and demand-based control, helping maintain a continuous supply of softened water.

The controller features a user-friendly microprocessor interface with a clear front panel displaying the time, day, regeneration countdown, current flow rate and total water usage. LED indicators provide convenient monitoring of online, standby and regeneration status.

Additional functionality includes Ethernet connectivity, Modbus communication for building management system integration, USB data export for system diagnostics and programming, and battery backup for time retention. Two fused SPDT relay outputs are also provided for external control applications.

The kit is designed to simplify installation, with Molex circuit board connectors and the ability to power connected valves directly from the System Controller, eliminating individual plug-in power supplies for compatible valves.

What Is WRAS Certification?

WRAS certification stands for Water Regulations Advisory Scheme approval, and it’s a trusted mark that shows a product complies with the UK's water supply regulations. 
It means the materials and components used won't contaminate your drinking water and that the product is built to a high standard of safety and quality. It’s especially important for anything connected to the mains water supply, whether you’re fitting out a commercial site or upgrading your home system. 
All of our products are WRAS certified as standard, so you can have complete confidence they’re fully compliant, reliable and built to last. If you're ever unsure about what's required for your setup, we're always happy to advise.

This approach allows our pricing to remain clear and consistent for both trade and domestic customers, while ensuring the correct VAT amount is applied to every order. You will always be able to review the full order total, including VAT, before completing your purchase.

How Often Should I Replace My Water Filter?

In the UK, most domestic and commercial water filters should be replaced every 6 to 12 months, depending on the type of filter, water quality, and usage levels. Here's a quick breakdown:


• Sediment Filters (used in pre-treatment): Every 6 months or sooner if water flow drops noticeably.


• Carbon Filters (for taste, odour, chlorine): Every 6 to 12 months.


• Reverse Osmosis Filters: Prefilters every 6–12 months, membrane every 2–3 years.


• UV Lamps: Annually (bulb may still light after a year but won't provide effective disinfection)


• Limescale Filters: Cartridges usually last 6–12 months, depending on hardness and flow.


If you're dealing with high sediment levels, hard water, or heavy usage (like in a commercial setting), you may need to replace filters more frequently. Always follow the manufacturer’s guidance, and if in doubt, we’re happy to advise based on your system and setup.
