Clack WS2CI Softener Meter Controlled Valve 2" (Meter Assembly Included) V2CIDMD-05

The Clack WS2CI Softener Meter Controlled Valve (V2CIDMD-05) is a complete 2in commercial control head supplied with its meter assembly included, and WrekinWater stocks it as a genuine replacement for larger commercial and hospitality softener installations running Clack WS2CI systems across the UK. Being meter controlled, it initiates regeneration based on measured water use rather than a fixed clock, giving efficient, demand-based operation for sites where consumption fluctuates through the week.

Technical specifications

Symptoms that mean you need this part

• The softener regenerates inconsistently against actual measured water use, too often or not at all
• The meter seems to be misreading flow compared with the site's known consumption
• Hard water is reaching taps and appliances despite the valve appearing to cycle normally
• The control head's display, electronics or piston mechanism is unresponsive or faulty

Why it fails / why it matters

The meter turbine, drive electronics and piston assembly inside a commercial WS2CI valve are under continuous load tracking water use and triggering regeneration at the correct point, and sustained high-flow commercial duty wears the meter bearings, seals and internal mechanism more quickly than domestic-scale use would. Once the meter falls out of calibration, the piston sticks, or the electronics fail, the softener either wastes salt and water on unnecessary regenerations or fails to regenerate when it should, letting hard water through — and given the scale of the valve, a full head and meter replacement is the standard fix.

Why buy this from WrekinWater

WrekinWater has served more than 50,000 customers over 15 years from its base in Bettisfield, Shropshire, and stocks genuine Pentair Fleck, Autotrol, Clack and Kinetico parts including this commercial WS2CI meter valve with meter assembly included, so installers replacing larger control heads can order the correct part with confidence. As UK Company No. 11000488 and rated Excellent on Trustpilot, the team can help confirm compatibility and site requirements before you commit to a purchase at this scale.

How to fit it

1. Have a competent water treatment installer confirm the existing tank, riser and pipework are compatible with this replacement valve and meter assembly before ordering
2. Isolate the water supply and fully depressurise the softener, placing the system in bypass if fitted
3. Disconnect the drain line, brine line, inlet/outlet pipework and power supply from the existing 2in control head
4. Remove the old valve from the resin tank, taking care with the riser tube on a commercial-size vessel
5. Fit the new V2CIDMD-05 valve with its included meter assembly, ensuring the riser tube seats correctly and all connections are aligned before tightening
6. Have the installer reconnect pipework and power, then commission the valve — setting hardness, capacity and meter calibration — with a full test regeneration before the softener returns to service
