Clack Injectors WS1 and WS1.25 Valves V3010

The 10440000146 is a replacement injector for the V3010 brine assembly fitted to Clack WS1 and WS1.25 control valves. The injector uses a venturi effect to draw brine from the salt tank into the resin bed during regeneration, and its precisely sized orifice determines how much brine is pulled through and over what time. If regeneration is no longer drawing brine properly, or the injector is clogged or worn, this genuine-spec part is stocked by WrekinWater.

Technical specifications

Symptoms that mean you need this part

• The softener is regenerating but no brine, or very little, is being drawn from the salt tank
• Hard water is returning between salt top-ups because regeneration isn't recharging the resin properly
• The injector screen is visibly clogged with sediment, resin fines or scale when inspected
• The wrong injector size was fitted after a tank or resin volume change, giving a weak or overly fast brine draw

Why it fails / why it matters

As water flows through the injector during the brine draw stage, it passes through a narrowed throat that creates a vacuum, pulling brine up from the salt tank and into the resin bed. The orifice is sized precisely for the valve and system it's fitted to, so even small amounts of sediment, resin fines or scale lodging in the throat can restrict or stop the draw altogether. A worn or damaged injector can also lose its shape and no longer generate enough vacuum, leaving the resin bed under-recharged and hard water able to slip through between services.

Why buy this from WrekinWater

WrekinWater has supplied genuine-spec Clack parts to installers and DIY customers for over 15 years from its Bettisfield, Shropshire base, and stocks the injector range for WS1 and WS1.25 valves so you can match the correct part rather than guess. Orders are processed quickly and the business is rated Excellent on Trustpilot, which matters when your softener isn't regenerating properly.

How to fit it

1. Isolate the softener at the bypass valve before working on the brine valve assembly
2. Remove the injector cap from the valve body, usually secured by a small screw or bayonet fitting
3. Withdraw the old injector and its screen, checking both for cracks, wear or blockage
4. Clean the injector cavity and fit a new o-ring if the old one is worn or flattened
5. Fit the new V3010 injector, making sure the size matches your original specification for the valve and tank
6. Refit the cap, run a manual regeneration, and check brine is being drawn from the salt tank as expected
