What it is

The Black Nut & Spindle Kit is a Glow-worm service component for the diverter valve assembly. It provides the nut and spindle arrangement that operates the diverter valve, directing water between heating and hot water modes. It is listed for use on the Betacom range of gas boilers.

Signs this part needs replacing

  • Water weeping or dripping from the diverter valve spindle area
  • Visible corrosion or pitting on the nut or spindle
  • Stiff, sticking or seized diverter valve operation
  • Poor hot water performance or unstable domestic hot water temperature
  • Scale or debris build-up restricting spindle movement

Before you order

  • Confirm your boiler model is a Betacom 24C or Betacom 30C
  • Check the GC number on the appliance data badge against your model
  • Verify the fault is at the diverter valve nut and spindle before ordering
  • Confirm the part number 0020119266 matches the component removed
