What it is

The Vokera 20040979 is an isolation cock used on Vokera Verve gas boilers. It forms part of the boiler's isolation valve arrangement, allowing the flow through the relevant pipework to be shut off for servicing or component replacement. It is listed by Vokera under isolation valves within the boiler spares range.

Signs this part needs replacing

  • Visible water weeping or dripping from the valve body or spindle
  • The handle turns stiffly, binds, or will not move through its full travel
  • The valve fails to shut off flow when closed, so the section cannot be isolated
  • Corrosion, scale or staining around the valve body or gland
  • A persistent drip from the spindle gland after the valve has been operated

Before you order

  • Confirm the boiler model against the fitment list above
  • Check the GC number on the appliance data badge matches the boiler you are working on
  • Verify the existing valve's position and function on the appliance before removal
  • Confirm the part number 20040979 against the manufacturer's parts list for your model
