What it is

The Worcester Bosch 8716118204 is a gas cock valve, an isolation valve that sits on the gas supply path of the appliance. It allows the gas feed to be shut off at the boiler so that servicing, safety checks and component replacement can be carried out without disturbing the upstream supply. The part is used across the Worcester Bosch Greenstar Highflow CDi ErP range of gas boilers.

Signs this part needs replacing

  • A smell of gas around the boiler or at the valve body, indicating a leak at the spindle or connections.
  • The valve spindle is stiff, seized or will not turn through its full travel.
  • The gas supply cannot be fully isolated at the boiler during servicing.
  • Visible weeping, staining or corrosion around the valve body or its joints.
  • The valve has been disturbed or damaged during previous work on the gas line.
