What it is

The Worcester Bosch gas cock is an isolation valve fitted on the gas inlet of the appliance, allowing the gas supply to be shut off at the boiler for servicing, safety checks and component replacement. It is manufactured by Worcester Bosch and belongs to the Greenstar and British Gas badged boiler families. The valve forms part of the gas train, sitting upstream of the gas valve assembly, and its job is to give a reliable, resealable shut-off point on the appliance.

Signs this part needs replacing

  • Gas smell around the boiler casing or at the gas inlet connection
  • The valve spindle is stiff, seized or will not turn through its full travel
  • The gas supply cannot be fully isolated at the appliance during servicing
  • Visible corrosion, cracking or weeping at the valve body or its connections
  • A leak detection test at the gas cock shows a drop in pressure
