What it is

The VALVE DCW IN is a domestic cold water inlet isolation valve manufactured by Worcester Bosch, part number 87174052730. It is fitted on the cold water supply into the appliance and allows the water feed to be isolated for servicing or repair. It is listed in the isolation valves category for Worcester Bosch gas boiler spares.

Signs this part needs replacing

  • Water weeping or dripping from the valve body or spindle
  • The valve will not shut off fully when closed, so the water feed cannot be isolated
  • Persistent dampness or scale marking around the valve after the supply is turned back on
  • The operating handle or spindle is stiff, seized or no longer turns the valve

Before you order

  • Check the part number on the existing valve or the appliance documentation against 87174052730
  • Confirm the appliance model is the Worcester Greenstar Highflow 440
  • Identify that the fault is with the cold water inlet isolation valve and not another valve or connection on the appliance
