What it is

The Worcester Bosch 87161034240 is a domestic cold water (DCW) inlet isolation valve used on Worcester Bosch gas-fired appliances. It sits on the incoming cold water feed and allows that supply to be shut off so the appliance can be drained, serviced or have components replaced. It is a Worcester-branded spare valve assembly.

Signs this part needs replacing

  • Water weeping or dripping from the valve body or spindle
  • The incoming cold water supply cannot be fully shut off when the appliance is being serviced
  • The valve handle is stiff, seized or turns without changing the flow
  • Scale or corrosion visible around the valve body or its connections
  • Reduced cold water flow reaching the appliance

Before you order

  • Check the GC number and the appliance serial plate to confirm this valve suits your model.
  • Cross-reference the alternative numbers 1014211 and WB87161034240 against the part being removed.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
