What it is
The Worcester Bosch 87161567520 is an isolation valve for the domestic cold water (DCW) inlet of the appliance. It sits on the incoming cold water supply and allows the flow to be shut off at the boiler so that servicing, draining or component replacement can be carried out without isolating the whole property. It is used across the Worcester Bosch SI RSF combi range and the related British Gas-badged units.
Signs this part needs replacing
- Water weeping from the valve body or around the spindle
- Dripping at the joint where the valve meets the incoming pipework
- The handle turns but the cold water supply does not shut off
- A stiff or seized handle that will not move by hand
- Damp staining, corrosion or limescale trails around the cold water inlet
