What it is
A 28mm isolation valve supplied by Worcester Bosch under part number 87186804180. It sits on the pipework of Greenstar FS CDi Regular floor-standing boilers and allows the water circuit to be shut off locally so that servicing, draining or component replacement can be carried out without emptying the whole system. The valve body and connections are sized for 28mm pipework.
Signs this part needs replacing
- Water weeping from the valve spindle or the gland area when the handle is turned.
- The handle turns but the valve will not shut the flow off completely, so the circuit cannot be isolated.
- The handle is stiff, seized or has snapped off, making the valve unusable.
- Damp or corrosion staining around the compression nuts or the valve body.
- A visible drip from the valve during a service or drain-down.
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the valve suits your model.
- Confirm the existing valve is 28mm and matches the pipework on the appliance before ordering.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
