What it is
The Worcester Bosch 8716118464 is a double check valve that forms part of the isolation and flow-control assembly on Worcester Bosch gas appliances. It allows flow in one direction only, preventing water or gas from travelling back through the circuit and helping the appliance maintain dependable performance. The valve is supplied as a single unit and carries a 1 year manufacturer guarantee.
Signs this part needs replacing
- The isolation valve no longer shuts off flow when closed, so the appliance cannot be isolated properly for servicing.
- Water weeps or drips from the valve body or from the connections around it.
- Debris or scale stops the check valve seating, allowing backflow through the circuit.
- The spindle is stiff, seized or will not turn through its full travel.
- Corrosion or discolouration is visible on the valve body or union.
Before you order
- Check the GC number and appliance serial number against the compatibility list to confirm the valve suits your model.
- Confirm the part number on the existing valve matches 8716118464 or one of the alternative numbers listed below.
- Inspect the surrounding seals and washers while the valve is removed and replace them if they are worn.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
