What it is
The Vaillant 0020010296 is a service cock manufactured by Vaillant for use within its heating appliances. It is an isolation valve that sits on the water circuit, allowing the supply to be shut off at the appliance so that servicing, component replacement or pressure work can be carried out without draining the whole system. The valve body and connection are built to the manufacturer's specification for the appliance range it serves.
Signs this part needs replacing
- The valve no longer isolates the water supply fully when closed, leaving water passing through during servicing
- Water weeps or drips from the spindle or around the valve body
- The handle or spindle has seized, is stiff to turn, or turns without operating the valve
- Scale, corrosion or staining is visible around the body or connection
- The valve has been damaged during previous work and will not seal again
Before you order
- Check the model and GC number on the appliance data badge and confirm the part number 0020010296 matches the valve currently fitted
- Inspect the connection and any washer or seal on removal, as these may need renewing at the same time
- Confirm the valve position and orientation on the appliance before fitting, as service cocks are not interchangeable between positions
