What it is
The Vaillant Schrader valve, part number 10027681, is a spring-loaded valve core used on Vaillant Arotherm and Arotherm PLUS air-to-water heat pumps. It provides a sealed service access point on the refrigerant circuit, allowing pressure testing, charging and evacuation without loss of charge once the service tool is removed. This part is supplied as a pack of five valves.
Signs this part needs replacing
- Refrigerant loss or a persistent pressure drop traced to a service port
- Visible refrigerant oil staining around the Schrader valve
- A valve core that will not seal after a service hose is removed
- Audible hissing or bubbling at the service port during operation
- Difficulty obtaining a stable pressure reading when gauges are connected
Before you order
- Confirm the appliance model and variant against the fit list above
- Check the number of service ports requiring attention, as the pack contains five valves
- Verify the fault is at the Schrader valve rather than the service port body or hose connection
- Confirm the system is depressurised and refrigerant recovered before any work begins
