What it is
The Vaillant 0020127214 is a pressure relief valve used on Vaillant geoTHERM VWL air-to-water heat pump units. It opens to discharge water when system pressure rises above the valve's set point, protecting the appliance and its pipework from over-pressurisation. It is listed by the manufacturer for the VWL 45/1, 65/1 and 75/1 A 230V models.
Signs this part needs replacing
- Water continually weeping or running from the valve discharge pipe when the system is at normal pressure
- System pressure repeatedly dropping and needing topping up
- The valve failing to reseat after it has lifted, leaving a persistent drip
- Scale, sludge or debris holding the valve seat open
- Visible corrosion, cracking or deformation around the valve body or outlet
Before you order
- Confirm the appliance model on the data plate matches one of the VWL 45/1, 65/1 or 75/1 A 230V units listed above
- Check the existing valve against the part number 0020127214 before ordering
- Inspect the discharge pipework for blockages, as a restricted outlet can cause the valve to weep
- Isolate and depressurise the appliance before removal and fitting
