What it is
The Vaillant 0020236861 is a pressure relief valve supplied in the 1 1/2 inch version. It is fitted to Vaillant unvented hot water cylinders and opens to discharge water when system pressure exceeds the valve's set limit, protecting the cylinder and associated pipework. It forms part of the cylinder's safety group arrangement.
Signs this part needs replacing
- Water continually weeping or dripping from the discharge pipe with no rise in system pressure
- The valve fails to reseat after operating, leaving a permanent drip
- System pressure will not hold and drops repeatedly without an obvious leak elsewhere
- Visible scale, corrosion or debris around the valve seat or outlet
- Discharge occurs at pressures below the normal operating threshold
Before you order
- Confirm your cylinder model against the fitment list above
- Check that the existing valve is the 1 1/2 inch version before ordering
- Verify the part number 0020236861 against the manufacturer's parts list for your appliance
- Confirm the connection arrangement on your installation matches the valve being replaced
