What it is
The Andrews anti vacuum valve 3/4 inch is a water heater component manufactured by Andrews Water Heaters. It is fitted to the Neoflo SC25 range and protects the appliance against back-siphonage by admitting air when system pressure falls. The valve has a 3/4 inch connection.
Signs this part needs replacing
- Water weeping or dripping from the valve body or its outlet
- Continuous discharge from the valve rather than a brief pass of air
- Scale or corrosion build-up around the valve seat or connection
- Evidence of water tracking down the pipework below the valve
Before you order
- Confirm the connection is 3/4 inch, as this valve is supplied in that size only
- Check the appliance model against the Neoflo SC25 units listed in the Fits section
- Verify the existing valve's part number matches 7664425 before ordering
