What it is
This is a check valve for an automatic air vent, manufactured by Altecnic and listed within the Altecnic air separation range. It fits between the vent body and the system connection, allowing air to be released while preventing system water from passing back through the vent. The valve has 3/8 x 1/2 connections.
Signs this part needs replacing
- Water weeping or dripping from the automatic air vent when the system is running
- The vent continuing to discharge water rather than seating closed
- Loss of system pressure that traces back to the vent assembly
- Visible scale, corrosion or debris at the valve seat preventing it from sealing
Before you order
- Confirm the vent assembly is an Altecnic unit from the air separation range
- Check the existing connection threads measure 3/8 and 1/2 before ordering
- Inspect the vent body and seat for damage, as a worn seat can mimic a failed check valve
- Isolate and drain the relevant section of the system before removal
