What it is
The AAV anti suction valve is an Elson service component for the AAV assembly used on Elson wall mounted heat interface units. It is supplied under part number 24200122 and sits within the AAV arrangement on the appliance. It is a small, replaceable valve intended to be fitted as part of AAV servicing or repair.
Signs this part needs replacing
- The AAV assembly continues to discharge or pass water when it should be holding
- Water is drawn or siphoned back through the AAV instead of being held on the appliance side
- The valve fails to seat or hold against negative pressure in the AAV assembly
- Visible scale, debris or damage on the valve or its seating face
- Repeated AAV faults traced to the anti suction valve rather than the surrounding assembly
Before you order
- Confirm the appliance model and whether it is a 1 zone or 2 zone unit
- Check whether the unit is the standard or DC variant before ordering
- Verify that the fault is with the anti suction valve and not the wider AAV assembly
- Have the part number 24200122 to hand when checking against the appliance
