What it is
The Dry Trap Tundish 15mm x 22mm Type AA is a backflow prevention device used on unvented hot water and heating systems. It creates a visible air gap in the discharge pipework so that water released from a temperature or pressure relief valve can be seen and cannot siphon back into the system. The unit is WRAS approved.
Signs this part needs replacing
- Water discharging continuously through the tundish
- Tundish overflowing or spilling at the outlet
- Water pooling around the tundish or adjacent pipework
- Visible scale, debris or obstruction inside the tundish body
- Gurgling or backflow noises from the discharge pipework
Before you order
- Confirm the inlet and outlet sizes match your discharge pipework (15mm x 22mm)
- Check that a Type AA tundish is the correct type for your installation
- Confirm whether WRAS approval is required for your system
- Check there is sufficient space in the discharge run to fit the tundish
