What it is
The Ideal tundish is a discharge fitting used on unvented hot water systems and commercial appliances. It sits between the relief valve outlet and the final discharge pipe, giving a visible air gap where water can be seen if a valve lifts. This part is supplied by Ideal for use across its Thermstore range and Ideal Commercial appliances.
Signs this part needs replacing
- Water escaping from the tundish body or its connections during normal operation
- Scale, sludge or debris visible inside the tundish, restricting flow through the air gap
- Cracking, distortion or physical damage to the tundish body
- Discharge pipework no longer terminating with a clear, visible air gap
- Water tracking back up the discharge pipe instead of running freely to the outlet
Before you order
- Confirm your appliance model against the compatibility list, as the tundish is shared across several Thermstore sizes and Ideal Commercial units
- Check the part number stamped or printed on the existing tundish before ordering
- Note the alternative number 1783128 when cross-referencing against older documentation
- Inspect the relief valve and discharge pipework at the same time, since a tundish is often replaced alongside the valve it serves
