What it is
The Vaillant tundish (part number 0020236850) is a visible air-break fitting used on the discharge pipework of unvented hot water cylinders. It creates a visible gap between the relief valve outlet and the drain, so any discharge from the cylinder's safety valves can be seen and safely routed away. It is listed by Vaillant for the appliance models below.
Signs this part needs replacing
- Water spilling over the top of the tundish instead of running away to the drain
- Continuous discharge visible at the tundish, indicating a relief valve passing
- Scale, sludge or debris inside the tundish body restricting flow
- Cracks, splits or loose joints in the tundish body or its connections
- Water tracking down the outside of the discharge pipe rather than through the tundish
Before you order
- Confirm your appliance model matches one of the fitments listed above
- Inspect the existing tundish and the surrounding discharge pipework for damage
- Check the part number 0020236850 against the manufacturer's parts list for your model
