Potterton Tundish 5139811

The TUNDISH is a Potterton Commercial spare part, supplied under manufacturer part number 5139811. It forms part of the discharge pipework arrangement on Potterton Commercial IHE boiler installations, providing a visible air gap between the safety discharge and the drainage point. Its role is to make discharge from a safety device visible and to break the direct connection to the drain.

• Water escaping from around the tundish body rather than passing cleanly through it
• Visible cracking, distortion or a loose or missing air gap section
• Scale, sludge or debris restricting flow through the tundish
• Evidence of overflow or backing-up at the tundish during discharge testing
• Weeping joints where the pipework connects to the tundish

• Confirm the appliance model against the fit list above before ordering
• Check the existing tundish and surrounding pipework for the cause of any leak or restriction, not just the tundish itself
• Verify the manufacturer part number 5139811 matches the part being removed
• Check the discharge pipework route and termination are clear before fitting
