Vaillant 089062 Connection tube

The Vaillant 089062 is a heat exchanger connection tube, supplied as a pipe spares component for Vaillant heating appliances. It forms part of the pipework that carries water into and around the heating unit, including the mains water supply route and the water pipework mounted on the wall jig. Its role is to maintain a secure, correctly routed connection between the heat exchanger and the surrounding hydraulic circuit.

• Visible weeping, staining or crusting at the tube joints or along the pipe run
• A persistent drop in system pressure that cannot be traced to any other component
• Corrosion, pitting or deformation of the tube surface
• Water tracking onto nearby electrical components or the appliance casing
• A joint that will not seal after re-making, indicating a distorted or damaged tube end

• Confirm the appliance model and GC number so the correct pipe variant is selected.
• Check the existing tube against the part number stamped or labelled on the component.
• Assess whether the associated seals, washers or O-rings need replacing at the same time, as these are separate items.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
