What it is

The expansion vessel tube is a Vaillant component used to connect the expansion vessel to the hydraulic circuit within the appliance. It is supplied under Vaillant part number 0010029319 and is fitted across a range of EcoTec combi and system boilers. Its role is to carry water between the vessel and the boiler's internal pipework as system pressure changes.

Signs this part needs replacing

  • Water weeping or dripping from the tube or its connections
  • Visible cracking, splitting or perishing of the tube material
  • Kinking or deformation restricting flow between the vessel and the circuit
  • Corrosion or scale build-up at the connection points
  • Repeated pressure loss from the heating system with no other obvious cause
