What it is

The expansion pipe is a Vokera component listed under part number 7843. It forms part of the expansion vessel arrangement on Vokera Mynute gas boilers, connecting the vessel to the heating circuit so that system pressure changes are accommodated. It is a service part intended for fitment to the appliance models listed below.

Signs this part needs replacing

  • System pressure drops repeatedly and needs frequent topping up
  • Water weeping or staining around the expansion pipe or its connections
  • Corrosion, scale or physical damage visible on the pipe
  • Pressure relief valve discharging, suggesting the expansion arrangement is not absorbing expansion
  • Pressure gauge fluctuating sharply as the boiler heats and cools

Before you order

  • Confirm the boiler model against the rating plate before ordering
  • Check the existing part number 7843 on the component or in the manufacturer's parts list
  • Inspect the pipe connections and seals for damage that may also need attention
  • Verify the appliance is a Vokera Mynute 28/96SE or Mynute 28SE
