What it is

The Alpha 1.023582 is an 8 mm diameter pipe for the expansion vessel on Alpha CD-series LPG boilers. It forms part of the expansion vessel connection within the appliance. This pipe is listed for the Alpha CD12S, CD20S and CD28S LPG models.

Signs this part needs replacing

  • Water traces, weeping or staining around the expansion vessel pipe or its joints
  • Corrosion, pitting or scale visible on the pipe
  • Kinks, cracks or deformation in the pipe
  • Leak at the expansion vessel connection when the system is under pressure

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the pipe diameter and routing on your appliance before ordering
  • Confirm whether the leak is from the pipe, its connections or the expansion vessel itself
  • Have the boiler isolated and depressurised before fitting
