What it is

The Alpha 1.012716 is an 18mm diameter pipe that runs from the pump to the RS (sealed) chamber on Alpha CB50 LPG boilers. It forms part of the boiler's water circuit, carrying flow between the pump and the sealed chamber assembly.

Signs this part needs replacing

  • Visible weeping or water leaks at the pipe connections
  • Corrosion, pitting or discolouration on the pipe surface
  • Damp patches or staining around the pump or chamber area
  • Loss of system pressure that cannot be traced to another component
  • Scale or debris build-up restricting flow through the pipe

Before you order

  • Confirm the boiler model is the Alpha CB50 (LPG)
  • Check the existing pipe diameter and connection points match before removal
  • Isolate the boiler and drain down before starting work
  • Have the appliance GC number to hand when checking compatibility
