What it is

A 22mm diameter silicone pipe manufactured by Alpha, used to carry condensate from the drain manifold to the trap. It is a flexible pipe assembly suited to the condensate path on Alpha HE appliances, where silicone withstands the mildly acidic condensate produced during combustion.

Signs this part needs replacing

  • Visible cracking, splitting or perishing of the silicone wall
  • The pipe has hardened or become brittle and no longer seals at the manifold or trap
  • Condensate weeping or dripping from the pipe or its connections
  • Water pooling inside the boiler casing beneath the condensate route
  • Discolouration or deformation of the pipe where it has been exposed to heat or condensate

Before you order

  • Confirm your appliance model against the fit list above before ordering
  • Check the pipe diameter and routing match the failed part on your boiler
  • Inspect the manifold and trap connections for damage, as these may also need attention
  • Verify the part number 1.021352 against the manufacturer's parts list for your model
