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
