What it is
This is a pipe supplied by Vokera for use in its Unica range of domestic gas boilers. It forms part of the boiler's internal pipework, carrying water between components within the appliance. The part is listed by the manufacturer under reference 20057859.
Signs this part needs replacing
- Visible water weeping, staining or crusting at the pipe or its joints
- A pressure drop on the boiler gauge that cannot be traced to any other component
- Corrosion, pitting or deformation on the pipe surface
- Damp patches or drips inside the boiler casing beneath the pipe run
- Repeated lockout or low-pressure faults linked to a loss of system water
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the pipe's position and connections in the appliance to make sure this is the correct run
- Inspect adjacent seals, washers and joints, as these are not supplied with the pipe
- Verify the part number 20057859 on the existing component or the manufacturer's parts list
