What it is

The Viessmann supply main, part number 7824703, is a pipework component used on Vitodens 100 and WB1A gas boilers. It forms part of the boiler's incoming supply pipework and is listed against units built from 27.04.2005 onwards. The part is supplied as a single component.

Signs this part needs replacing

  • Visible corrosion, pitting or thinning on the pipe or its connections
  • Weeping or weeping stains at the joints and unions
  • A smell of gas or a failed tightness test traced to this section of pipework
  • Distortion, kinking or mechanical damage to the pipe
  • Damage found during servicing or when adjacent components are removed

Before you order

  • Confirm the boiler model and serial number against the fit list above, as fitment is listed by serial number
  • Check the part number on the existing component before removal
  • Confirm whether any seals, washers or olives are required separately, as these are not listed here
  • Work on gas-carrying components must be carried out by a competent Gas Safe registered engineer
