What it is

The by-pass pipe is an Ariston component (part number 998065) used in the hydraulic circuit of Ecogenus, Eurocombi and Genus MFFI combination boilers. It forms part of the boiler's by-pass arrangement, which maintains a minimum flow rate through the primary heat exchanger when system demand falls. The pipe is listed by the manufacturer under the miscellaneous category of the appliance parts breakdown.

Signs this part needs replacing

  • Visible water loss or weeping at the pipe connections
  • Corrosion, pitting or scale build-up on the pipe surface
  • Overheating or noisy operation of the primary circuit under low demand
  • Discolouration or distortion of the pipe indicating prolonged overheating
  • Evidence of previous repair or sealant around the pipe joints

Before you order

  • Confirm the exact appliance model and edition against the fitment list above
  • Check the gas variant (NG or LPG) of your appliance, as fitment differs between them
  • Verify the part number 998065 against the manufacturer's parts list for your appliance
  • Inspect the associated seals and connections, as these may also require attention
