What it is

The Biasi BI1801108 is a plug used on Biasi Basica COND and Rinnova Adaptive boiler ranges. It blanks off a threaded port on the appliance, sealing the opening against water or gas escape. It is a small service part, typically removed and refitted during maintenance or component replacement.

Signs this part needs replacing

  • Visible weeping or damp staining around the plug
  • Corrosion or pitting on the plug body or its seating
  • Scale deposits or water tracking at the joint face
  • The plug has been disturbed during servicing and will not seal again
  • Thread damage preventing the plug from tightening down correctly

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number on the existing plug or in the manufacturer's parts list for your appliance
  • Inspect the port and sealing face for damage before fitting a replacement
  • Have the correct sealing method to hand for refitting
