What it is

The Vaillant anode 0020107793 is a sacrificial anode for Vaillant hot water cylinders in the Vantage and Unistor families. It is fitted inside the cylinder to protect the steel vessel from corrosion by sacrificing itself. The part carries a G1 x 26 x 517 size designation.

Signs this part needs replacing

  • The anode has been in service for several years and is due for inspection or renewal.
  • The anode rod is heavily corroded, pitted or significantly reduced in section.
  • Rust-coloured or discoloured hot water from the cylinder.
  • Corrosion or staining around the cylinder connections.
  • The cylinder is showing signs of internal corrosion despite normal operation.

Before you order

  • Check the cylinder data plate and confirm the exact model against the fit list.
  • Confirm the existing anode's thread and dimensions match the G1 x 26 x 517 designation.
  • Isolate the cylinder, drain it down and depressurise before removing the old anode.
  • Check access to the anode boss and confirm the cylinder is suitable for anode replacement.
