What it is

The Ariston 469004 is a sacrificial anode plug with the designation D.20.4 L:450 and a 3/4 NPT thread. It is fitted to the appliance's domestic hot water circuit, where the anode is consumed over time to protect the cylinder or store from corrosion. It is listed for use on Ariston Genus 27 BFFI appliances.

Signs this part needs replacing

  • The anode has eroded to the point where the core wire is exposed or the rod is heavily pitted.
  • The anode is significantly reduced in diameter compared with a new item.
  • Water weeping or staining around the anode plug thread.
  • The plug shows corrosion or scale build-up that prevents a clean seal.
  • The anode has reached the end of its service interval for the appliance.

Before you order

  • Confirm the appliance model and edition against the fit list above.
  • Check the thread size and anode length required for your appliance.
  • Inspect the anode port and sealing face for damage before fitting.
  • Have a suitable thread sealant or sealing washer to hand for refitting.
