What it is

The Ariston 340406 is a Protech anode — a sacrificial anode fitted inside an Ariston Protech hot water cylinder. Its function is to corrode preferentially to the cylinder shell, protecting the steel vessel from internal corrosion. It is designated for Protech cylinder applications.

Signs this part needs replacing

  • Heavy pitting, white or chalky deposits and material loss across the anode body
  • Discoloured or cloudy hot water with a metallic taste
  • A rotten-egg smell from the hot water outlet, indicating gassing in the cylinder
  • Corrosion or weeping around the anode connection point
  • Reduced cylinder life where the anode has been fully consumed

Before you order

  • Confirm your cylinder model and edition against the fitment list above
  • Check the cylinder's Protech designation before purchasing
  • Inspect the anode connection and thread on the cylinder to ensure it is undamaged
  • Verify the age of the existing anode, as replacement intervals depend on water conditions
