What it is

The Altecnic 18 litre Flow Through Potable Water Vessel is an expansion vessel of the flow through type, intended for potable water systems. It provides a contained air and water volume that absorbs the expansion of stored water as it is heated, limiting the pressure rise seen at the relief valve. It is listed by the manufacturer under Altecnic expansion vessels.

Signs this part needs replacing

  • Water discharging from the pressure relief valve as the system heats up
  • System pressure swinging or climbing beyond its normal range during heat-up
  • Water present at the air charge valve or inside the air side of the vessel
  • Corrosion, pitting or weeping at the vessel shell or its connection
  • Pressure loss on the system with no visible leak elsewhere

Before you order

  • Confirm the existing vessel is an 18 litre unit
  • Check the vessel is specified for potable water use, not heating circuit water
  • Confirm the connection arrangement and mounting position suit the installation
  • Verify the vessel is being fitted to an Altecnic expansion vessel installation
