What it is

The Reflex 400 litre Potable Water Vessel is manufactured by Altecnic and forms part of the Altecnic expansion vessel range. It is a 400 litre vessel designed for potable water applications, providing the expansion capacity required within a sealed potable water system. The vessel accommodates the volume change that occurs as water is heated, helping to keep system pressure within its working range.

Signs this part needs replacing

  • System pressure rising excessively or discharging when the water is heated.
  • Water passing from the expansion relief valve or through the tundish during normal heating cycles.
  • Pressure fluctuating noticeably between cold and hot states on the system gauge.
  • Water collecting beneath the vessel or around its connection points.
  • The vessel no longer holding its pre-charge, causing rapid pressure loss on the system.

Before you order

  • Confirm the vessel capacity of 400 litres matches the requirement of the installation.
  • Check that the vessel is intended for potable water use rather than a sealed heating circuit.
  • Verify the available space and the connection arrangement at the point of installation.
  • Check the system pressure and pre-charge requirements stated in the appliance or system documentation before fitting.
