What it is

The Altecnic 18 litre potable vessel is an expansion vessel designed for potable water systems, absorbing the expansion of heated water and limiting pressure rise within the installation. It is supplied with a 3/4 boss connection and a mounting bracket. The vessel forms part of the Altecnic expansion vessel range.

Signs this part needs replacing

  • Water discharging from the pressure relief valve during heating cycles
  • System pressure rising rapidly when the cylinder or boiler heats up
  • Pressure dropping or fluctuating without an obvious leak elsewhere
  • The vessel feels heavy or full of water when tapped, indicating a failed internal membrane
  • Visible corrosion or water weeping at the vessel connection or shell

Before you order

  • Confirm the required vessel capacity and that 18 litres suits the system volume
  • Check the connection size matches the existing pipework (3/4 boss)
  • Verify the system pressure and charge requirements for the installation
  • Confirm there is space for the vessel and its mounting bracket
