What it is

The Altecnic 8 litre Flow Through Potable Water Vessel is a diaphragm expansion vessel designed for potable water systems. It forms part of the Altecnic expansion vessel range and uses a flow through configuration to suit installations where water is intended to pass through the vessel. Its role is to absorb the expansion of water as it heats, helping to keep system pressure stable.

Signs this part needs replacing

  • The pressure relief valve discharges water during heating cycles
  • System pressure rises too high or fluctuates more than expected
  • Water is visible at the vessel connection or the vessel body shows corrosion
  • The vessel feels waterlogged or heavy when tapped, indicating loss of air charge

Before you order

  • Confirm that 8 litres is the correct capacity for the system and the vessel being replaced
  • Check that the flow through connections match the existing pipework
  • Verify that the vessel is suitable for the potable water side of the installation
  • Allow enough space for the vessel and its connections to be fitted and serviced
