What it is
The Altecnic 18 litre Potable vessel with 3/4 Boss is an expansion vessel intended for potable water installations. It absorbs the expansion of heated water within a sealed potable water system, limiting pressure rise and protecting system components. The vessel is part of the Altecnic expansion vessel range.
Signs this part needs replacing
- Pressure relief valve discharging during normal heating cycles, indicating the vessel is no longer absorbing expansion
- Water present at the air valve or schrader connection, showing a failed internal membrane
- System pressure rising rapidly when the cylinder or system heats up and dropping when it cools
- Loss of pre-charge pressure, with the vessel holding little or no air charge when checked
- Visible corrosion, pitting or weeping at the vessel body or connection
Before you order
- Confirm the required vessel volume matches the system it is serving
- Check the connection size and thread type on the existing vessel and system pipework
- Confirm the vessel is rated for potable water use, as this unit is intended for potable installations
- Check available space and mounting arrangement for the replacement vessel
