Altecnic Potable Vessel 12 Litre 3/4 Boss & Bracket PV12F

The Altecnic 12 litre potable vessel is an expansion vessel designed for use in potable water systems, absorbing the expansion of heated water and limiting pressure rise within the circuit. It forms part of the Altecnic expansion vessel range and is supplied with a 3/4 boss connection and bracket. The vessel is suited to domestic hot water and other potable water applications where a pressurised, sealed system requires a dedicated expansion volume.

• Water discharging from the pressure relief valve during heating cycles, indicating the vessel is no longer absorbing expansion.
• Persistent pressure swings between cold and hot states that cannot be corrected by recharging the system.
• Water weeping from the vessel or its connection points.
• Water appearing at the vessel's air valve when the charge is checked, indicating a failed internal diaphragm.
• The vessel will not hold its pre-charge pressure.

• Confirm the system volume and required vessel capacity against the 12 litre rating.
• Check the connection size and thread type at the mounting point to confirm the 3/4 boss will suit the installation.
• Verify that the existing vessel's mounting arrangement is compatible with the supplied bracket.
• Confirm the vessel is intended for potable water use, as required by the installation.
