Altecnic Potable Vessel 25 Litre 3/4 Boss & Bracket PV25F

The Altecnic 25 litre Potable vessel with 3/4 Boss & Bkt is a potable water expansion vessel used within Altecnic expansion vessel installations. It provides a pressurised air cushion that absorbs the expansion of heated water in unvented and potable water systems, limiting pressure rise across the circuit. The vessel is supplied with a 3/4 boss connection and a bracket.

• Water discharging from the pressure relief valve during heating cycles, indicating the vessel can no longer absorb expansion.
• Pressure gauge readings rising sharply as the system heats up, then falling again once it cools.
• Water coming from the air valve or Schrader valve when the charge is checked.
• A waterlogged vessel body that feels heavy and gives little or no air response when the charge pressure is tested.
• Repeated loss of air charge shortly after re-pressurising the vessel.

• Confirm the system is a potable water application, as this vessel is intended for potable use.
• Check the required vessel capacity of the installation matches 25 litre.
• Verify the connection size and thread of the existing vessel match the 3/4 boss fitting.
• Confirm that the bracket arrangement is suitable for the intended mounting position.
