Andrews 80L Expansion Vessel 6 Bar 95607447

The 80L Expansion Vessel - 800L Cylinder - 6 BAR is an expansion vessel manufactured by Andrews for use with Andrews water heaters and hot water cylinders. It absorbs the expansion of heated water within an 800 litre cylinder system, limiting pressure rise and protecting the cylinder and associated components from excess stress. The vessel is rated at 6 bar and has an 80 litre capacity.

• Water weeping or dripping from the vessel or its connection points.
• Discharge from the pressure relief valve during normal heating cycles, indicating the vessel is not absorbing expansion.
• Pressure gauge readings rising sharply as the cylinder heats up.
• Corrosion, staining or physical damage to the vessel body.
• Loss of pre-charge pressure when checked at the vessel's charging point.

• Confirm the cylinder size and model against the fit list to ensure correct matching.
• Check the required pressure rating for the installation, as 6 bar and 10 bar variants exist across the 800 litre range.
• Verify the vessel capacity of 80 litres matches the specification for the system.
• Inspect the existing vessel's connections and mounting arrangement before removal.
