ONYX 60L Blue Potable Vessel 1 2Bar With Feet ONYX60LPOT

The ONYX 60L blue potable vessel is an expansion vessel intended for potable water systems, where it absorbs the expansion of heated water and helps maintain stable system pressure. It has a 60 litre capacity and a blue body to denote potable water service. This version is supplied with feet for floor-standing installation.

• Water discharging from the system's pressure relief valve during heating cycles
• Pressure gauge readings that rise quickly then fall, or that fluctuate more than normal
• The vessel feels heavy or waterlogged when the air charge is checked at the valve
• Visible corrosion, weeping or staining around the vessel shell or connection
• Repeated loss of air charge shortly after the vessel has been recharged

• Confirm the 60 litre capacity suits the system volume and the manufacturer's sizing requirements
• Check the pressure figure quoted in the product name against the pre-charge and system pressure required for the installation
• Verify the connection size and thread on the existing vessel match what is being ordered
• Check the available floor space and that the feet allow the vessel to sit correctly at the intended location
