## Summary description

VAREM expansion vessel R1025228 with 25 L nominal capacity designed for installation in drinking-water systems. The vessel compensates pressure variations, protects piping and components from water hammer and thermal expansion, and maintains system pressure stability. Suitable for domestic and light commercial potable water installations where pressure buffering and corrosion-free containment are required.

## Long description

VAREM expansion vessel R1025228 with 25 L nominal capacity is designed for installation in drinking-water systems to buffer pressure changes and absorb thermal expansion. The vessel separates the water from the gas cushion and ensures stable pressure in domestic and light commercial potable water installations. Constructed for corrosion-free containment of drinking water, it helps protect piping, fittings and appliances from hydraulic shock and pressure fluctuations.
Advantages
The expansion vessel provides reliable pressure compensation and reduces wear on pumps and valves by absorbing sudden pressure increases. Its 25 litre capacity gives a balance between compact size and usable buffer volume for small to medium installations. The internal separation between the water chamber and gas cushion maintains system hygiene and prevents contamination. The vessel is suitable for systems where potable water compatibility and durability are required.
Suitable for
Domestic potable water installations
Small commercial drinking-water systems
Booster pump installations requiring pressure buffering
Systems needing protection against water hammer and thermal expansion
Key specifications
Nominal capacity: 25 litres
Function: pressure compensation and thermal expansion absorption
Application medium: potable (drinking) water
Construction: separated water and gas chambers for hygienic containment
Typical installation: vertical or wall-mounted as per manufacturer instructions
How to use
Install the expansion vessel on the pressure side of the system where it can effectively absorb pressure variations. Ensure correct orientation and secure mounting according to the manufacturer's installation guidelines. Pre-charge the gas chamber to the recommended pressure for the system, then connect to the potable water piping using appropriate fittings and isolation valves. Verify that connections are watertight and that the vessel is accessible for periodic pressure checks and maintenance.
Usage recommendations
Check the pre-charge pressure before installation and periodically during service. Match the vessel pre-charge to the system static pressure and adjust as needed. Install an isolation valve and a pressure gauge nearby to facilitate inspection and maintenance. Follow local plumbing codes and the manufacturer's instructions when integrating the vessel into potable water systems.
