## Summary description

Meibes FLOFIX 8/4.0 is an expansion vessel designed for domestic hot water (c.w.u.) systems, rated to 10 bar. It provides pressure compensation and thermal expansion absorption within closed hot-water circuits. Suitable for installations requiring a compact vessel for stabilizing pressure, preventing overpressure events, and protecting valves and pumps in residential and light-commercial plumbing systems.

## Long description

Meibes FLOFIX 8/4.0 is an expansion vessel designed for domestic hot water (c.w.u.) systems and rated for operation up to 10 bar. The unit is intended to absorb thermal expansion and stabilize pressure inside closed hot-water circuits, protecting valves, pumps and piping from excessive pressure variations. Its compact form factor allows installation in tight plant rooms, under sinks or within distribution cabinets where space is limited.
Advantages
The expansion vessel delivers reliable pressure compensation and reduces the frequency of pressure relief events by accepting increased volume from heated water. Constructed to work with domestic hot-water installations, it minimizes stress on system components and supports steady flow conditions. The compact design simplifies retrofits and new installations in residential and light-commercial plumbing systems.
Suitable for
 Domestic hot water (c.w.u.) systems in single-family homes and apartments
 Small multi-family or light-commercial hot-water circuits
 Installation where space is limited (under sinks, inside cabinets, compact plantrooms)
 Systems requiring protection for pumps, valves and pipelines against pressure spikes
Key specifications
 Function: expansion and pressure compensation for closed hot-water circuits
 Nominal capacity: 8 litres (usable expansion volume 4.0 litres)
 Maximum allowable working pressure: 10 bar
 Suitable medium: domestic hot water (potable water circuits where applicable)
 Form factor: compact, wall- or bracket-mountable configuration
How to use
Install the expansion vessel on the cold-water side of the hot-water circuit or at the point recommended by the installation design to effectively intercept thermal expansion. Ensure the vessel is mounted securely and connected using compatible fittings; follow local plumbing regulations and manufacturer guidance for orientation and support. Before commissioning, check the pre-charge pressure of the gas side and adjust to match the static system pressure so the vessel operates within the intended range. After installation, perform pressure and leak tests and observe system behavior during the first heat-up cycle.
Usage recommendations
Periodically inspect the vessel and connections for leaks, corrosion or mechanical damage. Verify the gas pre-charge pressure annually or during scheduled maintenance and adjust if necessary. Do not expose the vessel to freezing conditions or corrosive environments, and replace the unit if any persistent loss of pre-charge or physical damage is detected.
