## Summary description

VAREM expansion tank model R1008228 with 8 L capacity, designed for potable (drinking) water systems. The diaphragm-type vessel provides pressure buffering and compensates thermal expansion in domestic and commercial water installations. Suitable for connection to hot or cold water circuits to reduce pump cycling, maintain stable pressure and protect plumbing components.

## Long description

VAREM expansion tank R1008228 with an 8 L capacity is a diaphragm-type vessel designed for potable water systems. It provides pressure buffering and absorbs thermal expansion in domestic and light commercial hot and cold water installations. The tank separates the water from an internal air cushion by a flexible diaphragm, helping to stabilise system pressure, reduce pump cycling and protect valves, fittings and pipes from pressure surges.
Advantages
The compact 8 L volume and diaphragm design ensure consistent pressure control without waterlogging. The air-water separation prevents corrosion of the internal shell and maintains reliable performance over time. Because it is intended for potable water use, materials and construction meet requirements for use in drinking water systems, allowing direct integration with hot or cold circuits. The tank’s simple installation profile minimises space requirements and maintenance interventions.
Suitable for
Domestic cold and hot potable water systems
Small commercial water installations and service loops
Pressure boost and circulation systems to reduce pump on/off cycling
Systems requiring compensation for thermal expansion
Key specifications
Type: Diaphragm expansion tank for potable water
Nominal capacity: 8 litres
Function: Pressure buffering and thermal expansion compensation
Connection: Standard plumbing connection for domestic water circuits
Suitable media: Drinking water (hot and cold)
How to use
Install the expansion tank on the pressure side of the system according to local plumbing practice and the system manufacturer’s instructions. Ensure the tank is mounted in a stable position and connected with appropriate fittings and isolation valves to allow service and replacement. Adjust the precharge pressure of the air side to match the static system pressure before filling the circuit; this helps to ensure correct diaphragm operation and to avoid premature cycling of the pump. Verify that all connections are watertight and that the system is vented of air after filling.
Usage recommendations
Periodically check the tank’s precharge pressure and inspect for leaks or signs of loss of diaphragm function. For systems with variable operating pressures, set the precharge slightly below the minimum system pressure and follow manufacturer guidance for maintenance intervals. Replace the tank if the diaphragm shows irreversible failure or if you notice frequent pump cycling that cannot be resolved by pressure adjustment.
