If the system pressure is high, the water flowing through it has greater momentum. When this flow is abruptly stopped, often due to the closure of lever-operated taps or valves such as those in dishwashers and washing machines, it creates a shock effect that causes the pipes to shudder and vibrate.

This stainless steel expansion vessel can be used as a water hammer arrester for individual outlets, such as taps or washing machines, or for small groups of outlets, such as in a bathroom. It eliminates the annoying knocking sound and prevents potential damage that might occur from moving pipes splitting or cracking due to prolonged vibration.

The expansion vessel shock arrester should be installed close to taps or valves to minimize the shock effect on the system.
