Cimm - 2 Litre Potable Expansion Vessel - ACS2 510242/001

The Cimm 2-Litre Potable Expansion Vessel is a compact, commercial-grade pressure vessel designed for domestic hot and cold sanitary water circuits, water pressurising systems, and small-scale heating or cooling loops. Commonly utilised as a water hammer arrestor or small expansion buffer, its primary function is to absorb sudden pressure spikes and thermal expansion within tight plumbing layouts. This targeted protection prevents safety valves from weeping and minimises physical strain on pipework joints, taps, and domestic appliances.
