Ariston 999403 Expansion Vessel

Ariston 999403 Expansion Vessel

Expansion vessels are usually made up of two compartments, separated by a rubber sheet known as diaphragm. In a pressurised system of water and air, shifts in temperature can cause increases and decreases in pressure. The expansion vessel allows the system additional space to use when the water expands, this minimises the risk of dangerous pressure levels inside the system.
