Glowworm S801859 Expansion Vessel

Glowworm S801859 Expansion Vessel

Expansion vessels generally consist of two inner sections, split by a rubber sheet known as diaphragm. In a pressurised system of water and air, fluctuations in temperature can cause the pressure within the system to increase. The expansion vessel allows the system additional space that can be used when the water expands, reducing the risk of unsafe pressure levels inside the system.
