Expansion Vessels / Pressure Vessels
Expansion and pressure vessels play a massively important role in keeping water systems safe, efficient, and reliable. They manage pressure fluctuations, protect boilers, pipes, and pumps, and help maintain smooth, consistent water flow.
Whether you’re looking after domestic hot water or larger commercial systems, the right vessel keeps your setup running without leaks, bursts, or unnecessary wear. On this page, you’ll find options for potable water expansion vessels designed to keep drinking water safe, as well as pressure vessels built for general system protection and performance.
