Boiler expansion vessel repair involves diagnosing and fixing issues with the vessel that regulates pressure in your heating system. Our technicians start by checking the charge pressure and inspecting the diaphragm for ruptures or tears. If the vessel is waterlogged or the diaphragm has failed, we either replace the internal bladder or install a new vessel. We also check the connection points, valves, and pipework for leaks or blockages. After repair, we recharge the vessel to the correct pressure and test the system to ensure it maintains proper pressure levels. This prevents boiler shutdowns and protects other components from stress. We handle all sizes and types of expansion vessels, from small residential units to large commercial tanks. Our work restores your system's ability to absorb thermal expansion, keeping pressure stable and your boiler running efficiently.
