PLUMBING INSTALLATION DIAGRAM
Zip recommend expansion vessels to be installed in line with the current HSE
guidelines. Expansion vessels should be installed, in cool areas on cold flowing pipes,
mounted as close to the incoming water supply to the water heater as possible, mounted
vertically on pipework to minimise any trapping of debris and to minimise the volume retained
within them, with an isolation and drain valve to aid flushing and sampling and designed to
stimulate flow within the vessel.
