Coventry Water Hardness Report
Official mineral water quality analysis, local catchment breakdown, appliance salt calibration, and postcode outcode directory for Coventry.
Unlike its neighbour Birmingham, Coventry suffers from distinctly hard water, averaging 275 PPM. While Birmingham gets soft Welsh reservoir water, Coventry's supply relies heavily on local groundwater boreholes and treated water from the River Severn and River Avon catchments. As water seeps through sandstone and mineral beds, it gathers calcium and magnesium. Coventry residents frequently deal with furred kettle coils, scum on cups of tea, and limescale deposits on shower screens.
