Brighton & Hove Water Hardness Report
Official mineral water quality analysis, local catchment breakdown, appliance salt calibration, and postcode outcode directory for Brighton & Hove.
Brighton and Hove tap water is naturally very hard, averaging 285 PPM. Sourced directly from deep boreholes in the South Downs chalk block, Southern Water pumps water that has spent months filtering through calcium carbonate rock. While this gives Brighton water a clean, crisp mineral taste, it wreaks havoc on household appliances. Kettles fur quickly, shower glass clouds with etched scale, and hot water cylinders accumulate substantial limescale sludge over time.
