Water Hardness Breakdown for Sector SO14 6
Covering 136 active delivery postcodes in the SO14 district, households and businesses in sector SO14 6 are supplied with tap water averaging 280 PPM (19.6° Clark). Distributed under the regulatory oversight of Southern Water, local tap water supplies in this catchment are rated as hard.
Registering 280 PPM, tap water across SO14 6's 136 postcodes carries significant calcium concentrations. Uninhibited hot water use accelerates limescale deposits on heating elements, potentially causing a 10% – 15% loss in boiler heat transfer efficiency over prolonged operating cycles.
Water distributed by Southern Water in this southeastern/eastern catchment is predominantly drawn from underground chalk and limestone aquifers. As rainwater filters through deep subterranean chalk strata, it naturally dissolves high concentrations of calcium bicarbonate, resulting in the consistent 280 PPM profile recorded across sector SO14 6.
In everyday household use, calcium and magnesium ions in 280 PPM water bind with soaps, producing chalky bathroom residue and scum on your morning cuppa. In sector SO14 6, washing laundry or dishware requires +35% extra laundry detergent to overcome calcium neutralization. For personal grooming, individuals with dry skin or eczema sensitivity may experience skin tightness after showers in this hard water environment.
Calibrating appliance water softening systems in SO14 6 prevents etched glassware and heating element burnouts. Based on Southern Water's official 280 PPM rating, Bosch dishwashers should be set to H04. Consult the interactive equipment guide below for custom brand settings across all 136 postcodes.
