Leicester Water Hardness Report
Official mineral water quality analysis, local catchment breakdown, appliance salt calibration, and postcode outcode directory for Leicester.
Leicester tap water falls firmly into the hard water category, with an average hardness rating of 245 PPM. Sourced by Severn Trent from regional surface reservoirs (like Cropston and Thornton) and blended with River Dove and Derwent transfers, the water dissolves significant mineral content from the local Triassic mudstones and limestones. Leicester homeowners must regularly descale kettles, clear white crust from tap aerators, and ensure combi boilers are protected with heating inhibitors.

Practical calibrations for kitchen appliances, heating systems, and personal care tailored specifically to Leicester's water profile.
Monthly descaling required. Boil one tablespoon of citric acid to dissolve crust before it flakes into morning cuppas.
Level 4 or 5 (High). Essential to maintain ion-exchange resin bed and prevent cloudy glass etching.
High scale hazard. Up to 10%–14% fuel efficiency loss without scale protection. In-line scale reducer and BS 7593 inhibitor essential.
Hard minerals bind to fatty acids, forming soap curd that strips natural moisture and irritates dry or eczema-prone skin.
