Water Hardness Breakdown for Sector PE13 2
Public water quality records published by Anglian Water indicate that tap water across postcode sector PE13 2 registers an average mineral hardness of 310 PPM (mg/L of calcium carbonate). Serving approximately 243 postal units in the PE13 area, this sector falls within the official very hard water classification.
With an intense mineral load of 310 PPM (21.7° Clark), households in PE13 2 face rapid limescale deposition. Dissolved calcium and magnesium leave thick chalky residue on shower screens, aerators, and heating elements while reducing central heating boiler efficiency by up to 18% – 25%+.
Water distributed by Anglian 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 310 PPM profile recorded across sector PE13 2.
Household water chemistry in PE13 2 (21.7° Clark) dictates everyday cleaning efficiency. Water supplied by Anglian Water at this level necessitates +50% extra detergent alongside dedicated limescale inhibitors, while inline shower head filters can help sensitive skin by mitigating mineral residue during washing.
To preserve internal ion-exchange resin chambers, domestic dishwashers operating in sector PE13 2 should be calibrated precisely for 310 PPM. For Bosch, Neff, and Siemens appliances, the recommended salt dosing index is H07 (Max Salt).
