Water Hardness Breakdown for Sector CM2 6
Public water quality records published by Essex and Suffolk Water indicate that tap water across postcode sector CM2 6 registers an average mineral hardness of 320 PPM (mg/L of calcium carbonate). Serving approximately 300 postal units in the CM2 area, this sector falls within the official very hard water classification.
With an intense mineral load of 320 PPM (22.4° Clark), households in CM2 6 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 quality in CM2 6 is monitored continuously under the Water Supply (Water Quality) Regulations. Environmental testing ensures that the 320 PPM mineral density supplied by Essex and Suffolk Water remains compliant with all Drinking Water Inspectorate (DWI) parameters.
Household water chemistry in CM2 6 (22.4° Clark) dictates everyday cleaning efficiency. Water supplied by Essex and Suffolk 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 CM2 6 should be calibrated precisely for 320 PPM. For Bosch, Neff, and Siemens appliances, the recommended salt dosing index is H07 (Max Salt).
