Water Quality Breakdown: Sector LA23 3
According to the latest public disclosures from United Utilities, tap water across postcode sector LA23 3 (outcode LA23) registers an average mineral concentration of 45 PPM (mg/L), which translates to 3.2° Clark on the English hardness scale. This water supply is officially classified as Soft.
Good news for residents in LA23 3: with a low mineral density of just 45 PPM (3.2° Clark), water in this area is naturally soft. Limescale formation on pipework, heating coils, and shower heads is minimal, preserving boiler efficiency and extending home appliance lifespans.
To protect your dishwasher's internal ion-exchange resin in LA23 3, manual water softener calibration is required. For Bosch and Siemens dishwashers, the manufacturer-recommended salt setting for 45 PPM is H00 (No Salt Required). Since the water is soft, regeneration salt usage can be kept to a minimum.
Hard minerals interact with fatty acids in soaps, creating insoluble soap scum. In LA23 3, washing with 45 PPM water requires approximately standard detergent or shampoo to achieve a full lather compared to soft water zones. Furthermore, residents prone to sensitive skin, eczema, or dry hair may benefit from installing an inline shower filter to reduce mineral friction during washing.
