Water Quality Comparison Analysis
Executive Summary: Sector PO12 3 vs Sector SW1A 1
Comparing tap water mineral concentration between Sector PO12 3 (Portsmouth Water) and Sector SW1A 1 (Thames Water) reveals a water hardness difference of 25 PPM. Sector PO12 3 has softer water at 250 PPM (Hard) compared to Sector SW1A 1 at 275 PPM (Hard).
Limescale risk and boiler heating efficiency vary based on these mineral levels. Households in Sector SW1A 1 experience higher heating element degradation and kettle scale accumulation due to elevated calcium carbonate density (275 PPM vs 250 PPM).
For home appliance setup, Bosch dishwasher water softener settings should be calibrated accordingly: Sector PO12 3 requires setting H04 whereas Sector SW1A 1 recommends setting H04.
