Water Quality Comparison Analysis
Executive Summary: Sector WD4 9 vs Sector SW1A 1
Comparing tap water mineral concentration between Sector WD4 9 (Affinity Water) and Sector SW1A 1 (Thames Water) reveals a water hardness difference of 15 PPM. Sector SW1A 1 has softer water at 275 PPM (Hard) compared to Sector WD4 9 at 290 PPM (Hard).
Limescale risk and boiler heating efficiency vary based on these mineral levels. Households in Sector WD4 9 experience higher heating element degradation and kettle scale accumulation due to elevated calcium carbonate density (290 PPM vs 275 PPM).
For home appliance setup, Bosch dishwasher water softener settings should be calibrated accordingly: Sector WD4 9 requires setting H04 whereas Sector SW1A 1 recommends setting H04.
