Water chemistry can fluctuate across supply zones in DN20. The lowest mineral concentration is recorded in sector DN20 0 at 310 PPM, whereas sector DN20 9 experiences higher mineral levels reaching 310 PPM.
Due to the very hard water (310 PPM) in DN20, limescale build-up can occur on heating elements, shower heads, and boilers. Setting your dishwasher water softener to the correct level (e.g. Bosch setting H07 (Max Salt)) is strongly recommended to prevent cloudy glassware and internal scale accumulation.
