Water softener strongly recommended
At 30.1 °fH, the water is hard: limescale furs up water heaters and pipes and raises your energy bill. A softener typically pays for itself within 3 to 5 years.
Reverse osmosis — pure drinking water
Consdorf, like all of Luxembourg, is a nitrate vulnerable zone, and the European PFAS standard has applied since 2026. An under-sink reverse-osmosis unit removes 95–99% of nitrates, pesticides, PFAS and residues — the safest solution for the water you drink.
