Improving your water in Weiswampach
Compliant tap water doesn't mean ideal water. Two complementary levers: treat limescale (comfort, appliance lifespan) and purify drinking water (nitrates, pesticides, PFAS).
Soft water — softener optional
At 14.5 °fH, the water in Weiswampach is soft: a softener isn't essential. It's still useful for maximum comfort (skin, laundry) or to protect a sensitive installation. If in doubt, ask for advice.
Reverse osmosis — pure drinking water
Weiswampach, 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.
