What this means at home

Hard water isn't dangerous. It's just demanding.

Hardness measures the calcium and magnesium in water. At 34°fH, Mondercange is above the comfort threshold (12°fH) — limescale builds up and shows in daily life.

Appliances

Limescale builds up in the water heater, washing machine and dishwasher, shortening their lifespan.

Fixtures

White deposits on taps, shower heads and glass — endless cleaning.

Soap & laundry

Soap lathers poorly, laundry comes out rougher, you need more product.

Taste & feel

Limescale shows in coffee, on skin and hair after showering.

Your water every day

Understand limescale at household level.

Select your home type and household size to explore the annual estimates associated with your local water hardness.

Your annual estimate

Potential limescale removed and estimated savings.

The calculation changes with local hardness and the selected household size. It uses a reference consumption of 135 litres per person per day.

Frequently asked questions — water in Mondercange

Is the tap water in Mondercange drinkable?

Consult your municipality’s current analysis report for your supply zone or locality. Water hardness describes limescale and is not sufficient to establish the water’s compliance with health requirements.

Is the 34°fH value exact for my tap?

It's the official network value for your zone. The hardness at your tap may vary slightly depending on network blending and your building's plumbing.
