Hard water

The problem

Hard water leaves limescale in pipes, water heaters and appliances, wastes detergent and dries skin and hair.

Our solution

We install a water softener that exchanges calcium and magnesium for ions that do not form scale. The unit regenerates automatically with softener salt, which we can also supply.

Price

Price depends on water quality, required capacity and installation scope. We prepare an exact quote after a water analysis or site details.

Service area

We are based in Tartu County (Rehepapi põik 3, Soinaste küla, Kambja vald) and mainly serve Tartu and Harju counties – Tartu, Tallinn and the surrounding areas. We also travel to sites anywhere in Estonia.

Water with unpleasant smell or taste

Sulphur, iron or musty smells and tastes come from substances in the water that the right filter can remove.

Microbiologically contaminated water

Bacteria in drinking water are a health risk, especially in well water after flooding or when the well is in poor condition.

Salty water

Excess chlorides and sodium make water taste salty and corrode pipes – reverse osmosis solves it.

Mechanical sediment in water

Sand, clay and rust make water cloudy and clog equipment – a mechanical pre-filter solves it.

Frequently asked questions: Hard water

How does hard water show up at home?

Hard water leaves limescale in kettles, water heaters, on taps and shower glass, increases detergent consumption and can dry out skin and hair.

How is water hardness measured?

Hardness is usually measured in German degrees (°dH) or mmol/l. The exact value can be obtained from a laboratory analysis or a quick test. Hardness is one of the key parameters when choosing a water softener.

How does a water softener work?

A water softener uses ion exchange resin to exchange calcium and magnesium ions. The resin is regenerated automatically with brine, which is why the unit needs water softening salt.

How much salt does a water softener use?

Salt consumption depends on water hardness, water consumption and the unit's settings. We recommend using dedicated water softening salt (tablets) and checking the salt level in the brine tank regularly.
