Limescale Removal

Waterteck specialises in water softener systems for limescale removal and hard water correction

What is hard water?

Hard water is water that contains more minerals than ordinary water, particularly calcium and magnesium.

Hardness (or lime) is the combination of calcium and magnesium carbonates, and sometimes high levels of metals can add into the total hardness in water, usually is reported as mg/l of Calcium Carbonate.

The following is a hardness guide:

  • 0 - 75 mg/l is considered to be soft water
  • 75 - 150 mg/l is moderately soft water
  • 150 - 300 mg/l is hard water
  • 300 mg/l or greater is considered to be very hard water

Negative effects of hard water:

  • Limescale deposit in pipes
  • Energy cost of water systems increased 15-20 %
  • Skin problems
  • Efficiency of boilers, washing machines, and dishwashers reduced
  • Reduced life span of solar heating systems and air conditioning units
  • Reduced life span of all domestic appliances like kettles, irons etc.
  • Soap and detergent waste

What is a Water Softener?

Water softeners are an Ion Exchange system based on chemistry, it exchanges ions of calcium and magnesium (hard water) for sodium ions.  It is the most efficient way of removing limescale from the water supply. Softeners can operate automatic, semi-automatic or manual.

A good water softener will last many years; they need little maintenance filling them with salt occasionally.

The cost of water softeners greatly depends upon the type of water softener installed, the energy that is used, the hardness of the water and the water usage.

Benefits of Water Softening

  • Washing machine and dishwasher last longer
  • Cleaning-supply costs are reduced
  • Water flow and pressure are improved
  • Water heater efficiency is increased
  • Shower, tub and sink cleaning is easier.
  • Reduction of phosphate contamination in the environment
