What is hard water/limescale?

Water which contains dissolved chalk, lime and other minerals is known as Hard Water. This can cause major issues, if not treated, regards your plumbing, heating, water appliances such as showers, kettles, dishwashers, washing machines, toilets etc as well as limescale staining on kitchen and bathroom surfaces.

What is soft water?

Soft water is water which does not contain dissolved chalk, lime and other minerals.

How to differentiate between hard and soft water?

When a water sample is mixed with washing powder or soap, hard water produces less lather while soft water produces more later, in a shorter period.

How can I get soft water and remove limescale for good?

Soft water can be obtained by using a water softener system. Water softeners remove chalk, lime and other minerals from hard water to make it softened and this process is called ion exchange or simply known as water softening. Removing limescale is a chore! EWT Water Softener Systems bring you soft water and zero limescale.

How long does a water softener last and do I need to get it serviced?

A good water softener can provide soft water for over a decade when fed with the right amount of salt and yes you should maintain the softener with a regular annual service.

What is a Reverse Osmosis?

  • Reverse osmosis (RO) is a water purification technology that uses a partially permeable membrane to remove ions, molecules and larger particles from drinking water…. Applying an external pressure to reverse the natural flow of pure solvent, thus, is reverse osmosis.
  • It can remove up to 99. of all unwanted substances excluding bacteria such as E.coli and Coliforms for example, this will require a Ultra Violet system to be installed.
  • Water purification systems which use the reverse osmosis purification process are cheaper and energy-efficient when compared to purification units which use the water distillation process.
