What is hard water???

Hard water is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements.
The term hardness was originally applied to waters that were hard to wash in, referring to the soap wasting properties of hard water. Hardness prevents soap from lathering by causing the development of an insoluble curdy precipitate in the water; hardness typically causes the build up of hardness scale (such as seen in cooking pans). Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath. Hardness is usually expressed in grains per gallon (or ppm) as calcium carbonate equivalent.

How does a water softener work???

A water softener is a point of entry water system which is installed where the water enters the house.
The water softener contains a vessel of fine mesh IQ resin.
When the water enters the home, the resin will collect the limescale, providing you with pure limescale free water.
To ensure a continuous flow of soft water, the unit will regenerate (cleaning cycle) every 3-4 days.
The regeneration will do the following:
• Backwash: During the backwash, all the old limescale water will be sent to the waste.
• Brine: The brine tank containing salt will fill and get ready to enter the resin vessel as the brine mixture of salt and water will clean off the limescale deposits off the resin heads.
• Rinse: During the rinse cycle, the brine mixture of salt and water will be sent to waste along with the limescale that has been collected.
• Refill: the brine tank will fill to help dissolve the salt to be ready for the next regeneration.

What is the difference between a timer and a meter water softener??

The difference between a timer water softener and a meter water softener, is that the timer water softener has a timer head which regenerates (cleans itself out) every 3-4 days regardless of the amount of water used. The meter water softener has a digital display face and will only regenerate itself after a set amount of water has being used. Each cleaning cycle (regeneration cycle) will consume salt and water therefore making the meter water softener more efficient on both salt and water, as it will only go through its wash cycle when it is necessary.

Hard water effects on sensitive skin?

Hard water contains high levels of calcium and magnesium ions that bind to surfactants such as sodium lauryl sulfate (SLS) and sodium lauryl ether sulfate (SLES) – which act as detergents or wetting agents – making them insoluble, so they precipitate onto the skin.
Skin pH is normally acidic but hard water has high alkalinity which means it can raise the skin surface pH. A shift towards alkaline pH disturbs the skin’s natural function as a physical barrier and leaves it prone to colonization by potentially pathogenic bacteria which can cause infection.
A new study reveals the mechanism by which calcium and magnesium ions in hard water, surfactants, and filaggrin interact to damage the skin barrier unlocking new information about how exposure to hard water could potentially contribute to the development of eczema.
