Hard Water is
Hard water is water that contains calcium and magnesium. As water comes in contact with the earth’s surface minerals dissolve into it which then cause dry itchy skin, white or cream colored crusty build up on faucets, fixtures and glass shower doors. Hard water also collects inside appliances which reduces their effectiveness and life span.
The measurement for rating water hardness is a scale called grains per gallon (gpg). According to the Water Quality Association (WQA) water hardness is rated as follows.
Less than 1 Grain is Soft
1-3.5 Grains is Moderately Hard
7-10.5 is Very Hard
10.5 and Higher is Extremely Hard
A water softener removes the hard minerals from the water and therefore eliminates the problems associated with hard water.
