What is “Hard Water”?
Hard Water is defined as water that contains dissolved minerals (usually but not limited to calcium and magnesium bicarbonate) expressed in grains per gallon. The lower the mineral content of the water, the “softer” the water (and the more corrosive); while higher mineral content means “harder” water.How Do Water Softeners Work?
The heart of a water softener is a mineral tank. It’s filled with small polystyrene beads, also known as resin or zeolite. The beads carry a negative charge.
In normal operation, hard water moves into the mineral tank and the calcium and magnesium ions move to the beads, replacing salt ions. The salt ions go into the water.
Hard water poses no health hazard. On the other hand, the salt that remains in softened water may be a problem for those on salt- restricted diets. (Ask your doctor)
Disadvantages of a Water Softener
- Brine discharge can pollute our water.
- Uses salt chemicals.
- Reverse osmosis system often used, can breed bacteria.
- Does not remove chemicals and other contaminants.
- Warranty may not cover both parts and labor.
- Can waste thousands of gallons of water annually.
