Hard water is the result of excessive amounts of minerals such as calcium and magnesium dissolved in the water. This may represent certain problems to homes but it is not considered to be a health-related problem to humans. For water to be considered hard, the content of minerals in it should be above 7 gpg (grains per gallon)
The most common problems associated with hard water are:
- With time, pipes could become clogged
- Calcification of shower heads
- Mineral rings are deposited in toilet bowls as well as faucet tips
- Continuous washing of clothes in hard water could lead to their fiber damage and subsequent reduction of their lifespan
- Soap does not dissolve easily when bathing with hard water
Water softeners and water conditioners are usually used to remove excessive and unwanted amounts of minerals.
