High Magnesium & Calcium Creates Hard Water
High levels of dissolved calcium and magnesium makes cleaning clothes more difficult. Additionally, it can make cleaning your hair and skin well a challenge. It can also create streaking on dishes and glasses, scaling on faucets and shower heads. The scale produced can damage your home’s piping distribution system as well as damage your water-using appliances. Hot water heaters have been known to fail way before their useful life due to scale build-up on the temperature sensor. This coats the sensor, creating insulation from the actual water temperature. This in turn causes the system to work harder to bring the temperature up to what “it thinks” it should be. Fortunately, there are high efficiency filtration solutions that will remove these minerals through the proven ion exchange softening process.

Scale Formation
Symptoms such as bad odors & taste, staining of laundry, bathroom fixtures, etc. are indicators of problems. However, the preferred starting point is to get a test to identify minerals or contaminants and at what quantities they exist. This will lead to an effective system recommendation..
A softener is a type of whole house filtration system that is designed for removing hardness minerals (magnesium & calcium) as well as dissolved iron and manganese. High efficiency softeners that are more efficient with both water and salt usage are preferred. They are installed at the water’s point of entry into your home or business.

BAD ODORS & TASTE 
In addition to water softeners, there are many other types of systems to remove bad tastes & odors, sediment and other objectionable minerals and contaminants. A test and analysis will lead to the best approach. For more information on bad odors & taste, see the link at http://bad-odor-taste/.
