Water very commonly contains hardness elements such as magnesium and calcium, dissolved rock, hence the description of hard water. Soft water is when these minerals are removed through a process known as ion exchange. All of these are symptoms of the need for softened water. The average cost of a water softener is around $3000 for a base model, but some of the larger models the companies offer can cost as much as $8,000 or more. Your tech should test the water and measure the size of your home, check on the number of faucets you have and find out how many people there are in your household. If you have a larger than a normal house or have more contaminants, you’ll need a larger water softener. The key to good health is consuming and using clean water. Drinking as well as using clean water for our daily activities such as bathing or washing is extremely important for our health and wellbeing. As water comprises nearly 60% of adult body weight, it is essential for homeostasis and metabolism in all organ systems. Chronic exposure to low dose contaminants and toxicants in water may pose a health hazard and has been associated with neurological impairments.
