"Both the salesman and the tech were fantastic. From explaining the benefits and the cost, to installing and actually making the plumbing system better, they did a fantastic job. The technician had some health issues he needed to see a doctor about, but he and the salesman returned later the same day and finished up the job perfectly. I can’t recommend them more. Oh, and our water is so much better now!"

Water Softeners questions, answered by experts

Routine maintenance involves recharging the resin bed with salt or potassium, cleaning components, and periodic inspection.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

Hard water is not considered unhealthy and is safe to drink, cook with, and bathe in. It doesn't pose a risk to your physical health and can even help you get enough essential minerals like calcium in your diet. However, it can negatively affect skin and hair. Using hard water for washing can contribute to dry skin, an itchy scalp, and may worsen conditions like eczema by altering the pH balance. Additionally, some people do not like the taste of hard water.
