"I didn't like the fact I was going to be charged a fee to have them come to my home to see what I needed. I would recoup the fee if I hired them, but if I didn't, I lost over $80. I went with a company that provided a quote based on my water analysis and did not charge me any upfront fee."

"Cindy was very nice, came to my phone, checked out my system. Later that day I received a reasonable quote for the softener, and the sediment filter. I was able to schedule an appointment for about a week later. Justin was my installer, he was very nice, professional, quick worker, and a veteran too! Justin went over the system with me and made sure I knew how to work the system."

"Scott from Priorty pump and filter is very professional and highly recommended. We contacted Scott in desperate need to get water. He returned my phone call promptly and we scheduled a service visit and he installed a pump that day. I would highly recommend Priorty pump and filter to anyone in the Whitefield, Nh area."

Water Softeners FAQs, answered by experts

Because it’s been through the water cycle, evaporating and becoming slightly acidic thanks to dissolved carbon dioxide in the atmosphere, rainwater tends to be naturally soft compared to groundwater, which has just been in contact with limestone. However, the natural hardness level of water always depends on where you are and other factors.

It depends on the type of surface. For instance, if you’re trying to get rid of hard water deposits on glass, you can spray vinegar onto the surface and wipe it off with a soft cloth or non-abrasive sponge. However, if the deposits are on granite or natural stone, it’s better to use baking soda and water rather than vinegar or other acidic cleaners.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

A water softener is a worthwhile investment if you live in an area with hard water. While hard water is safe to drink, it contains minerals like calcium and magnesium that can cause significant problems over time. These minerals build up inside pipes, reducing water flow and eventually corroding the plumbing system, which can lead to leaks and a shortened lifespan. Hard water also damages fixtures and appliances, potentially resulting in costly repairs. Additionally, it makes soaps and detergents less effective, meaning you'll use more product to get things clean. By installing a water softener, you can prevent these issues. The initial investment is often recouped through long-term savings, including lower energy bills, reduced appliance and plumbing maintenance, and spending less on soap and cleaning supplies. Other benefits include cleaner linens, dishes, and clothing, as well as softer water that is gentler on your skin and hair. In some areas, a water softener can also increase your home's value, making it a valuable long-term investment.
