"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."

"Secondwind Water Systems was excellent from start to finish. The process began about three months ago with Jesse, a Certified Water Specialist, who thoroughly tested our water and designed a comprehensive system. He was patient, informative, and never pushy while I took time to decide. Installation was completed this past Monday and included sediment filtration, a water softener, radon and PFAS removal, and reverse osmosis to our drinking water and refrigerator ice maker. Patrick, the senior technician, and his assistant Ronald were professional, knowledgeable, and did a very clean, well-organized basement install. Patrick took the time to explain how the system works and what maintenance is required. Christine in the office was friendly and extremely helpful with payment and organizing all documentation needed for state reimbursement related to the PFAS system. Highly recommend Secondwind Water Systems for quality work and excellent customer service."

"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

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.
