"I found this to be the perfect customer service experience! Joe was professional, friendly and informative. He quickly diagnosed my problem and immediately fixed it. Fortunatley it wasn't a big issue but rather a couple of small issues. He also carried in ten 40 bags of salt for me. He explained some features and showed me how to manually recharge the softener just in case it ever needs it. I HIGHLY recommend Water Specialties Group. this is how a service call should be done."

"Terrence Spranger was my plumber. His quote was fair. He was on time to the job. He replaced my hot water tank and shut off valve. He suggested placing a tray under the tank that has a drain hose just in case the new tank eventually leaks then it won’t run all over my basement. He had the model and serial numbers added to my receipt for insurance purposes. He was very personable and put the customer first. He went beyond what was expected of him to do. Thank you"

"I had a lot of trouble getting to the bottom of why my water suddenly was full of iron and staining everything in the house.  I am new to this dwelling and do not understand wells.  I had contacted several well inspecting companies and was unable to get anyone to come out to inspect.  Suddenly I called a reliable well company and it was recommended to me that I start by having my water softner checked and they recommended Springsoft.  I made an appointment, half expecting another bad incounter but was pleasantly surprised by the person who made the appointment but more importantly by the service man they sent.  He was the BEST! He took time with me and explained the functions and controls on the water softer very clearly.  He also inspected the softner and flushed it thru to make sure it was working properly.  He explained how to set it so it regenerated during a slow water use time (like the middle of the night) because it had been regenerating irregularly but not at a low use time.  I was very happy with the knowledge he displayed and how readily he taught me to be a knowledgeable owner of this here to for mysterious gadget.  BEST ENCOUNTER OF ITS KIND IN YEARS!!!!!!  This service man should get a raise!!!!!  Thank you for saving my sanity. "

Water Softeners FAQs, answered by experts

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

Selecting the right system depends on testing your water to understand the contaminants present and considering your household's water usage and specific needs, such as removing specific contaminants.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

Most of the U.S. has hard water, especially across portions of the West and Midwest. The areas with the hardest water include parts of Texas, Oklahoma, Kansas, Colorado, New Mexico, Utah, Wyoming, Illinois, North and South Dakota, Ohio, and New York. You’ll find soft water in parts of New England, the Southeast, the Pacific Northwest, and Hawaii.
