"Rick advised me via text message what to do to get the system up for a soft restart right away. Then he came to my home, tested my water, and made all the necessary adjustments to make sure the system was working properly. I didnâ t buy the original system from Rick and now I wish I had. I high recommend him!"

"Not good. The water leaks had caused black mold that had to be repaired. When repairs were completed 3 months later, the valves still leaked from the stem when turned on. It was past 60 days so I had to pay another $100 service fee to have the water leaks fixed. He tightened the packing and quoted $350 to replace the valves. Sheesh."

"Originally I contracted with him because we had a lot of water in my basement.  The water was pretty high.  I had a few people off of Angie’s List come look at it and they were giving me estimates between $20,000 to $25,000.  The guy who came in from Concrete Raising gave me some good advice.  He told me not to start with an expensive solution.  He told me to try the sump pump first and see if it would work.  It seems to have solved the issue and it only cost me $4000.00."

Water Softeners FAQs, answered by experts

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.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

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.

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.

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.
