"Their people and services are EXCELLENT ! On 12/08, Adam and another person came to my home and did estimate, measured the water hardness, answered all our questions. And then we signed the contract. They didn't push you at all to buy additional or fancy stuff which you may not really need. On 12/11, they sent a plumber to install the equipment (called us before coming) and it took him about 2 hrs to finish. Everything looked good. However, around 6pm, we found it leaked a little bit at one joint (not severe, dripping very slowly) so we called them. We thought they may fix it the second day or even later. However, they sent out another plumber immediately to my home to check/repair. He cut off the leaking part and installed a new pipe, also replaced a joint he thought it was not done perfectly. He came in at ~8pm and left at ~9:30pm. We had very pleasant conversation, by the way :) The system has been working beautifully since then. Their people are very polite and professional. Their services are excellent. We highly recommend this company !"

"The sales rep took several water testsâ ¦ The sales rep took several water tests and showed me the results. She told me that I needed more than just a water softener. I also needed a system to address the rust and iron in my well water. I did not want to spend a fortune but the sales lady was pretty convincing. The price was good and the workmanship was excellent. My water is clean again ! Now I can tackle the original problem. My toilet has bad rust stains. I will either get it clean, or replace it. I could not do this until the water was fixed."

"Raphael was great to work with. We lost all water pressure and thought the water softener was the likely culprit. He explained repair and replacement solutions for a water softener that had gone bad and showed me why the unit had failed. He ensured all fixtures could work on a temporary bypass solution and cleaned up the areas affected, which was all throughout the house, and was professional. I appreciated that he took the time to explain something I didn’t know much about. We will be in touch to purchase a new unit from the company. I would highly recommend Raphael and Fenwick Plumbing!"

Water Softeners FAQs, answered by experts

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.

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.

Hard water isn’t necessarily bad for you. In some ways, it’s good for you. If you’re deficient in magnesium or calcium, hard water can give you a mineral boost that you wouldn’t get with soft water. However, this is where the benefits of hard water pretty much stop. Hard water can cause many minor inconveniences and lead to costly, premature replacements of your water-using appliances.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

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.
