"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"John has always been about the most polite and professional contractor we have used, and has been our go-to guy for several years now. From installing a water softener to fixing old piping to/from the upstairs bath to installing a toilet (which I couldn't do since I've never sweated copper piping, which this required). Prices are fair, and the jobs are not done until he's sure they are. Will definitely continue using his services. Highly recommended."

Water Softeners FAQs, answered by experts

A good hardness level for drinking water can vary based on personal preferences, but an ideal level is 3.5 to 7 GPG. This means your water isn’t soft or hard. However, some people prefer the “fresh” taste from the minerals in hard water, while others like the smoother, “slippery” texture of soft water.

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits 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 tools like Angi’s state licensing tool to verify an installer's license status.

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.

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