"I knew nothing about water filtration systems before hiring Eco Water. I had serious issues with my water and got filtration system and bacteria light for whole home. It was only a one day instalI but could have been less if it was not for running lines from one side of house to the other for the system to be put in my garage. The system works great!! I would recommend Eco Water for your home."

"Stephen was great, my tub backed up with water and my toilet would not flush, turns out my septic field needed replacing. Very responsive, reasonably priced and best of all. I didn’t have to leave my home during the repairs. I’d give 10 stars if I could."

"I had a water heater emergency on a Saturday, and my four girls were frantic with no hot water.  I called several plumbers who were not able to come out on the weekend or wanted way too much money.  When I called Steve at All about Plumbing, he was very nice and was able to come out the sameday.  He did not charge an estimate fee, gave me an estimate to fix the problem.  He installed a new heater that night and we were back in business and ready for Sunday morning showers before church.  He promised to be there at a certain time and was.  He was professional.  I would recommend to my friends and family."

"Had water damage to hardwood Floor, used Angies List to locate floor contractor, had 3 quotes. Mike Flaker seemed to be the most knowledgable and his price was fair. Work quality was excellent, he did a great job matching stain to the existing floor. Highly recommend him for any of your floor needs!"

"The guys with Tri State were excellent. They not only installed our water filter, they also corrected some plumbing issues at our new home no charge. They seemed to really enjoy the science behind plumbing and so they knew exactly what they were doing. Communication was excellent and they were very friendly guys. I would recommend them."

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.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.

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.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.
