Back in the 1980's a small team of water professionals got together in Northern California with one goal in mind; to improve lives through better water. The target was not only to help families, but businesses alike! By 1993, we came to realize that there was only one manufacturer that would allow us to achieve this goal while also exceeding our customers' extraordinary expectations. This WAS, IS and ALWAYS will be Kinetico Water Systems. Today AAA Water Systems, Inc. is able to exclusively offer Kinetico; the world's best product line of non-electric water purification, filtration and softening systems. Now with over 40 years of water treatment expertise, we are a strong group of over 40 team members operating across the greater Northern California area.

"The water here in Manteca is terrible. It smells, tastes disgusting and leaves your skin dry and ashy. I research water softeners/purifiers online and with my neighbors and then contacted AAA Water Systems since they use the Kinetico water systems. I had an appointment with Damian Fernandez and he was very thorough in his explanations of the system, how it works, maintanence, future costs, just everything I needed to know to make an informed decision. And it was the best decision ! I know have purified water right at my sink from the reverse osmosis sytem and soft smell free water from all the taps. No more hard water deposits, no ashy skin and coarse hair. No more bottled water to drink or cook with. The installers were wonderful...prompt and professional. Everything spotless when they were done. They carefully explained and showed me how to use, maintain, and just in case, shut the system off. They also provide little measuring scoops for the proper amount of soap to use in the washing machine and the dishwasher."

Water softener services FAQs

The license requirements for water softener installation depend on your location. Some municipalities require that the installer hold a plumbing license, some require a permit and an inspection, but no license for the installer, and some require a permit and a license for the installer. Regardless of the local laws in your area, it’s always a good idea to hire a licensed plumber or installer. These pros will install your system properly and have the experience to size the system appropriately. Use Angi’s state licensing tool to check your installer’s license status.

The cost to install a water softener system is $1,500 on average, ranging between $200 and $6,000. The labor for water softener work typically costs between $150 and $1,000, so you can add that to your equipment costs to get an accurate total. Your price will depend on many factors, including the following:

  • System capacity 

  • Home size

  • Water hardness levels

  • Type of water softener

  • Presence of electricity in the installation area

  • Local permit costs

Water softeners are worth the money if you live in an area with hard water. Hard water is safe to drink, but it poses serious threats to your plumbing system. The minerals in hard water will gradually build up on the inside walls of your pipes, reducing water flow to your fixtures. The minerals can also gradually corrode your plumbing system, reduce its lifespan, and increase the risk of leaks. Hard water also makes soap and detergent less effective. Water softener systems can solve all these issues, making them a great investment.

It’s possible to install a water softener yourself, but we don’t recommend it. Water softeners require working with copper pipes and electrical wiring, neither are suitable tasks for most DIYers. Plus, working with water and electricity together is dangerous and could pose a risk to your safety. Water softeners also need to be calibrated so that they don’t make your water too soft, as soft water poses just as many risks as hard water. Overall, it’s well worth hiring a local water softener installer to place your water softener system.

Your water softener size is based on your total household water consumption. In most cases, you can assume the average household member will use around 75 gallons per day. Multiply that by the number of people in your home, then multiply by 10 (for the typical grains per gallon). You’ll get a number in grains that should help roughly size your water softener. However, it’s best to hire a professional to install your system and use more exact numbers, like your exact average water consumption per day and starting water hardness.
