"After discovering a leak (probably in the slab) of hot water, we just decided to replace the entire plumbing piping in our 30 years old 2 story house with 3 bathrooms. The copper pipes were replaced by durable flexible plastic pipes and the project also included replacing the water heater. The crew- Manny, Mitch and Josh promised to finish the project in 3 days- and they sure did it. The GREAT TEAM, efficient and professional, worked non stop and communicated with me before taking each next step. They reconnected about 20 points (such as washing machine, dishwasher, new water heater, multiple faucets and 3 toilets) The price is a little steep but the quality of the job looks very good."

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."

FAQs for water treatment & purification system installation and replacement projects in San Francisco, CA

Water softeners consist of three main components: a mineral tank, a brine tank, and a control valve. In some smaller units, the mineral tank and brine tank are combined into one cabinet.

Professionals install whole-home systems at the point of entry of the main water line. Smaller units are installed under sinks or near a washer—these units only soften the water for that fixture, not the entire home.

  • Mineral Tank: Hard water passes into the mineral tank through resin beads, and an ion exchange occurs. Magnesium and calcium ions are exchanged for sodium or potassium ions from the brine tank.

  • Brine Tank: The brine tank contains sodium or potassium to recharge the resin.

  • Control Valve: The control valve determines when to clean the resin beads.

Choosing between a salt-based or potassium-based water softener depends on your priorities. Salt-based systems effectively remove hard-water minerals, regenerate efficiently, and are cost-effective. However, they may not be ideal for individuals on low-sodium diets. Potassium-based systems neutralize minerals without removing them and regenerate more frequently. They are more expensive but offer a healthier and more environmentally friendly option. If sodium levels are a concern and cost isn't a major factor, a potassium system may be the better choice.

To calculate your water softener's capacity, determine your grains per gallon (GPG) number by:

  • Multiplying the number of people in your home by 90. The average number of gallons used per person for washing, drinking, and cooking ranges from 80 to 100 gallons per day.

  • Multiplying that result by the hardness of your water. The average grains per gallon in the United States is 10 but can range from 0 to 17. You can find your GPG number by purchasing an at-home water testing kit.

Installing a water softener takes between two to four hours on average. The exact duration depends on the complexity of the unit and whether additional plumbing or electrical work is required. If modifications to existing pipes are necessary, installation may take longer. Preparing the installation area by clearing any obstructions can help streamline the process.

Water softeners can last up to 25 years with proper maintenance and care. The lifespan depends on the type and quality of the unit you choose. Single-tank electric water softeners may last around 12 years, while higher-quality models tend to last longer. Regular maintenance, such as routine inspections and timely replacement of salts or potassium, helps extend the life of your system. Most water softeners require minimal repairs over their lifespan.
