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 repair or service projects in Mendota, CA

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
