Water Filtration Systems 

Tap water often contains chlorine, sediment, and other impurities that affect its taste, smell, and clarity. Our drinking water filtration systems, including Kinetico reverse osmosis units, help remove unwanted elements so you can enjoy crisp, great-tasting water straight from the tap.

These Kinetico systems are specifically designed to remove chlorine, cloudiness, and a wide range of other contaminants, giving you clearer, healthier water straight from the tap. By improving both the taste and smell, these systems make every glass of water more enjoyable. Many homeowners find that with a reliable filtration system in place, they can cut back or eliminate their reliance on bottled water, saving money and reducing plastic waste. Best of all, filtered water is safer for drinking, cooking, and even your pets, offering peace of mind with every use.

Water Softeners

Hard water is a common issue in Fairfield and across Solano County. It can leave spots on glassware, dry out skin and hair, and cause scale buildup in plumbing and appliances. Our non-electric Kinetico water softeners are built for efficiency, offering soft water without the waste or hassle.

A water softener helps prevent mineral buildup in your pipes, fixtures, and appliances, which can otherwise lead to costly repairs and inefficiencies over time. By reducing hardness in your water, it also helps extend the lifespan of dishwashers, water heaters, and washing machines, allowing them to run more efficiently. You’ll notice improved soap and detergent performance, meaning cleaner dishes, softer laundry, and less product waste. Plus, softened water is gentler on your body, leaving skin and hair feeling noticeably softer and less dry after every shower.

After talking to 4 different companies, I hired AAA Water Systems to install a whole house water softener system and RO unit in the kitchen. Al explained everything in detail prior to installation and left no questions unanswered. We wound up getting a prefilter and two softener units that require no electricity and provide a constant supply of soft water to my house. When one regenerates, the other one goes on line automatically. With a single unit, whenever it regenerates it is bypassed and your feeding hard water back into the house. On installation day, Chris Rubalcaba showed up on time and got right to work. He was very meticulous in his work and in the end, we had a well designed system with a very neat and orderly piping system. He installed the RO unit under the kitchen sink and ran a line to feed the refrigerator ice maker as well. When he was done, holes were patched and jobsite was cleaned up. We decided to use Potassium Chloride instead of Sodium Chloride, but we were told that if we wanted to switch to sodium in the future, it could be done. Their system was competitively priced, and for the price we paid, I feel we got a very good system and one that will last for a long time. I highly recommend AAA as well as the system that doesn't require electricity.

We had a reverse osmosis and water softener system installed by Gerardo and I couldn’t be happier with the experience. The plumber was professional, knowledgeable, and took the time to explain how everything works and answer all of our questions. The installation was clean, efficient, and completed with great attention to detail. Everything works perfectly, and we can already notice the difference in our water quality. It’s hard to find someone who takes such pride in their work. I highly recommend their services to anyone looking for a reliable and honest plumber. Thank you for a job well done!
