"When I needed to get a water heater replaced before a weekend after calling it on a Wednesday afternoon, they did it. Every other plumber called could barely send someone to give a quote! It can be hard to find a service company in San Francisco that behaves like they want your business so I was truly grateful. And while the job cost a lot more than I expected, they were able to help with the price because I was in a tight spot financially. Also, when I had an issue that I discovered later on with hot water not getting to the hydronic central heating, Adam came back to bleed the line when I was out of town! That's excellent customer service right there! They have a great team and they run a tight ship!"

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."

"I had another plumber come out and said he'd need to remove the entire bathtub and refused to look at it further. Andre came out and knew exactly what to do; he was courteous, punctual and most of all he got me going for an extremely reasonable price in about an hour. I've been draining my tub with a bucket for three weeks; now I can finally take a shower again (I guess you can say this was on my bucket list!). I can't praise Andre and Quality Plumbing highly enough! He's got a big thumbs up from me :-)!"

"They recommended a good solution for the occasional shallow flooding in the garage (installing a sump pump) They started soon after we submitted the request and they did a good job. Most importantly, the pump kept the garage dry through our seemingly endless rains this winter. There are 2 reasons I rate the job with 4 stars rather than 5. (1) The job did not pass the city’s inspection and a critical connection had to be reconfigured (after which it passed) and (2) there was some weirdness around payment on the last day of the actual work (before the inspection) in which the crew seemed unwilling to leave without a check and then were slowly driving around the neighborhood afterwards. When I brought this up with my contact at the company, he denied that the van was theirs (which it definitely was) and didn’t really explain or defuse the bad feeling this created. But … they did a good job and in this day and age that’s really important and can’t be taken for granted. I recommend this company with the suggestion that paperwork, permitting, terms of payment etc should be clearly settled in advance."

Water treatment & purification system installations and replacements FAQs
In a reverse osmosis system, water from your main line—or from a designated faucet—is pushed through a semipermeable membrane under pressure. The membrane’s microscopic pores trap dissolved solids, heavy metals, and other contaminants, while clean water passes into a storage tank or straight to the tap. The leftover concentrated water simply drains away. The result is clear, great‑tasting water delivered right where you need it.
A plumber can set up a point‑of‑use unit in one to two hours. A whole‑house system is more involved and often takes one to two days because it ties into the main supply line and may need extra plumbing. During installation, the pro mounts the unit, connects the pipes, checks for leaks, and tests performance so you’re ready to pour a glass as soon as they leave.
Reverse osmosis removes dissolved solids, heavy metals, and many microorganisms, giving you water that tastes cleaner and protects your family. Softer water also helps appliances, faucets, and ice makers last longer. Because you’re filling reusable bottles instead of buying single‑use plastic, most homeowners save money and cut waste. In short, you get better‑tasting water, longer‑lasting appliances, and a smaller environmental footprint from one straightforward system.
