Get matched with top water treatment pros in Oak Park, CA

"Advanced Water has been servicing my old soft water unit and RO for the last 10 years; coming to replace filters, test the water, etc. I called them immediately when the soft water system gave out and they came right out. Tim Douds did a great job explaining all of my options to replace and pricing. A couple of days later, Tim came back and did a great job installing their new system. I highly recommend this company for all your water treatment needs."

"Great experience. Prompt, and did outstanding work on the installation. Best price for the type of system. I would definitely recommend."

"Giovanni was very professional, arrived on time, and kept in contact by phone and message about arrivals, needed equipment, and expected work. He was careful to explain what needed to be done and why and approached work with a positive attitude. The job involved replacing some valves on an exterior faucet set on copper pipes. Afterward, he noticed that the house water pressure was high and found that the regulator was not working so I had him replace that. Overall this was a very positive experience and I would say he is one of the good guys. Give him a call if you need some plumbing work done."

"Fair and and reliable. These guys are awesome. Aaron installed me a clean out in the front of my house. 5 stars!!!"

"Joshua and his team came out and gave me what I needed an outstanding water filtration in a location where I personally wanted. I knew our family needed some kind of water treatment and after researching other companies and prices PureLux was a better product. What made even better they worked with as to where I wanted it installed."
