"We purchased water treatment systems and Reverse Osmosis systems for two homes from The Water Doctor from San Antonio. They offered a fair price, extra benefits for my military service and a superior installation. Their after sale service was a major factor in our decision. Their responsiveness when a minor installation issue came up was outstanding. We highly recommend The Water Doctor."

"It was a pleasure to work with Justine from Prostar Water Inc. She was on time and provided a competitive quote. She was patient in explaining the different options I have. Definitely would highly recommend her."

"Fantastic. Justin and his dad contacted me immediately and coordinated the whole process. They got parts within a day and installed around my family's schedule. They quoted an extremely fair price and did the whole job for that price including removal of the old system and full install and verified operation. Great family business!"

"I had a great experience with the team who first came out and identified the reason I had no hot water to the replacement of the water softener which was the problem. I decided to replace the water heater as well because of its age."

"Always prompt, courteous, and efficient. Very knowledgeable on Rainsoft water conditioning and softener systems."
