- Keith DeCarlo's Rating
Couldn't be happier! First off, the products are top of the line, excellent quality. But what really sets San Diego Pure Water apart from the competition is the customer service. From to technicians to the owners, they are all there to make sure everything is, not only working properly, but also working to the customer's expectations. I actively recommend them to others and have actually gotten compliments about how good my water tastes which is something I never expected. Thank you San Diego Pure Water! - Keith DeCarlo
- Jonathan Beck's Rating
Bob is very smart and knows alot about the science behind water and the chemicals found in them. Compared to some companies that will just try to sell you an over priced system. He actually breaks down the science of how it works, why you need specific pieces, and the history behind San Diego water. I have heard sell pitches before and used some of my own. Pure water is not a sales pitch but will actually get you what you need at a REASONABLE PRICE. - Jonathan Beck
- Lynnie D's Rating
The owner Trish is one of my heroes. She not only agreed to install a water filtration for my mothers apartment unit, but she gave us an excellent price and agreed to install it the next day to accommodate my work schedule. They didn't mind that the parking was bad in our neighborhood nor did they mind my mother does not speak English. I am very grateful for her business. Initially I had asked another water treatment company who initially agreed to do the work and told me to get the landlord authorization. - Lynnie D

- Elijah B.'s Rating
Trish, the receptionist worked to get my install date moved to the left due to my work schedule. Neil the sales rep was very knowledgeable and did not upsale me based on square footage. Martin the installer was professional and expedient. All in all the service was impeccable!! If you are in the market for a home filtration system, this company is top notched. And the system works great!! - Elijah B.

Everyone was professional and great to work with. I’ve referred them to all my friends. - Antonio Z.
