I knew the water quality here in San Diego is of a low quality but I never expected how bad the hardness in the water can affect my appliances. Found Water Purification Systems online and decided to give them a call. They seemed very professional and knowledgeable. We scheduled an appointment for an estimate, so they could determine the exact system I would need and also test my water. Their representative showed up the next day and went over with me the the best working solution to improve my water quality. We got a very great price for a whole house water softener and a Reverse osmosis system. The installation was scheduled for the following week. It took their technician about 6 hours to do the whole installation. Very efficient and clean job.
Since them I am extremely satisfied with my water quality thanks to their system.
Great job guys. Highly recommended!
