We have had One Water Systems for ten years now. The quality of both the equipment and service has always been excellent. It was time to replace the 10-year system with a new system. We were extremely concerned that the water be filtered as we live adjacent to a golf course that is frequently fertilized and water subjecting us to possible run-off. Kevin at One Water acknowledged and was familiar with my concerns and assured me that the system both met my concerns regarding appropriate filtering as well as softening. We now have a new fifteen year system. AND, the price was right!
The difference in our water quality is incredible! The water tastes clean and fresh, and we've noticed a significant improvement in our skin and hair health.
Top-Notch Service: Their customer service is outstanding. They're always available to answer questions and provide support.
Kevin was very honest and respectful. He was patient and answered all our questions. 15 years of parts and labor warranty is unbeatable! Juan was very professional when he installed the system and explained how to adjust day and time of back-flush. Our water never tasted better! I highly recommend One Water Systems!
