I have no problems with your service. My unit was installed promptly and efficiently. (Your people also helped me with a water pressure issue that I had at the time.) And my delivery is always on time. I never even have to give it a thought. My only wish is that you would provide paperless billing AND online payment services.
Although we still had water spots on shower faucets and slight erosion around sink drains, the water was very tasty and we never had to buy bottle water for coffee or just drinking. The service was reliable.
