Pure Hydration Alkaline Water Machine - High pH Water Ionizer for Home & Office - Improve Hydration & Wellness - Perfect for Drinking, Cooking & Healthy Lifestyle

When the search started for a water purification system we educated ourselves on all the types of systems available. We decided on a molecular hydrogen system. We had our home water tested and pesticides showed up in the results. These were our biggest concern along with the heavy metals. Through all our research...this system was the only one I was able to find that "actually stated" it removed pesticides, and heavy metals. We love the quality of water this system delivers. It tastes clean. About a week later, I noticed a puddle on my countertop underneath our machine. I opened it up and found a leak in a valve. I called amazon, they shot an email to the company about my issue. The same day I recieved an email from Cosan. The problem was solved that day. 3 days later, my replacement part arrived at my door. I received the best customer service possible. Prompt, professional and highly recommend this company. Thank you Cosan.Update: January 15, 2019We still love our cosan water system. The only problem we are still having is leaking issues. I have found that the plastic connectors inside the machine cannot take the water pressure of leaving the water valve open over time. This is the second identical leaking issue I have had. If I turn the valve off after every use it will not leak.
