We had a system installed by David. I was amazed by their service, pricing and all around business. I have priced water systems from other companies in the past and found the people I spoke with to be nothing more than salesman who did not really care about the customer and their concerns. David cares about his customers and it shows in his actions as well as his words. I would recommended this service to anyone! Oh yeah, now I can drink the water in my house and don't have to keep buying bottles from the store!
