@shadow745,
We have a system through Carpenter's WAter Treatment, too. They tricked us into buying another faucet, filtration system for a wet bar we hadn't yet started. We told the guy we were in process of completing our basement. We even walked him downstairs to check things our. He just said, you can return it, no problem. We finished the basement, but the permit would not allow us to install the sink like we wanted. When we called Carpenter's Water Treatment to pick up the unopened equipment they said, our 1yr warranty was past and there was nothing they could do. So, the $700 piece of equipment was now only worth $350 to them. Yea right! The salesman lied to us and also didn't tell us anything about a yearly service. We just found out this Christmas. We don't have money to pay that every year, we would have been fine without spending over $7500.
