We are selling two Springtech 600 GPH RO machines. These machines have nothing wrong with them, just looking to upgrade. One machine has been used for 5 years but had a new membrane installed so only 3 seasons on it. The other machine has been used for 3 seasons. Both machines have been well maintained and do not pass any sugar. We are only selling them to upgrade to a larger machine. We are selling both machines for $14,000 or, $8,000 a piece if sold separate. Contact us if you have any questions. Cell: 740-403-0648
