** Important Note: All reverse osmosis systems, residential or commercial, are required to have drain water when making pure water. Our RO systems have built-in auto-shut-off valve so when the storage tank is full, the system shuts off automatically. The ratio of pure water to drain water for our RO systems are 1:3 (calculated). Average RO systems are typically 1:4, so our RO systems run more efficiently. Minimum water pressure required to operate the system is 45 PSI. Ideal pressure is 85 PSI.
