About a month ago I won an r/o unit in the science fair. I hooked it up as a replacement for my old one only to find out it does 50 gallons per day, which is way to slow for my needs. I't been only used once, and is in great condition. I want to sell is for $60 since it's slightly used; it's $120 brand new. Please pm me if interested I only accept cash. thanks!
