I am a mild enthusiast who is a small operation. My brother-in-law, grandfather and I have less then 20 taps out and only produce a couple gallons a year. We have been looking into RO systems but don't need the large $1500+ setups. We are interested if anyone could help us in what to buy and how to assemble a small system that will satisfy our needs. We typically will boil anywhere for 40-70 gallons of sap at a time currently. If anyone could offer some insight and knowledge we appreciate it.
