The RO Buckets are great units, no doubt about it. But if you plan to get up to 200 taps, you might want to think about a 4" single-post for faster processing time. Especially if you want to process the day's sap run on the same evening, which i think generally makes a lighter syrup. An RO that can remove 65-75% of the water while producing concentrate fast enough to keep up with your evaporator is needed for this. Having this capability greatly reduced the amount of time I spent processing sap, even relative to my previous homemade RO that I had to run overnight. It is nice to be able to walk into the sugarhouse, hook up the RO to the truck tank, wait five minutes to confirm outputs are good, then light the match and start boiling 8%.
