How big is the RO you ordered? Likely a 250 or smaller, unless you are adding lots of taps.
I have a 250 and even when I had 1320 taps, I still had capacity to take sap (on shares) from others and process it to syrup. I have nothing hard plumbed to the sugarhouse in regards to the RO. I have 3 bulk sap storage tanks that tie together into one hose which then feeds the RO. The connection for that is a SS cam loc fitting. Each tank has a valve. Also tied to that line where I connect for the RO to draw sap, I also have 2 other lines it can draw from, the permeate tank or the concentrate tank (to recirculate). Each of those lines also has a valve. When in use I can pull sap, permeate or concentrate into the RO feed pump and all of the valves are positioned so I can close one as I open a different one, all with the RO running. On the out lines from the RO I have 1 line that sends permeate to the permeate tank and one concentrate line that sends concentrate to the head tank. The line for sending permeate to the permeate tank is connected using a potable water hose, the concentrate hose has a cam loc fitting at the RO and at the head tank.
My line from the 3 sap tanks is insulated and has a heat tape inside the insulation. That only gets plugged in if the line freezes and the heat tape thaws it in about 15-20 minutes. The only times it has frozen is overnight on real cold nights, never during a boil.
My RO is on wheels and I roll it out of my heated room to use it and back into the room after cleaning it at the end of a boil. That room has an in wall propane vented heater as well as an electric back up heater. Both are on thermostats, the propane is set at 42 F and the electric is set at 38 F. Each is more than enough to keep the room above freezing.
Personally, I do not want my RO hard plumbed to the sugarhouse, but I well understand that most larger operations are.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
