I have a small operation currently, and next year might have 25 taps total. Is there a rule of thumb for # of RO membranes and size vs the number of taps? Meaning...should I use 2x 100gpd, or 3x 100gpd, or 2x 150gpd?

2021: 28 taps. 18"x36" flat pan and dual natural gas burners.
2020: 31 taps. 3 full size steam table pans on a custom 6x water heater natural gas burner setup.
2019: 31 taps on silvers. Back porch gas cook top with 2 full size steam table pans. An amazing 14.9 gallons in my backyard!
2018: 22 taps on 9 silvers. Propane turkey fryer and full size steam table pan on electric stove. I made 4.25 gallons in my backyard!
Hodorskib, I built mine with 3-400’s as well, but used 1/4” line. Is yours built with 3/8”? Do you think I will loose much flow by this? I thought I would start with this and upgrade the line if needed.
Thanks,
Jason

Are you running sap or just water to test?

Thanks. I will run it this way and see how it does. Probably a couple weeks before I get to use it yet.

Three membranes with a 400gpd booster or smaller will not need more than 1/4" hose. If you start getting to 60 or 70 f the membranes might pass enough permeate to require a 3/8 inlet. I tested it with both and there was no noticeable difference in flow/inlet pressures at 40f.
once I've rinsed out my new membranes, then what? I can just let em sit for a few days til I get sap again?

That is normal with just water. Once you put sap through it the pressure will build.

A huge thank you to hodorskib for posting the info. I built the RO according to the plans and I was able to take sap from 70- 1 ratio to an 11-1. Running 1.25% sap at 115 psi took me to 7.5%. 20180224_140114.jpg
Give them a quick rinse (5-10 min) every other day until your sap start flowing. Then give a good rinse - 30 minutes before you put sap through it.

Great thread - appreciate everything. I’m jumping in on the RO bandwagon this year! With that, can any of you offer me some advice on the height placement of the pump? I’m reading some say it should be below the sap and watching videos where it is above the sap. In your opinions does it matter? Thanks for any advice you can offer.
