building first RO
I am building my first RO using a 4x40 canister. I have done a ton of reading and can't find anywhere as to what needle valves people are using to restrict flow.
here is what I have
goulds j5s shallow water pump
5 micron filter
marathon 3/4 motor
procon series 4, 330gph
i have searched hi and low for a more detailed parts list for my self with no luck. any help to finish this would be greatly appreciated. Always willing to listen and learn.
Thank you
I used these and on the concentrate line i use the built in neddle valve.

you might be under powered on the 330 procon with a 3/4 hp motor.

My results are my evap rate is 15 gph. i can set the ro to run just a little bit faster then this and with a by-pass loop will turn 1% sap into 6% . i have a 13 gallon feed pan that preheats the concentrate before running into my syrup pan.

I' tried a 330 procon with a 1 Hp motor. Had to switch to a 1.5hp. Only could run around 150 psi with the 1 Hp which worked fine for me at the time with two membranes in series, but if you want to make high concentrate I would recommend at least a 1.5 Hp motor. As for needle valves I've had good luck with just a basic brass needle valve from the hardware store.

Also, I am only running one membrane right now. Thought we would get this mastered before adding more. That was the reason with the series 4 330gph pump. Appreciate all the help so far
For the 330 you will need a 1.5 hp and will be set for future expansion.

If you want bigger than 3/4 Hp you gotta go 56c bolt on with love joy couple instead of the clamp on
So I am using the 3/4 motor right now but will upgrade it soon to a 1.5hp. My next question is tubing and hoses. What does everyone use? I was thinking I could just use pex but A, it is too stiff to work with easily and B, it is only rated for 160psi. I believe I want to run around 200psi coming out of the HP pump and through the membrane house through discharge.
