    Good to hear that everything below has gaskets!
    Your going to wish you built one sooner after you boil concentrated sap! I bought a used one back in '11, after years of not wanting one and thinking I didn't need one.
    I can tell you now my mindset back then was simply foolish.
    Good luck with it and enjoy it!

    Thanks for the kind words everyone. I'm glad its going to help people out. I have had multiple private messages already from people wanting my parts list.
    Good news is, I record/document everything (engineery brain), so below is my parts list with rough pricing and links. i also have reference links below some items.
    The parts are essentially in an order based on the flow of the schematic, aside from the dolly build on top.


    Enjoy!



    Shopping list:


    Dolly frame: $35
    http://www.harborfreight.com/700-lb-...uck-62900.html

    Extra steel: $60
    72" 1.5 x 3/16" thick flat stock
    10' 1"x1"x1/8 square tube
    12ga aluminum plate (needed to polish myself, but the welding shop had the aluminum and used a hydraulic shear to cut it perfectly for me)


    Parts in order of flow:


    Shallow well 1hp pump: $140
    maybe look elsewhere as this is cast iron.. it may rust if its not filled with glycol in the off season. only time will tell...

    Not only did you do a beautiful build, very clean and neat, but your parts list is equally neatly arranged. Nice job. You will REALLY enjoy making syrup now.

    I just bought the exact temperature controller off eBay. With the same little probe. I'm going to try getting a compression fitting similar to the ones that come with the pt100 probes from auber and screw it into a tee on the low pressure side of the RO.
    Did you find a different probe or did you use the one that came with the temp controller?

    Update:

    Good news if you bought the same Inkbird temp controller thats on my RO. Just buy the proper 1/4" or 1/8" compression fitting for their included generic submersible probe and put in a tee as bricklayer stated, and you're good to go. the Inkbird needs a thermistor probe with the proper ohm range made for that box.

    i already bought an exhaust gas probe with compression fitting for the Inkbird box but found out it wasnt compatible. Luckily the probe portion is 5mm too so i just swapped the compression fitting out and all is good. Good idea bricklayer!

    below is the incompatible probe i bought, but used the compression pieces:

    Were you able to incorporate the temp controller for a high temp shut down? I put my controller on heat mode and ran the main power for my control relays through the temp controller. In heat mode the temp controller relay is NC so power travels through. If high temp is reached the relay opens and system shuts down. My control system with 2 contractors and 4 coil relays only draws 3 amps max 120v and temp controller is rated for 10 amp 120v. Reason I ran main power through it is because when running a long wash cycle and not around it cuts all power to RO when done. Just like shutting it off.

    I havent looked into high temp shutdown. Is it something that happens often? What components are in danger if high temps are hit? I know the membrane should be kept an eye on. I just planned on being around to monitor when i do the 10-20min wash cycles.

    Since I've built my RO I've been reading and learning about how to use/ wash it properly. I have an old membrane I've been playing around with also so I've got a feel for how the RO will operate. One thing I have read almost everywhere is that you get the best cleaning of the membranes when the wash temp can be brought to the max wash temp of the membrane. In my case since I have a multi stage pump the pump actually heats up the wash water slightly while circulating it. A ran a complete wash cycle on my old membrane before Christmas. I brought the water up to 105 F with a drop in pail heater. Dumped it into the wash tank. Cycled it through untill my high temp shut off kicked RO off at 113.5 My MES membrane say the are rated for 113 F so that's what temp I set it toTook about 40 minutes I think. Might of been longer. I was doing other stuff while it was washing. Good practice for maple season.

    Mine shuts off on high temp every day when I do a wash cycle after concentrating.

    Fair enough. Ill connect the NC side of the temp controller to the main on/off power switch on my electrical box. That way the whole box will shut down when its hit.
