I love the size and operation, I need to make something about this size as I do not have access to an actual hose fitting for a full size hose, I will instead need to finish the ends with barb adapters and push the water with a smaller aquarium pump.
On mine I will also gravity feed the wort through the chiller, am considering a ball valve to slow the flow if needed. My only issue at this point is going to be how to start the siphon without using my mouth. To siphon wort now I use an auto-siphon which is very nice, but I don't think that it will hold up to the heat of the wort.
My other though was to put a t on the output, and run a long tube up from the tee. By blocking the end of the pipe for a moment I could suck start the wort using a modified venturi effect, and then just uncap the end when the wort hit the bottom, keeping my mouth feet away from the wort.
Do you find that you are happy with the temperature after one pass? I am too lazy to learn the metric system, so I am only guessing that 20 is a pitching temp?
Any other ideas that don't involve 500 assorted fittings?
Great project, this is going to happen this weekend!
p.s. my condolences to the camera
