I have 75 taps on 5/16 tubing running to different collection tanks this year. first year running tube and so far its working pretty good. only problem I have is my bush is flat and with 3 different collection tanks its been a lot of work getting the sap to one tank and to the shack. ive come up with a way to reduce it to one central tank for next year but would like a way to pump it automatically to the shack. I thought of running a 1/2" line from the tank up 20' and off to the shack sloping along the way (about 350') I wouldn't need a huge pump for this I would assume but I need it to be 12v because there is no way to get power out there. and is there a pump out there that I could hook a float up to to control it?
