Lick test! Good advice for life in general! LOL! Harbor freight has some small fountain pumps that would be perfect for this if you have 110 at your sugar shack. Just dont let it freeze. They use a small PVC impeller and should be just fine for sap.
2012 4 taps and a bunch of propane
2013 12 taps and a new home made 1x2 flat pan fit to an old wood stove, more propane
2014 40 on tube flowing down hill to a 1x2 and 3 steam pans on emergency arch. (Drowning in sap)
2015. New 2x5 flat pan and much better arch. 1x2 on new rocket stove ( this thing cranks, can't wait to use it) 60 on tubing into 250 gal tank. 6 on buckets just for comparison and a little extra!
2016. Not a good year with the mild weather winter.
