Matt, It was a very nice trip around your shack and learned a lot, now it is to put it all in to a plan. I was thinking of placing a tank in front of the vac, one that could hold some pressure and use the auto shutoff on the cleaner to stop the flow of vac. sounds primitive but seems like a plan that may work. All this would be closely watched.
Brandon, I have read all the post about a natural vac on smaller lines and will test it this coming season. More sap than we got this past year would be welcomed greatly. 7gallons on 75 taps is not a good average even for buckets, but all is greatly accepted in to our home.
We also have to consider upgrading our pans and arch. Many things to consider and little time to make them happen.
