Well I have a Lapierre 24 x 60 set up and my big tank of ice has thawed. This is a new evaporator and basically my first kick at it. I have used a friends of mine before and it was a Dominion Grimm 18 x 60. My question is what is the average height (amount) of sap in the front and rear pans. My unit has a float adjustment for the front pan and rear so starting to boil in the morning and thought I would ask. I had that information somewhere before but lost it. Jack
