That is good to know it can also work with the sap going in the wash port. I like it that way because it fits perfect in the round hole of the bulk tank. Mounting it in the woods above and outside the tank is just asking it to get broken. I don't have the convenience of having it right next to the sugarhouse or any cover.

I think I will try to change out the check valves first as I think that may be the worst sorce of leaks. I only have 155 trees on this and I think I would have found a leak if there was one, but will go back again and check the mainline fittings.
