If I run water up the tubing- instead of filling the tank from the top - it only takes a few gallons to get flow - as the entire length of tubing is full to start with.
It's only when the line is dry when starting.
As far as digging up the line - not practical.
The line runs inside a PCV tubing - and it's held in the center of that PVC by neoprene insulation. The whole system - tank and tubing - is insulated.

Maple sap spoils when it gets above 45 degrees. We pick up the sap early in the morning - frequently with ice in the collection barrels. There is a thermometer in the tank - and I frequently see temps down to 29f - without freezing - due to sugar content.
