I’m curious if anyone else has tried this or knows why I shouldn’t try it. I’m planning to use a 4048 Shurflo pump next year to provide suction for Around 110 taps on 3/16” tubing. I plan to use a temperature sensor and controller from e Outstanding to turn the pump on at 32 degrees and off at 30. A 12 volt deep cycle battery will power everything and be charged by a 100watt solar panel.

My thought is that the pump will turn on when it warms up and turn off after it freezes and the sap has stopped, so that the pump and filter will be empty when the pump shuts off. I think that will prevent burst lines? I may add a Power to open solenoid valve to allow sap to flow into my tank if the pump fails.

I know there are more complicated ways to do this but like to keep things simple when possible. Anyone else using something like this? Thanks.
