frozen pump line
I am looking for suggestions. I have an electric releaser that pumps sap 500 feet or so to a tank in a truck. My problem is when everything freezes up there is still sap in that line which freezes solid. Then the trees start running before that line thaws out and the releaser cant pump the sap then fills up into vac line. I put a fitting on an air tank and I blow the line out when it is going to freeze early,which seems to work ok. problem is when it freezes overnight. Any ideas how to keep line from freezing up on me? or how to thaw out quickly? I am stumped
