I have three separate runs on 5/16 line each with thirteen taps running to seperate 55 gallon drums.. Each line has a drop from ten to fifteen ft. in a 120 ft. My question is: barely if any sap is coming out by the barrel but if I pull the last tap it seems to run backwards uphill? Why would that be? Any suggestions would be great. Thanks
