Steve just repaired a high-tension suspension wire that holds up one of our mainlines. During sugaring, it broke and created a big sag in that vacuum line. If a sapline starts to sag, it creates a "dead zone" where sap pools rather than flowing smoothly. When sap pools in a sag, it creates temporary blockages in the line, which cause the sap to move in sudden, uneven surges rather than a steady stream. Also, during cold nights, the sap sitting in a sag can easily freeze solid, blocking the entire line and stopping sap flow until the line thaws out again. And finally, sap that pools and sits in sagging tubing during warm spells can quickly spoil, which lowers the sap's quality. So, sagging saplines reduce the efficiency of the vacuum and lower the sap yield and quality. Therefore, the lines need to be pulled tight, with no bowing or dipping of the line. To achieve this, sugarmakers hold up their mainlines with suspension wires, using steel wire-ties every 8 – 12 inches to attach them together. Steve didn’t have time during sugaring to fix this particular broken suspension wire, since it occurred in the middle of a 1,150 foot long mainline, so he fixed it now. First, he removed all the steel wire-ties from the mainline. Then he repaired the suspension wire by putting in a patch and tightened it back up. Finally, he had to wire tie it back to the mainline again. It was a long, tedious job that took him 3 days to complete, but it was necessary to do it before our next sugaring season.
