How to find micro leaks vacuum leaks in 5/16 tubbing system with high vacuum

Finding leaks in a maple tubbing vacuum system is very important to have a high sap/ syrup yield. Watch this video for some skills in finding a leak in a 5/16 line that might be tough to find.

Chad when you retapped the tree sounds hollow….yes?

[@chadsharrow9269]

No not hollow at all. Maybe just the way the camera captures the sound?

Thanks Chad. I graduated from 3/16 to 5/16 this year so it's a new ballgame finding leaks. I'm curious when you came to that one, how did you decide to remove the tap rather than give it an extra couple taps to see if that would have sealed it?

My spouts are not loose I all ready knew that. I have not had that issue in 20 years. Better technology on spout design and technique. I suppose I should have proven that in the video. Good eye!
