Poll - Spout heaving

[minehart gap]

In the past 3 years I have used Leader CV2, Lapierre clear spouts, CDL white seasonal spouts and Zap Bak spouts. I probably should have gone with happens a lot but instead I voted happens a good bit because I don't actually know anymore. Three years ago, I kept track and it was just short of 50%, since then I automatically reseat my spouts after every hard freeze. I use a Lapierre tap handle, DeWalt drill on high speed and a new tapping bit. I have not noticed a difference between sugar maple and red maple but I have observed that the spouts in black maple stay seated.

Good luck Dr. Tim. Interesting topic.

I wonder how much of a difference 3/16" vs. 5/16" tubing play and natural vs. mechanical vacuum play.

My reply was "happens a good bit", and I would like to add that I have primarily red maples. I tap as early in the season as possible since the bud date is so early compared to sugars, and run gravity and shurflo on the 3/16. I always have to go back through and tap in a decent amount as the first couple weeks progress, otherwise vacuum is really affected.
