    We use primarily Lapierre bits these days and like them (good for about 2,500 taps), but have used Bolduc bits in the past and liked them a lot. Never had any Bolduc bits break. We've broken some...

    Must be spring...some things seem to repeat themselves each year.

    With rigid 5/16" tubing, we start to see failures at about 8-10 yrs. Often we'll just cut out a fitting and an inch of the tubing and put a new fitting on. The tubing itself will last a long time. ...

    So about 6 weeks. That is normal. What type of sanitation were you using for your spouts and tubing (how'd you clean them or did you use new spouts)?

    Yes, vacuum is very different in that there is less impact of tapping high or low. Different flow dynamics.

    That's a bit surprising. Municipal water can contain up to 4ppm chlorine. Tolerance specs for RO membranes are often < 0.1 ppm for short-term exposure.

    Correct. On gravity, for a 100' tall tree, you'd get ~42 psi of stem pressure at bucket height. If you tap 10' higher than that, you'll lose 10%, so will get about 38 psi of stem pressure, with a...

    Yes, sometimes considerably so. However in relation to its neighbors, a tree will retain its relative sap sugar content (SSC) rank. So a tree that is the lowest of the group will tend to be the...

    Yes, you don't want to walk away even for just a minute during any of these procedures. There is a rather fine line between syrup and black smoking char.

    Another way you can reduce the volume of sweet to store after you run out of sap (if your front/back pans are divided) is to plug or shut off the backpan, drain the backpan sweet into a bucket and...

    There is really no knowing until it's all over, but if you're on buckets you should probably wait a bit. It's the folks with a LOT of taps that are out there tapping now.

    Don't bother "chasing the sweet". There is little to be gained on a smallish pan and boiling raw sap by doing that. You'd be better off just boiling down to the lowest level you're comfortable with...

    Close to 3,000 tapped (out of 5,200). Should be nearly done by end of the week hopefully. Membranes are installed and rinsed. Several studies being prepped for the upcoming season.

    Due to their design, some liquid-ring pumps will not maintain a vacuum at less than 80% their rated speed, so if a VFD is used, it should be programmed to only operate over a narrow range. Therefore...
