Thanks for the responses everyone! Lots to digest. I actually have a question about what seems like the simplest system, barely qualifies as a tubing system at all:
Interesting. Even 5 gallon buckets would help a lot, given that I'm only up to collect on weekends, and often my 3 gallon buckets are overrunning with sap. One question here: I'm assuming CV taps means check valve spouts, right? I ask because I've heard good things about the Zap Bac spouts (
