We were still getting great runs till the end. We averaged 41.34gpt of sap this year. Last year we did 43.1gpt with cvs and year before we were 42.58gpt. It does take longer to tap using them, but I will continue to use them. I'm certain they run longer than any other spout on the market.

How old is the tubing system? Are the trees larger than average, sometimes that can make some large yields, or just some good trees
