I am curious what folks do with warm weather and vacuum systems.

I typically keep my vacuum on for short warm-ups, say 1-3 days, as I can keep pulling sap. The sugar and quality drop, but I keep the sap moving so taps stay 'fresh'.
We are in the midst of a 5 day stretch with no freezing. On Day 1 I pulled about 3000 gallons of sap from 2300 trees in 9 hours, but that night it just quit. The sap went from 300 gph to less than 30 gph.
With no freeze showing for 5 days, I did something I am not sure about. I shut off the vacuum.

My thought was take the time to clean things up and fix some things, and the day before the next freeze, drain lines, clean tanks and releasers and see what the freeze brings. I am hoping for a second half of the season.
What do others do in this situation?
