Turning off Vacuum

[doocat]

Just curious as to how many people turn off vacuum after freeze at night as opposed to leave it on for the season once tapped.

Pros and cons??

I will turn it off if the 5/16" lines are frozen solid. The extractor may be frozen up but if you go out into the woods the lines may still have liquid and I don't want it pulled into the tree.

I dont stick outond to see when everything is frozen I just fill up the gas and let it run into the night. Then the next morning up early and get it going. If the sun is up things are thawing.

If the sap isn't running and the lines are freezing up, I shut the vac off. No need to pay the power bill if there is no sap. But we leave it on as long as there is anything coming in to leave as little as possible in the lines to freeze.

I'm setting a guy up with a refrigeration control unit. It makes at 37deg and breaks at 27 deg. Idea is 37 above freezing sap should be running and after everything freezes up at night hopefully vac pulled lines clear it shuts down. Will fing out how well it works

Flat I dont think it will pull the lines clear. They will freeze up even with vac on them. But I run my pump till after freeze up then pull the plug. Would be nice If I could keep it on all season but dang weather wont let me.

We turn off one the water stops running. Not going to pay for the pump to run with no water comming in. Our wet/dry system runs under gravity too so it will drain any water in the lines out even with the pump off.

If it starts to freeze too much it will make a snowball in the top of the releasor and block the inlet lines, it sucks the ice droplets out of the line untill that point though.
