Seems logical - but It's new to me and was wondering if anyone has done this.
I have one that I'm using for a cider, but I didn't use it for the primary fermentation. It holds a lot of pressure before it vents itself. It really surprised me when I lifted the little flap up.
Anyway, why not use the blowoff tube to begin with? I don't think any amount of temperature changes will cause any suckback a foot up a 1"id hose. I always start with a blowoff hose.
Your idea should work, but I think that I'd forget to switch to the blowoff tube and end up with an explosion.
