Default Suck back..

Any tips on cold crashing? I use a three piece airlock and it seems like im getting atleast a little bit of suckback...is there anyway to coldcrash without getting any suckback or is it pretty much unavoidable?

I used to have the same issue... Now I use an S-type airlock for cold crashing. I don't fill it up to the fill line, maybe half that... And I haven't had any problems since I started doing that.

It's worth the couple bucks to your LHBS

Try using an "S" shaped air lock. They do not allow the water to suck back.

Just use a solid stopper, The S-shaped airlocks will allow air into the fermenter, I would rather keep it sealed with a stopper/bung

+1 solid stopper for me. Learned that the hard way when I cold crashed with blowoff hose still in bucket of starsan. Ended up with a layer of starsan on top of the cold beer. I've also had suck back from both types of air locks. Solid stopper has solved it for me. My 2 cents.

Whatever you do, ditch the 3 piece airlocks. Those things are garbage.

When you eventually remove the solid stopper pressure equalizes and it sucks in a bunch of air anyways. What's the difference?

Just use an S airlock and leave it there. The exact same amount of air is going to get in whether it seeps in slowly or all at once when you eventually remove the stopper(PV=nRT). Only thing you do with a stopper is introduce the risk of fermenter collapse.

Yup.

I've also seen pictures and videos of the solid stoppers getting sucked into a carboy on occasion. I'm sure it's rare, but in the event that it does happen, good luck getting that thing out!
