Anyone doing a primary to secondary transfer like this?

    I found, maybe in another thread here, this article about a closed-loop transfer system. Looks cool, got my curiosity piqued, and just happened to stumble upon a similar diagram on Better Bottles website. Hard to get a direct link through that page so www.better-bottle.com, then click on the "Product Information" tab at the top, then using their menu "How-to Tips", then Racking -> Carboy>Carboy. Scroll down to either "Oxygen Free" or "External Purge Gas". I'll use External Purge Gas.

    I got one of these BB with the racking adapter and flow valve yesterday, got it assembled and filled it up and let it sit overnight to test the seals. I have 2 of their reusable top closure bungs and a dry tap airlock coming by Saturday. Looks like I'll need a couple of extra pieces to make this all hook up nice and work.

    The only part I'm not sure of - "Run the equivalent of about 4 carboy volumes of purge gas through the output carboy and pressure balancing tubing.". How much is 4 carboy volumes of purge gas?

    I use CO2 to transfer, but not nearly as involved as that process.

    just purge the receiving vessel with CO2, usually a keg. then use a special cap (its orange with two holes and fits over a carboy, have not seen one in a long time) apply pressure, dump the first bits of trub and done.
    just need to be careful not to over pressure the carboy. it works very well.

    a bottling bucket with spigot can work with gravity too.
    Cheers.

    I do it similarly, to purge and transfer to a secondary carboy (and then later, from secondary to keg). It's simple, it works, and I haven't lost or ruined a batch in 35 years of doing it this way.

    I do this as well. Used to purge the keg and then pop the lid and drop the tubing into the bottom and fill from there. Just recently started pushing it through a liquid out post to the bottom of the keg through the dip tube, just make sure to vent the keg since the 40psi in the keg will shoot straight up through the line into the Better Bottle which is no bueno.

    40psi? Why so high? What is your procedure? For purging I thought of hooking up to the gas line as usual, then vent out through the liquid out line, but I don't know what PSIs to use or for how long.

    I use the higher PSI to purge the keg, seat the lid, and blast any O2 out of my dry hops. Usually I would do like 20 psi (which would still back flow) but my lids weren't seating right with the dental floss so I lubed up my o-rings and cranked the PSI up.

    Yep. That's one lesson I learned the hard way.

    My carboy cap popped off, loud bang, Better Bottle jumped 3+ inches off the shelf in my fridge. Only took me once to learn that lesson. Just glad the cap popped off and not the fermentor exploding.
