GrainFather G30 - Active Fermentation

[rycardo]

Hello Everyone,
I own a GrainFather Canonical Fermenter Pro, during my fermentation process I noticed the Rubber Bung is lifting and some Co2 is going out through the space between Rubber Bung and the fermenter.
Do anyone had this issue? How to fix?
I’m using some weight to keep the Rubber Bung on place.

Thanks

I don't have that same fermenter, but it's not a unique problem. Short term, all you can really do is shove it back down/weight it down.

A longer term fix, if you still want to use an airlock, would be to use a triclamp fitting that connects to a short piece of tubing that takes the airlock in the other end of the tubing. Something like this:

Of course, you'd need to get the appropriate size for your fermenter.

Or better yet, build/buy a spunding valve.

Another solution for the TC fitting.

1.5" Tri Clover Connection Blow Off Tube. NorCal Brewing Solutions

Much easier than trying to find a 10mm tube to stick in there.
