Just wanted to put this little update out as I had an issue I mentioned in my first post about the Cold Crash Guardian here. I had thought that my lid didn’t have a good seal but never ran into that before so I started to really look at all my connections and noticed that on the main valve for the bag, if you open it all the way will create a pathway to the atmosphere and bypass the bag and the check valve.

You will notice the hole below, its like a 1/2 moon.

There is a simple fix and that is don’t open the valve all the way and just close it and stop when its straight out.

Other than that, once I found out these things are great and I see the bag deflate when I cold crash and happy to know that its just the CO2 from the ferment. I started to use both of my Cold Crash Guardians on both my fermentors now as common practice at my house. 8)
