I woke up yesterday morning to my wife telling me that I had some beer to clean up in the garage. Kinda shot me out of bed like a cannon. I run out to the garage and there’s beer all over the floor and dripping out of my fridge. The damn cobra tap didnt seal after I pulled a pint the night before!!! I lost about 3.5 - 4 gallons of beer overnight to the floor and eventually, a mop. It turned out to be a really good beer. Glad I still have a gallon or so to drink! I’m making the jump to faucets mounted in the door and getting rid of the cobra taps this weekend! What a way to learn!
What, you never heard of straws? 
I have done this before. :-\ All you can do is clean it up…
Up to 4 gal of good beer on the floor? Alcohol abuse!
Dang. This is one reason I never leave the CO2 on. The loss is limited to the pressure in the keg.
It’s such a shame to mop up good beer.
Funny, I’ve never spilled any crappy beer. I have left the cobra tap too close to the door on the fridge and when closed it turned the tap on. Mess is more contained now that the fridge is a freezer. And I’m constantly putting a cobra on a new keg with the tap in the open position, which is how they are stored for drying after cleaning.
Sorry for your loss.
Uh, IMHO it will not stop flowing until the beer goes flat. May slow it down, but won’t stop it.
