I will admit to you all that I am fairly new to the trade, having taken over a pub only a few months ago now, but I have worked in pubs for a fair time.
Today I changed my Guinness Keg as usual and did exactly the same as I do every time.
Just in case – here are my steps
Go to cellar and see cellar bouy is empty and so is keg
Turn gas off
Uncouple old Keg
Recouple new Keg
Turn Gas on
“Bleed” Cellar bouy (or whatever you call it!)
Make sure the ball is at the top and not blocking the line
Therefore gas is on – cellar bouy is full up with Guinness and the ball is at the top of the bouy.
When I went back to dispense it worked for so long then started frothing until it stopped. Back to the cellar and the Cellar Bouy was empty again!
I checked the gas and I still have at least 1/2 tank of 70/30, so I did the whole uncoupling and recoupling again, redid the cellar bouy and tried again.
I noticed that one of my other gases was on the borderline (C02) so I changed that because I know that when I line clean my Kegs all my gases have to be ok for the whole system to work.
But Every time I tried to dispense the Guinness the cellar bouy emptied again! I had to give up and say that the Guinness was off!
I can also see that there is a lot of air gaps in the lines from the Keg to the Bouy
Has anyone any idea what has happened – Gas seems ok and the keg is coupled correctly. — Could there be a problem with the Keg?
Thanks for all your help
