Keg Foaming

[braindead]

Little advice guys

I have 2 corny kegs connected to a maxi chiller via a python cooling system.
Getting an insane amount of foaming, I can actually hear it spluttering in the lines before it hits the taps.
Did a bit of detective work and it looks like the actual bubbles are starting from the corny keg, I see bubbles in the tube thats attached to the corny disconnect, so they must be passing all the way through and causing the splutter.
Any ideas?

Just a thought with my similar issues with lots of foaming. Check the poppets and see if anything is stuck in there causing the foaming. Such as hop debris. Just make sure to depressurize the keg before you start disconnecting the posts. Good luck and make sure to report back what you found as the cause.

Do you think completely depressurising the keg then setting it to 10 psi may work

What is your serving pressure? Or are you still trying to carbonate the beer?

10 psi at the moment

Sputtering is a classic indicator of CO2 escaping from the keg head space and being injected into the beer stream at the Out post.
The most frequent cause is a damaged or missing O-ring located under the Out dip tube flange.
Depressurise the keg, pull the Out post, remove the dip tube, see if there's an O-ring there, install one if not, or inspect the one that's there for damage (it doesn't take much, a tiny nick or a crack will do it) and replace it...

Cheers!
