Nothin' but foam!

Hi! I filled a 5 gal. corny keg. I force carbonated for 48 hrs at about 30psi. In the keg I have a Flotit 2.0. I brought the psi down to about 12 and tried serving. Nothin' but foam! I then expelled all CO2 over time to where I could open the keg. I observed that there was no foam on the beer. I closed it back up and started serving at 0psi. Obviously nothing came out and I increased slowly until I got just a small stream. The stream was all foam. I can observe that the beer line is pretty airy (as opposed to a nice solid pale yellow) so the foam is coming from inside the keg. So it's got to be somewhere between the small dip tube and the flotit. I also checked to make sure that the flotit filter could not be seen above the surface, just the float.

Also, the beer is coming out flat-ish.

Anyone have thoughts?

Ok I lied. I looked in the keg. There's maybe a 1/2" of foam in there.

Did you remember to put the small o-ring under the flange on the metal stem that replaces the oem Out dip tube?

Cheers!

30psi for 48 hours is certainly overcarbonated IF the beer was already fridge cold for that time frame. Reversing an overcarbonation state is not as simple as venting it down to zero head pressure once.

If that's not your problem, it COULD be that CO2 is getting injected into the liquid path around the diptube/post area as day_trippr is alluding to. You can test this pretty easily by carefully laying the keg down on its side so that the liquid out post is down at the 6 o'clock position. Since the beer will completely cover the area in question, it's impossible to get CO2 gas to inject itself in the stream. In other words, if it pours solid beer in that state, you have a gas leak into your liquid path under the liquid post.
