I recently kegged my first beer and my keg system was working well for about a week or so, then foam. lots and lots of foam. I initially force carbed at about 25psi for 36-40 hours. It poured perfect pints every time. I had a little trouble getting the line pressure down to 10 psi with my dual body regulator, so it was a bit higher, closer to 13-15 which is not ideal. I assumed that the foam was due to excessive keg pressure built up over time, so I released the pressure. The problem is, I released too much.... and am now having a hard time getting the pressure back up. My regulator pressure gauges are showing zeros on both keg lines with tank and lines open. A bit perplexing since the tank pressure looks ok. anyone have any insight?
 
If you released all the pressure in the keg, the CO2 is going to come out of solution to try and fill that head space - it needs to achieve equilibrium between the pressure in solution and pressure pushing down on the beer to keep it in. To fix this, all you need to do is hook the keg up to the gas and fill the head space. Just set your regulator to about 10psi and wait. The foaming should eventually decrease as CO2 gets pushed back into solution. You may not want to serve at 10psi though, depending on how long your hoses are. Also, make sure you a) don't have any leaks/gaskets missing from connections. And b) don't have any warm spots in the line. If your beer is coming out cold and hits a warm spot in the line, it will foam up.

Hope this helps...
 
The dual regulators tell you the pressure of the keg. First close the valve that goes from the regulator to the keg. If the pressure spikes back up to 10 then you know it should be fine up to that point. Open the valve that goes to your tank. If it drops to 0, slowly start to increase pressure until it goes up to 10. If you turn your regulator to max pressure and it remains at 0, listen to hear if gas is entering the keg. If it is, that could mean you have a leak and pressure is not building up. Check all of your connectors, your relief valve, and the gas line going from the regulator to your keg.
