2 Keg System, 1 Foaming, 1 Not

[Beer_Me14]

I'm new to kegging and installed a two keg system with a taprite regulator and an air distributor for two faucets with 5ft of line each at 3/16 ID.

I initially kegged an IPA, put 12 psi on it and left it for 5 days. It poured perfect. I had multiple beers off it with no problems. However, when I kegged my second beer (lager) and put it CO2 on it (waited 5 days), the first beer starting foaming like crazy while the new beer pours perfect.

Need some help on what caused this and what I can do to get my first beer pouring perfect again. I just bled the CO2 off the foaming keg and put it back on. I'll see how it looks in the morning. Thoughts?

5 days is likely not long enough to reach full carbonation. So my first thought is that your lines are too short, and when your beers reach full carbonation they foam. Venting the keg then putting it back on the same pressure I don't expect will do anything. Many folks including me need 10+ ft lines at typical carbing pressures to avoid foaming.

I agree with the comment above. At least 10 feet beers line to balance out your system. You can find a co2 volumes chart online that will tell you temperature and co2 psi to reach the right amount of co2 per your taste or beer style. On my system, I set my co2 regulator to 30 psi to set the lid on my corny kegs then burp of the co2 a few times to purge any oxygen out. Then I set my desired carbing pressure and leave it. Most of my beers are drinkable after a week but are just right at about two weeks.

The other beer is pouring perfect though and its been two weeks with the same length of hose and same psi all off the same regulator. It was only a foaming issue once I hooked up the second keg to the distributor.

fwiw, it takes a solid two weeks to get a full corny close to a good carb level here using constant pressure, three weeks to be perfect.

Therefore I agree with the afore stated premised, that the original keg was barely half-carbed when it was pouring ok, but with the passage of time it carbed up to where the short lines became an issue. Nothing to do with the second keg, never mind a distributor...

Cheers!

To make ya' feel better, unhook the second keg, and see if the problem disappears.........

Adding the second keg unbalanced the system. Once everything is equalized it might settle down.

FYI, I have 5' 3/16" lines and have perfect pours. 12 psi at 38 degrees my tubing is thin walled so I suspect that is why.
