Beer in my CO2 line

[dhelegda]

Ok this is my set up, I have 4 kegs on tap, one on reserve, when I vented the CO2 in one keg beer started coming up in another kegs CO2 line. How do I stop this?View attachment ImageUploadedByHome Brew1428782267.581305.jpg

Don't overfill your keg next time.

Adding check valves could help, but still, filling a keg to where the gas dip tube is submerged is bad juju...

Cheers!

You need check valves in your manifold.

I'll check to see I over filled. But I'm pretty sure I didn't!

Where do you get said Check valves

Super easy solution if you did overfill, pour a pint or two and enjoy.

most brew shops will have the check valves...they aren't cheap, but they are cheaper than replacing a regulator...

You can get whole manifolds with check valves for less than the price of the check valves. e.g., Ritebrew.com
But the brass manifold you have is better than those.

Do you need them? Yes and no.
I'd like to have at least one check valve between the regulator and the manifold, to protect the regulator in case of a beer backup. A long line (6') from your regulator to your manifold provides a little security buffer too.

I went with MFL fittings to be able the take the gas lines apart easily for cleaning, in case they need it. Happened 2x.

Agreed, an overfilled keg may push beer into the line if the pressure drops higher up. Otherwise it's a rare occurence.

Check valve on EVERY gas QD. Problem solved.

Even if you don't submerge the gas dip tube, you can still back suck if it's close.

These in line check valves are very cheap and work well. Much cheaper option than a new manifold or ball valves with integrated check valves.
