I just got my kegging setup, and just lost two tanks worth of gas! Three things in my case: one of the kegs has a bum gas poppet and is leaking; one of the gas connections (regulator to keg line) needed to be tightened a lot; and three, I didn't really understand that you need pressure to seal the keg lid BEFORE you lock it down. Hopefully I got everything this time....

I put a brand new 4 way manifold into my keezer when I built it and lost about half of a 20lb tank over night. I did the soapy water trick and found that I had a bad relief valve. I replaced the relief valve with a plug and then found out that all of the brass connections on my manifold were leaking. I had to take it apart, re-tape it and tighten it all back up.

Wow, two pretty bad cases of bad luck...

I did get a new manifold recently. I inspected it before going to use it for the first time. Didn't see any Teflon tape on the threaded connections, so I took it apart and added the tape. I also decided to modify it so that I could use a standard gas QD to connect it to a second manifold. I made SURE all the threaded fittings were in nice and tight before going to use it. It's been working like a champ from day one after that. I also altered another (two port) manifold so that I could use the same gas QD connection to go to the other one. Really like that option. Oh, and I put a gas post on the inlet side of the 3 port, so I don't need to do anything different to connect one of my CO2 regulators to it. I'm thinking about getting another manifold (3 or 4 port) and doing the same thing with it. It really helps since I'm carbonating kegs in the basement. This way I can have pretty much ALL my spare kegs on CO2 carbonating (at least partially) while the brew fridge is full.

Use a spray bottle with water and dish soap in it. With the co2 turned on, spray all connections with it. If there is a leak you will see bubbles form. Where there is bubbles there is a leak.

Also, for giggles, check the liquid posts after you've charged your system. Make SURE you don't see any beer weeping from them. If you do, depressurize the keg and inspect the o-ring on the dip tube. If it looks worn (at all) change it. Very few things are worse than going to pull a pint of a really nice brew only to get air (or nothing since the CO2 tank is empty again). It gets worse when you open the brew fridge/keezer to find all the beer inside it.

I tested mine with soapy water before I lost it all. The leak in the relief valve didn't bubble because of the way it was built. I only saw it when I removed the manifold from the wall of the keezer. When I found it, I replaced the valve with a plug and turned on the gas again. That's when I found the other leaks. Apparently the relief valve was leaking bad enough that there wasn't enough pressure to see the other leaks. After I got it all taped and tightened up it's been good.

I guess sometimes you can do things "right" and still have things go wrong

So many things to do! Thanks for all the help.

Once I full up I'll be sure to let everyone know what worked.

Appreciate it

None of my manifolds have relief valves. I have those on the kegs. I got the manifolds in my brew fridge (and almost my entire CO2 system) from Keg Connection. Great people there, who really help out their customers either to figure out what to get, or how to trouble shoot if something's going sideways and you can't figure out why. Plus, they can special order things not on their site if you ask (I have, and do).

I had an elusive leak I could never find in one of my five kegs.

I ended up filling a trash can full of water and dipping each pressurized keg completely underneath. Fixed the leaks I found.

Then, I replaced all the post o-rings, added some keg lube to the disconnects and started pressurizing each keg and disconnecting it for one day. If it still has pressure after 24 hours, I hook it up - otherwise, I know to avoid it.

Hope you pressure tested empty kegs.
