Erm... the hell?

I don't know what kind of manifold you have, but when I got mine, I had to tape and tighten every fitting. I lost a 20 lb tank overnight. Check your pressure relief valve on the manifold. Mine was leaking, but I missed it on the soapy water test. I just replaced it with a plug and everything was fine.

I don't understand how you can even get that in the post upside down. Mine have a clip on the bottom that holds it in. The O-rings on the post and inside the quick disconnect should have kept it sealed. I think....

hey, I had a poppet spring that FELL OUT and the keg remained sealed and holding pressure until I tapped it. True story, I have the thread to prove it
