One Way Check Valve

Yeah there's no kink in the line and heaps of gas flow with out it connected. I didn't actually get them (I have 2) from evilbay. So ill call the retailer today when they open. Ill have them connect one up on there gas supply to see if they have working ones. Strange both are doing the same....

Reviving an old thread here but I am having the same issue.

Before I hooked them up I had my pressure at 12 psi and no dramas. 4 degrees, 3m of 5mm ID line.

Now with these fitted beers are pouring with 0 head.

Mine are the keg king jobbies, I'm considering returning them.
