co2 pressure issues

[basisforaday]

So I just made a kegerator a few weeks ago and kegged my first beer. Everything worked fine...set the psi to 12 psi and left it for a week. I finished the keg this past week and moved on to the next. I now have 2 kegs of beer ready to go. I have a dual co2 regulator. I set the psi on the first keg to 12 but it seems like no matter how hard I try thats the max psi that I can get out of the regulator. I tried putting gas on the other keg but the psi won't go past 4 or so. I have used starsan to check for leaks everywhere and can't find any. My tank doesn't feel that full. Is there anything else I should look for? It's just weird that I can't set my psi to anything higher than 12 or so on the first keg and 4 on the 2nd.

Sounds like both regulators are defective. If there was a problem with the tank, the regulators would get stuck at the same pressure. If they are still under warranty, I'd send them back.

Do you have the locking nuts on the adjustment screws backed out?
