    As soon as I turn on the CO2, my pressure relief valve starts shooting out air. I can push on it with my finger and it stops. The gauge only reads about 12 psi, and I've turned the knob in the front as far as it will go.

    What am I missing?

    I'm guessing you're talking about a ball lock pull-to-release PRV. To be sure; is the ring in the down (lower) or closed position? Give it a good jiggle (quarter-turn) to make sure it is seated. If still leaking try to tighten with pliers (carefully). If still leaking I would swap out with another PRV to make sure it's the valve that is defective. Replacement cost is under ten bucks.

    Do you by chance have anything suspended inside the keg from the underside of the keg lid? Like maybe a sack of dry hops on a string tied to a SS hose clamp? I have had some past issues with the extra string/floss dangling and getting sucked into the PRV when burping my keg. Causes the PRV to stay open all the time. Have to remove the keg lid, pull the floss out, cut it off, and then reseat the lid and burp again.

    I've had an issue before where the plastic threads of the PRV didn't align with the metal threads on the lid and the PRV whole I was screwing it into place and it kind of just made its own course. Then it didn't hold pressure till I got the threading right. You would have probably realized though if this is what happened to you.

    And by the way, I just shake my head every time I see the replacement cost of those PRVs at my LHBS. That pretty much goes for any lid related part, save the o-rings.

    Sorry guys I forgot to specify: it's the PRV on the REGULATOR, not the keg

    I had a similar problem with a cheap regulator. Take the valve off and check out the mechanicals. Or put a plug on it. Shouldn't really need it if you have pros on the kegs

    Same happened to me. Took the valve apart. There is a black rubber seal, flipped it over and issue solved. Been good for about 2 years since. Be careful, very small parts inside, that are hard to locate once dropped on the floor, obviously speaking from experience!! Good luck.

    Just be glad you have a prv on your regulator...I have several that don't...But the ones that don't, work fine anyway :slight_smile:

    Hint: take it off and plug it. Caveat: not cleared with OSHA :slight_smile:

    Sorry to hear that. Then, as others have said, plug it up.

    I would think the hardware store could sell you an end stop if you brought in the regulator. Not positive

    Unscrew the relief valve and replace it with a 1/4" NPT plug from any hardware store. Or buy a new PRV. I think they are around 10-15$
