C02 Pressure reg issue

[Addiktion]

So I was cleaning a keg and didn't realize I closed the valve with the C02 was on. I came back and that sucker maxed out my gauge. I released the pressure and went about my day. I just kegged my beer tonight and noticed the first gauge was set to 12-13PSI. The second wasn't connected to a keg (and was the one I let get really high) and it was well beyond maxed out. The valve was completely off and should be at 0psi. Its a flex keg duel c02 regulator. So basically when the valve is off its building pressure. Does this sound like a rebuild kit? I now have to use the bad gas line so it wont over pressurize when its not hooked up to anything.

By "valve" do you mean the quarter-turn shut-off valve on the low-pressure output of the regulator?
Closing shut-off valves should never cause a problem with the regulator regardless of the pressure setting.
I do it all the time - both the shut-off right at the reg and the shut-offs on manifolds down stream - and on multiple regulator makes/models (Taprite, Micromatic, Chudnow - they all behave the same).

In any case, if you have the "bad" regulator dialed down to where there should be no pressure on its output, and you have released the held pressure on the output (ie: open the shut-off valve briefly), but its output pressure gauge is still reading pressure above zero, it would indeed indicate a problem with the regulator.

But that could be as simple as a bit of crud stuck in the pin valve seat, which you might be able to clear thusly:

- close the cylinder valve
- turn the "bad" regulator pressure control a few turns like you were dialing up a high pressure setting (ie: clockwise)
- open the shut-off valve below the regulator - and remove any attached gas line
- get a good grip on the cylinder and open the cylinder valve for a short blast or two.

To see if it worked:
- dial the regulator down to "zero"
- close the shut-off valve
- slowly open the cylinder valve and observe the "bad" regulator's pressure gauge.

So the idea is to make the "gap" at the pin valve seat as large as possible by cranking the pressure setting up in the hope that a crud particle can be flushed out by the cylinder pressure.

If that doesn't clear the problem the next step is to rebuild the regulator...

Cheers!

Thanks, yeah not the quarter turn valve. It's the pressure adjustment. Basically if I set the pressure on my first valve assembly the second one will build pressure even though the pressure adjuster is all the way off or left. If I switch the gas lines on my keg to the second one no pressure builds in the first which is good. Before I could set these both individually with no issues.

Ok, terminology got in the way a bit
But there is no connection on the low pressure side between regulators (unless you have the outputs plumbed together) so if one side is having a problem, that's the side with the problem.

I'd still start with the "blast out" to see if that clears up the problem, it's worked for me a couple of times (after hooking up a freshly filled cylinder).
And if that doesn't set things right it's rebuild time...

Cheers!

Okay I'll give hat a try. Thanks man
