Dual regulator pressure creep

[atomicpunk]

Why do you want to set the second at 0 psi? Why not something normal like 10-12? If you have a shut off vale on the output for the second then you won't lose CO2 is that is what you are worried about.

I don't presently have another keg attached to the second regulator and the output valve IS shut off, so I'm not losing CO2, but with the regulator screw backed out, the pressure goes up to 18 psi over a day or two, maybe higher if I let it before bleeding it off. My thought is that with the regulator set to zero, if it goes to 18 psi on its own, what will it do when I set the regulator to 10 or 12 psi? Will it continue to climb from there? That would defeat the purpose of a regulator and I could get over carbonated beer.

Ah! I thought you were trying to maintain 0 psi and it was creeping up from there. If you set it to a "normal" number and it moves up then I'd say it is faulty.

Well? What does it do?

I'm really glad someone else posted about this. I have the exact same problem with my "chudnow" dual reg setup from KegConnection.com. I see some very strange behavior I didn't expect after fiddling with a friend's two reg setup.

Let's say both regulators are hooked up and pressurized to 15 PSI. If I close the valve and disconnect the second reg without first turning the pressure all the way down, the pressure gauge on that reg will slowly climb over several minutes, finally triggering the emergency valves and dumping a load of CO2 (and freezing the second regulator). It will continue to cycle this way until I unscrew the regulator all the way...

Is this normal? Is there something wrong with the regulator?

Sounds like something is very wrong. Shutting the valve would be no different than when the pressure in the keg equalizes when it is still connected. Sounds like your regulator is not regulating. Did you assemble this or did come preassembled? Possible your first regulator is the bad one.

That's kinda what I was thinking. I didn't assemble it... it came preassembled from KegConnection.com. Is there a way I can isolate these two and figure out which one is faulty? Could this be because the regulator is really close to the cold plate in my fridge?

Your comment about the equalization of the pressure in the keg was spot on to what I was thinking. I'm afraid I'm going to turn off the low pressure side one of these days and my CO2 will dump all day while I'm at work.

You could disassemble them and connect one up at a time and see what happens. Hopefully kegconnections would simply send you a new one in return without going through all that trouble.

Pressurize your kegs, disconnect the gas lines and turn off your tank. This way you won't lose CO2 and your beer will still be carbonated. You can even pull a few pints without the gas on. When it starts slowing hit with some gas until you get the probalem worked out.
