Default Regulator problems

Have a dual regulator. One works just fine. I hooked up a keg today and the regulator I'm not using goes up to 50psi even with the valve closed. Can anyone tell me what I need to replace to fix the issue? I've attached a photo so you can see what I'm talking about. The regulator on the left is the one that goes to 50psi. The one on the right holds steady where ever I set it.

Double check that you have the ports connected correctly

Not completely sure of your set up. If the regulator on the left is dependent on the set output from the regulator on the right - the reg on the left is bad. Cant get more pressure out than pressure in.

If the reg input on the left is receiving full pressure from the tank, the reg is bad, it should be able to dial down the pressure.

Either way, I'd say the reg on the left is faulty.

Is their a high pressure gage to the left of the regulator on the left? If so, what does it read?

Edit.. and plus one to what Helibrewer said. Not sure why, but he is probably on to something.

The ports are connected right. The regulator on the left is independent from the one on the right. The high pressure gauge is reading 600 psi (my tank is almost empty). I wasn't sure if the valve was bad or the regulator was bad. Seems weird that the valve is shut off but gas is still making it through.

Maybe the gauge is stuck? Is that a bleed valve I see? If the one on the left has one can you pull it and the needle should dip momentarily if not stuck.

There could be something on the diphragm in the second body, causing the issue. If pulling the relief valve doesn't help, or help for long plan to take it apart and fix. I had a similar issue with a regulator when the gas flow was off, less issue (but still there) with it open.

IF you can get a rebuild kit for the body, I would do so. Otherwise, I'd replace it with a Taprite regulator.

BTW, if the CO2 tank is in the fridge, 600psi is pretty full. You normally show about 300psi lower when the tank is at fridge temps.

You can't say if it's pretty full or pretty empty, just that there's still liquid CO2 in it. The only way to know is to weigh the tank.

The regulator will show a pressure difference depending on temperature of the tank/CO2. I had a full tank show 800psi at room temp and 500psi after 24 hours in the brew fridge (at ~40F). This is a pressure difference, not volume difference. IME, when the high pressure guage is in the red, or getting lower than that, it's almost empty. Tank size often determines how long you'll have between getting low and running out.

I'm not disagreeing with any of that, just your statement saying "600psi is pretty full." 600 psi could mean the tank has one drop of liquid CO2 left in it.

When I pull the bleed valve the psi drops, but when I release it the psi goes right back up. I guess the best thing to do is try and find a rebuild kit.
