How to Find and Fix a Leak in a Regulator

How to find a leak in a regulator Hey everybody, this is Anthony at the Beverage Factory. We’re here today to find a leak in your CO2 system. What we’re looking at today is a Kegco premium dual product, dual gauge regulator hooked up to our standard 5 pound CO2 tank. And all that is hooked up to two Kegco 5 gallon ball lock kegs. The first thing we’re going to do to locate your leak is we’re going to pressurize the regulator and then isolate it. To pressure it, you just need to turn your tank on, which is counter clockwise. Turn it on to where you get a reading here you should be reading between 500 and 1000 psi that can vary depending on how cold the tank is, the temperature, altitude, and such. But don’t worry about it, all you need is a reading for this test. If that needle moves at all, you should be good. The next thing we’re going to do is we’re going to put some pressure on the low pressure side, so that would be going out, what would be going out to your kegs. You do that by turning the handle clockwise until you get about 10 pounds of psi or 10 pounds of pressure. Once you get the regulator set at 10 psi make sure your valves going out of the regulator are shut off at 90 degrees and then turn your tank off. After you get the tank turned off you’re going to want to look at your low pressure gauge and see if you notice the pin on the, or the needle on the gauge moving at all. If it is dropping, you have a leak somewhere between the shut-off valves and the tank. The main place this leaks is right here at the CO2 tank where you’ll need to tighten this with either a specialty tank wrench or a large crescent wrench. Don’t be afraid of this one, you do need to tighten it. Any leak in the regulator can be fixed with teflon or sometimes just snugging it with the wrench. If you have any questions about how to do that feel free to call our technical support. If nothing moves in this and your regulator seems to be holding pressure leave it for 15 to 20 minutes and then come back to it, and just see if that needle has dropped at all. Sometimes you can have a really small leak in your regulator and you just want to give it time to see if there’s any kind of leak in the system right here. If there’s not after you come back from 15 minutes you go ahead and open these up one at a time. So just open this and expose this line to your keg to the pressure and if this falls at all, this needle falls at all you’ll know that that line that you opened up and got the fall has a leak in it between the shut-off valve and the keg. Kind of narrows it down so when you do go to do your leak check you will have an area to look at. So if you notice a leak get that line pressurized and then spray all the connections. Threaded connections, hose connections, ball lock connections, and then all the o-rings on the keg with some foaming agent. You can either use Windex, Simple Green, I use Star San because I’m a home brewer and it foams really well. And that will show you where your leak is. If you can’t find a leak at that point, if you don’t see anything but you know you’re losing CO2, give our technical support a call and we’ll try to help you figure it out. 1-800-710-9939. Make.

  1. Having issues with a CO2 leak in the regulator on our Kegerator setup and was looking for some guidance on how to fix it.

    Great quality video, really clear and simple instructions that helped us immensely.

    Great stuff – thank you!

  2. My reg came with a plastic o-ring kinda "built into" the end of the connection post. When I went for refill, the gas guy gave me a larger plastic washer to put between the reg and the tank, Do I need both? Thanks
