So I've recently built a four tap kegerator to house my homebrewed beers. I've been having a lot of trouble with my co2. I have a five pound tank with a dual body regulator that I feed into a four way keg manifold that flows to my four kegs. I set the regulator to dispensing pressures and beer flows from my tap no problem, but after a day or two the regulator boddy gauge falls to zero psi. If left open eventually all gauges go down to zero and the tank is empty. All my connections are tightly hose clamped and I have replaced the manifold already to be sure that wasn't a problem. I've done leak tests on all my connections and haven't noticed any leaks. I'm thinking the regulator is the problem it is about two years old and has some wear and tear but, I don't wanna spend regulator money if I don't have to, especially after blindly replacing the manifold. Does anyone have any advice on something like this?
Have you tried isolating the leak? If the 45 psi trick Doug suggests doesn't get you anywhere try turning on the tank and shutting all 4 of the lines coming out of the manifold when the pressure is stable shut off the tank. Let it sit over night, if the pressure if the same you know its between the manifold and one of your kegs. Do the same thing turning on one keg at a time and you should be able to isolate the leak and then spray the heck out of that area with soapy water. Even after you find the leak keep looking for others. Granted if you turn it up to 45 PSI you should really be able to find it quickly but isolation is how I've found leaks in the past.
in addition to the good advice provided, turn off the kegerator when checking for a leak. turn off the radio too. everything. with the pressure up to 45 psi you will be surprised to hear the leak. does your regulator have an inline quarter turn valve? the one with the red handle? turn up the gas. pressure. turn off the valve. if the low pressure gauge eventually drops to 0 psi you know the leak is at your regulator, and if it stays then it's after. Cheers.,
How did you fix the leak? I am having the same issue. I charged up all 3 of my taps, shut off the main and sprayed a water/dishsoap solution to find the leaks on all connections with no sign of leaks. Yes, I've also tested the main valve this same way.
