Hey guys,
I have had a Co2 leak on my system that I have tried to diagnose for weeks and I simply cannot figure it out. The situation is essentially as follow: I am running 3 sanke kegs from a 4 port manifold, which is in turn connected to the output of my regulator. The sanke kegs all use commercial style "D" couplers. When I pressurize the system, close the ball valves on the manifold, and shut off the pressure from the Co2 tank to the regulator, I lose no pressure over a 48 hour period. When I pressurize the system, open the manifolds, thus sending Co2 to the kegs, and shut off the Co2 tank, the system goes to 0 PSI after 6 - 12 hours. This should mean that the Co2 leak is after the manifold. Now, I took the following steps to locate the leak, to no avail:
1. Submerge manifold in water to find bubbles. No bubbles, even after 2 minutes of watching;
2. Leak test regulator output. No leaks. I even retaped the connection anyway and tested again;
3. Leak test all "D" couplers. I performed this leak test by submerging the coupler in water with the system pressurized. I found no gas leaks, even around the pressure relief valve and Co2 connections;
4. Leak test sanke kegs. I performed this leak test by filling the top of the sanke keg with water to see whether the valve might have a slow leak. Again, no bubbles; and
5. Leak test sanke kegs with D couplers installed. I wanted to see if the sanke kegs leaked only when the coupler was installed. For this, I filled the top with water to see if gas leaked from around the edges of the coupler while installed on the keg. No leaks.
I have no idea what to do from here and any suggestions would be fantastic. This sounds absurd, but the only thing I can think of is that the hoses themselves are losing pressure, because all the connections appear to be airtight. Is this even possible?
