So I moved recently and had to tear down the kegerator for transporting. I set it back up and checked the CO2 system. Had a leak. I finally think I found the leak (or at least I found the one!) but I am not sure what is actually leaking.
Here is my set-up. My primary regulator goes goes to a T with 2 shutoffs. One shut off goes to a 1/4" barbed swivel nut and a QD for purging kegs, etc. The second shut-off then leads to a bank of 3 secondary regulators. I was actually only running two of them previously as I had an unidentified leak in the 3rd
The secondaries lead to 2 seperate 2 part manifolds inside the kegerator.
I ended up dunking the connections on the bottom of the secondaries in some starsan. They are connected with barbed swivel nuts. I cranked the pressure up and turned on the gas. What I saw is many very fine bubbles coming from around the hose clamp itself? I have the hose clamped on the swivel nut with the worm gear type hose clamps. I do not think they are clamped down too tight. Maybe it is coming from somewhere else? The only thing I can think is that the clamps somehow punctured the hose itself?
