Beer Mix problem

I made BM's Smoked Porter recipe a few weeks ago (a real treat, as if you didn't already know) and kegged, carbed, and used a Nitro setup to serve this delicious ambrosia pushing with Beer Mix.

So I go to over to the old "keezer" to pour myself a mug of the stuff when I notice that all my gauges read zero and I still have half a keg left. Here is the interesting part though: I had perfect pours for about a week and a half with no problems and my pressures were fine. It's almost like the leak was sudden from one day to the next.

Here's my setup:

Refurb Corny keg (seals were replaced and this is the first use on it)
Nitro tap setup from Northern with 5 lb tank (kept in the keezer also)
7.1 keezer, unaltered (at this point) kept at 41 degrees Fahrenheit.


I don't know if any of these variables can contribute to this problem but I figured I'd mention them. This is my first time using Beer Mix and a friend has the same setup and the same thing happend to him after about a week or so. I've checked the lines and connections and nothing seems to be leaking or loose.

Has anyone had this happen or have any observations as to what to do or what I can try and fix?

 

Unless your tank didn't get filled properly and you wound up with a really short fill, it sounds like you've got a leak somewhere. It could either be a really slow leak (which is why you didn't notice right away), or something could have blown a little due to the higher pressures involved.

When you say you checked for a leak, was that with gas flowing, or just testing each of the clamps/connections? If you haven't run gas through yet, you're going to have to fill up your tank again and start the gas flowing, then spray with something that can bubble if gas is coming out (I like starsan, but soapy water will work too). If you want to save your beergas, you can hook up a CO2 tank instead and run it through, but you'll have to make sure at some point you test the nitro regulator/tank if that doesn't find the leak.
