Help with Micromatic Gas Blender

[trappist]

I have been having problems with the gas on my draft system, it is getting worse by the day and no one seems to be able to help, I am using a micromatic blender at 60% co2 40% nitrogen, currently nitrogen tanks empties out at a ratio of at least 5 or 6 to one. I am hemorrhaging nitrogen, I cant find any leaks, I have had the installer out many times (twice in the past two days) he cant find any leaks either. I suspect the Micromatic Gas Blender is broken, I called Micromatic last week, they said they would call mc dantum and get back to me, so far they have not, any one have any ideas? I am sick of changing nitrogen tanks.

There is a shut off on the blender. turn it off and note the needle position on the nitrogen and CO2 regulator. Turn it on, if the regulator needle drops and stays down, there is a leak between the blender and the kegs. If the needle does not move, there is a leak at the regulator or blender.
