Which air line supplies air to your trailer air storage tanks?
Emergency air line
Emergency air line (normally red): The emergency line has two purposes. First, it supplies air to the trailer air tanks and secondly, the emergency line controls the emergency brakes on combination vehicles. Loss of air pressure in the emergency line causes the trailer emergency brakes to come on.
What is the proper way to test the air leakage rate?
Test air leakage rate: With a fully-charged air system (typically 125 psi), turn off the engine, release the parking brake, and time the air pressure drop. The loss rate should be less than 2 psi in 1 minute for single vehicles and less than 3 psi in 1 minute for combination vehicles.
Why is my airbag leaking in my RV?
Could be the compressor, could be the small auxiliary air dryer on it or an air line. Could also be a stuck relay or pressure switch controlling the compressor. I would start by locating the compressor (since it is loud, should be easy). Use soapy water and a toothbrush (never your own) to check for leaks. Where is that located?

Can a ruptured air bag keep up with a leak?
If (yes, big if) the air compressor can keep up with the leak (at present and if it grows) you are “free to move about the country”. But, there is also the possibility that you will be on the side of the road with a ruptured bag and air leak so substantial that your air brakes lock up. Thanks for the response.
