Thanks to all for the advisei am sure the leak is at the inflated valve and the plastic hose
"Inflated Valve", may I ask, what in the world is that? And, there's a few miles of "plastic hose" under our rigs and, there's different colors for different applications and purposes. At this point, it seems that you're not really sure just where the EXACT point of an air leak is yet. So, to "blindly" apply a internal sealer for a flat tire is, as most have already stated, and most likely will be, CATASTROPHIC to the rest of the air system.
So, what should be done, even if you're not all that familiar with the air system and all its components is, get spray bottle with some dish soap, (small amount) and water and create a solution that can be sprayed on each and every fitting, component, air line, connection, valve, air tank etc. You're obviously looking for any bubbles emanating from anything. Then, when you find that leak, and it can take a long time to find a leak since there's miles of tubing and, lots and lots of valves, fittings and more, then you do what's needed to repair it.
But, if you're not familiar with air systems and, all that's involved, well then either get someone who is familiar to help you or, take the coach into an appropriate repair center for your issue. Goofing around with an air system that has even 1/2 of the standard working pressure, can cause some pretty substantial injury if you're not sure of what you're doing and un-do and airline or fitting.
