[Richard and Rhonda]

My dessicant cartridge is in the same place. However, the air system is completely sealed from the outside elements, so the compromised state of the air system is not related to the location of the dessicant cartridge. My system is plumbed so that air from the big compressor on the engine, and air from the auxilliary compressor travels through the air dryer before it goes into the system.

I would suspect a couple of things if you have water in your system. One, the dessicant cartridge was not changed frequently enough. Two, you have a decent air leak and you keep your aux compressor running when docked. Either situaition could put a lot of wet air in your system.

Taking Tuga's lead, do you get water when you drain the air tanks under the coach? If so, the cartridge NEEDS to be changed.

When you said your system was compromised, could you elaborate?
