I've read where there are valves to drain moisture from the air tanks under the front of most CC's. I've really not taken time to locate them yet since I recently had the air dryer cartridge replaced.

However, I do have two valves in the engine bay on the lower right. I opened them and used them to drain all the air so I could replace a defective shrader quick-connect in the bay under the driver's window. Do the two valves in the rear suffice or are they in addition to drain valves up front?

The valves are visible because they are attached to the low point of the tanks. If you get eyes on them, look for plastic coated wire cables leading to one side or the other. In my rv they lead to a brace in the propane compartment. I open the hatch and pull the cables.

You should find the valves under the front of the coach on the driver's side. They are visable from the front.

Ours is a switch in the Center of the dash.

Are you sure that isn't just a dump valve to deflate the air bag suspension? Usually purge valves are on the low points of the air tanks, the dump valve is just an electric solenoid on the air line to the air bags.

Our Magna has an air purge switch in our control cabinet for the Silverleaf system directly behind the driver's seat. The switch is called Air Tank Water purge.

Our ancient CC has a air valve purge rocker switch on the dash console to the left of the driver. Your 2007 may have one as well.

That switch eliminates the need to locate strings to pull for each individual tank to dewater the tanks like some other rigs.

We have switch for suspension and switch for tanks.

can be fun if tanks are full and someone is standing near where the out hose is, they jump real good.

Most CC should have electric valves for the tanks, airbags may be included in the air leveling or hyd leveling systems, and like ours, may have an additional switch somewhere else depending on the model year.
