Continuous Water Drain when using "City Water"
After setting up camp, and taking the family to Six Flags for the day, I came back to find a nice little pond on the passenger side of our 2012 Charleston. I could see water draining from a spout behind the last main storage bay (under the door that is held shut with two cotter pins).
It appears that having the "city" water supply hooked up fills our water tank and then proceeds to overflow. I'm confused as to why I have 2 water fills (one for the tank and one for city water) if the city one fills the tank and then overflows. I turned off the city supply and turned on the water pump, and the "leak" promptly stopped.
What am I missing here? Is there a valve I need to close somewhere? Do I have a more serious problem that needs to be fixed?
