You have three places to add water to your trailer. One is the black water flushing system and I think you have figured this one out. The second one is the city water hookup. It is a threaded fixture that will accept a garden hose. This one is used when you have a water source available and when turned on it functions like I mentioned in my earlier post.
The third one is the fresh water tank. It is used when you are going to be camping without access to water and want to draw from the onboard tank. It is behind the door on the side of the trailer and is simply an opening you can add water to. There is no way to hook it up and then walk away.
If you tried to fill the fresh water tank and walked away while the hose was running it would simply spill out of the fill spout. No water in the shower nor any in the sink.
