If your trailer does not have a grey water holding tank then I would believe this is a straight drain like stated.
I would test the draining issue separate from the pressure issue.
Take a bucket of water in and poor it in the sink with nothing connected and see what happens. If that is the low point drain for the water line it shouldn't make any difference if it is plugged or unplugged with water draining.
