Last night we landed in a new campground in Advance, NC. Sometime shortly after we hooked up the water, the pressure dropped to a trickle. I flushed the toilet and everything seemed normal and never gave it more thought. About a half hour later Bonnie came screaming out of the bathroom that the toilet was going to overflow. Thank goodness that she caught it when she did. It was within a quarter inch of going over the top. Another flush emptied the bowl - immediate crisis resolved! Again everything appeared to work properly. The gizmo on the back of the bowl allowed water to run in to cover the bottom. Only it didn't stop running and started to slowly fill the bowl again. Crisis temporarily averted by turning the water off outside. Later in the evening the pressure returned and we had no further problem with the trickling water.
Apparently the gizmo that admits water into the bowl after a flush requires a certain amount of water pressure to shut off. The trickle we experienced wasn't enough pressure to shut it off.
Oh, and one last comment. Here's some ammunition for the guys. I left the lid up after using the toilet making the impending overflow readily visible. Had the lid been closed in the female way, the overflow would not have been seen until the waterfall began.
