Glen,
Glad that worked...same thing happened to me.
The way I understand the system is this: your shore water supply hose connects into your water system. If your fill valve is closed, your water system can build pressure. The pressure can be supplied by either the shore water connection, or the on-board pump. If your fill valve is open, the pressure in the pipes is "relieved" back into your fresh water tank. Turning on the pump with the fill valve open simply pumps the water in a continuous closed loop: out of the tank, through the pump, into your water pipes, and back into the tank.
Somebody else may have a better explanation...
