i just replaced a new pump and still no water. here is a picture of the setup. I can't figure out what the clear hose and valve is for. Any help would be great. It's got to be something simple.
"Clear hose and valve" suggest you're probably referring to the winterizing tube so the pump can pull antifreeze from a jug ... obviously it should be turned to the off position during the camping season so the pump can draw water from the tank.
