Water system issue...

[mdbrill]

Hello,

I have a 1985 Winnebago Chieftain. I have never used the water system before. I went to winterize it today. When turning on the water pump, the fluids in the potable tank spray out of the EXTERNAL fill. Does anyone know why this would happen? Is there something you are supposed to screw on to block the EXTERNAL water fill when not using it?

Thanks!

I assume by external fill you mean City Water Inlet, they have check valves built into them which are supposed to stop water from flowing out of them. It sounds like yours is broken or stuck open.

I had one that leaked on our old coach but had a screw-on cap like this one which sealed it well. I could also make it spray by pushing a small button-like protrusion in the center of the inlet, sometimes when I let go it would leak a little less.

There is usually a check valve there.. Its prolly bad. Most people just go ahead and install a ball valve instead.
