This one confuses me. Perhaps I'm stating the obvious. Is my 1990 Triple E the only one with a valve to switch from Tank Fill to City Water? If I leave it on Tank Fill, then the fresh water tank will overflow eventually and dump out the overflow spout on the passenger side. If I have it on City Water it won't, since it's diverted straight to the lines rather than the fresh water tank.
No, your rig is not the only one with that setup. The overfill problem arises though, when the check valve associated with the water pump fails, allowing city water to backfeed to the tank through the pump. Your "City/Fill" selector valve just bypasses the pump/check valve arrangement to fill the tank. I have the same setup.
Okay, yeah that makes sense. So set to City Water, the water can still get from the lines back to the pump. Then if the check valve fails it fills the tanks more. Obviously I didn't look at it that way. Thanks for clarifying that for me.
