Question Fresh Water fill from City Inlet question

In a previous Fresh Water Thread
>http://www.airforums.com/forums/f443...ase-66637.html<http://www .airforums.com/forums/f443/need-diagram-explained-please-66637.html

the valved bi-pass loop around the pump was discussed.
If one opens that bipass valve and is filling the (under the floor) Fresh Tank that way;What happens if you do not turn it shut after it is filled.
Does it equalize and just quit, or is there an overflow?

Based on the diagram in the other thread the output side of the pump would never pressurize since water would be returning to the input side of the pump. My guess is that the pump would run forever, pumping the same water around the loop.

Thanks Richard, but my question does not address that exact diagram. Mine is under floor tank, that diagram if I recall is an above floor.
Not that that would make any difference, (or would it)?

Would the pressure from the city line finally fill the Fresh Tank and then push water back up and out of the manual fill door outside the trailer curbside? (That is if the valve ws not shut off after filling).

If the city supply line is shut off, there is no additional water to overfill the tank. The I don't think the location of the tank would make any difference.

Maybe, if the fill cap is off. It also might burst the tank or raise the floor. There have been incidents of serious damage from overfilling.

You need the manual fill door open to let the air out when filling. When full, the water will come out the fill door and keep the pressure from blowing the tank.

If in fact the Fresh Tank is in danger from over filling while connected to City Water, then there should be a laminated or engraved warning sign/decal/plaquard prominently visible near the valve knob.
I have never seen such a warning label nor read of this over fill danger. I keep a rubber plug (cork) in the manual fill line behind the fill door to keep bugs & dirt out. I assume City pressure would pop it out. Next time I am hooked up I will experiment. The storage lot has no water or I'd go do it sooner.
BTW you can get the rubber corks at Lowes or most any hardware store.

My '91 has a system built in...although I have only used it once...
AutoFill...it's a button buy the pump switch. Turn off the pump, hit 'AutoFill' and it energizes a 12v solenoid (where your proposed manual valve is inserted) UNTIL THE TANK IS 3/4 FULL. Then it shuts off, supposedly...
