On my rig there is no 'fill' position on the pressure shore water connection -- only the gravity feed to fill via a separate port. I would think that the overflow tube comes from near the top of the filler neck and would not sustain a siphon as the water level drops below overfull in the fresh water tank...

Ye Chuck, I'll give that a try. I can see, as I said the top of the tank. So I can stop it before it starts to flow thru the overflow. When it first happened I thought the tank had swollen from pressure (and maybe that's what got it started) and the flow would stop if it went down.
Ok running outside to do some test now. Got a neighbor coming over to have a look too.
