This information seems confusing to me, and I am having a hard time believing it. Hopefully a factory rep will chime in.

You do look confused in your picture... (which I like very much, no jab intended)
We each live in our own little world of life events.
What are you having a hard time believing?
I would really like a factory rep post also.
He can even send me a private e-mail so that we can 'talk'.

The pump apparently has a bad seal that is allowing water to flow from the city water connection through the pump into the fresh water tank!!!

I immediately called the manager of the service department and told him what had happened before and what is going on now. He says he is going to send someone out to the campsite on Friday to look at it. I told him to make sure he brings a water pump because this one is bad.
Water pump and check valve on city water input replaced by the dealer this morning. No more cycling from the water pump and no leaks from city water input. Crossing my fingers that this issue is resolved.

Note: I have added a valve to the overflow. It will stay open until I dry camp next.

You were right that the siphon effect drained the tank, but this led to other problems later on with a fried water pump. Needless to say, I won't be leaving the water pump on while underway again.

Water pump should be off whenever not in the coach. These are plastic pipes, and there is alot of vibration and movement when being hauled down the road, and even vibration while camped. Good practice to keep pump off whenever you are not in a position to hear the pump running. IMO, of course.

That has not been my practice, I leave it on when I am using the fresh water tank but I may have to reconsider. If I had a pipe fail while out for the day, I could come back to find the contents of the fresh water tank on the floor.

I had a similar issue with my defective water pump, I happened to be in the coach at the time fortunately. I heard some water running outside. I went to investigate and noticed it was coming out if the fresh water overflow. This was interesting as nothing was hooked up to the fresh water fill and I was running off of city water. I turned off the shore water and eventually the water stopped coming out of the overflow. Turns out a bad seal in the defective water pump allowed water to completely fill the fresh water tank over a period of four days!

I now turn off city water when I leave the site for the day as well as turn off the water pump.

Did you have a pressure reducer on the 'city line hose'? All city line 'pressures' are not the same and many may be to high for the plastic lines and seals of a RV.

imo Everyone should always use a pressure reducer on all city lines.

I had the siphoning issue through the vent tube on a previous unit. The solution was to splice in a section of vent tubing that was long enough to make a loop that rose higher than the holding tank. Of course the access to the tubing was easy on that unit. Had no more siphoning issues and the vent (overflow) still functioned as it should.
