We woke up to 8-10 gallons of water across our living room and bedroom floor. Even more water was outside and had formed a river down the campgrounds driveway, by way of the potable water connection purging water through the vent hole.
Not sure why having city water hooked up (it was hooked up to the drivers side "City Water Connection", not the fresh water connection side on the passenger) but I read that a bad valve in the water pump can allow water to fill the system and then backfill into the potable. We did our best to remove all standing water.
Anyways, besides getting the factory defect fixed, I'm most worried about now owning a completely waterlogged TT that is just 2 days from the dealer. Without pulling up the floor, I don't see how the manufacturers warranty can guarantee there isn't water damage to the subfloor.
Anyways, we're happy to be here, even if our first night didn't go smoothly!

Congrats on your new rig.
You are correct about the check valve.
Your on-board water pump has a check valve built into it to keep the city water from back flowing into the fresh tank. (or sometimes out the antifreeze.winterizing port if that valve is turned) The two systems (fresh and city) are actually one system hooked together through the internal plumbing.
Debris (plastic shavings/sawdust) can get in the valve and hold it slightly open. The pressure of the city water pushes water past the partially opened check valve and fills the tank. It is unfortunate it ran inside your camper but fortunate that it didn't expand the tank to the point of bursting the tank or breaking its mounting braces from expansion. We've seen reports of that happening.
Usually if you turn off the city water, relieve the pressure at a faucet, turn on the on-board pump and allow some water to flow from the pump it might clear the debris. Turn off the pump, open a faucet and relieve the pressure and turn the city water back on.
If it doesn't clear with the procedure above, you are going to need the pump replaced/repaired or add a separate check valve.
In the interim, if you can't get it to stop back filling, open the drain valve for the fresh tank and let the water run out there. Only turn on the city water at the pedestal when you need water for now or simply disconnect the city water and use what is in the tank.
Best of luck getting you water problems resolved.
