Happy 4th of July to all. Need some help with a semi new to me '03 Expedition 37U. We have owned it for about 4 months or so now and out on our first extended stay. We headed up to Oregon and set up, I noticed I was low on propane so decided to try out the electric heating element for the hot water for the first time.
We left the campground for a few hours and when we returned I noticed a small lake beneath the RV. My wife had left the pump on and the once full water tank was now at 1/4. The rear 2 bays on the passenger side were flooded with water streaming down from the light fixture above in each bay. Additional the majority of the water was coming from a small hose that exits just above the rear passenger side tires.
After a lot of trial and error I discovered putting the water heater into bypass allowed me to use the water via the pump and to eventually connect the city water and use it without further issue. Except of course that I have no hot water and a very unhappy camper wife
In addition to the flooded bays the carpet was soaked in the bedroom along the bed platform edge but did not get wet going into the bathroom or near the outside wall. I am assuming that some how a hose must of broke or a pipe split etc that runs either from or to the water heater that is located at the right rear of the coach.
Couple of questions, first does this sound like an accurate assumption from the vets out there? What exactly is the hose that exits above the rear wheels? Final question is, does anyone have any idea how to access this area? it appears to be above the bays but below in the inside floor so I am not sure how to gain access to the area to look for the root cause.
Thanks in advance for any and all help folks can provide!
