Or do you just shut Off the filling Source before the “FULL” LED lights up to prevent bursting the tank/plumbing?
My previous RVs had an overfill vent next to the fill port & if your standing next to it, you get doused when it’s full!
Good question! I have a 2020 Rockwood 2902SW travel trailer. When I fill the water tank full, I soon observe a water leak emitting on the underside of the trailer from the area of the tank. The water is seeping through a patch seam in the underside. I do NOT observe any over flow line exiting below the trailer membrane. When I dump a small amount of water from the tank, the water leak stops. Due
to the position of the water tank, it is impossible to observe the connection areas of the over flow and fill line. I suspect the problem is the overflow line allowing water to exit the tank to the ground. ANY experiences with this style of issue will be appreciated!
