Regardless of whether a trailer has a conventional gravity fill for the fresh water holding tank or has been saddled with some form of over complicated valving system to direct potable water into the trailer the simpler solution is to ignore it all. Instead, invest in a 12 vdc potable water pump, mount it on the trailer somewhere you deem convenient, and plumb the pump's output directly to the tank.

Now that IS complicated! Why not just use the on-board pump to draw the water in like I explained earlier?
Nope, not complicated at all ... I've done one variation or another of this mod on every trailer we've owned, going all the way back to our popups. Simpler because there are no valves to reset, better (for us) as a separate fresh water transfer pump doesn't prevent my wife from using the trailer's system at the same time I may be transferring water, and third, it cost me nothing because the pump I'm using for transfer is the trailer's original pump which I replaced with a Shurflo Revolution. Win - Win. :B
