Transferring water

There is no need to buy a water pump, your trailer already has one.

OR as already suggested - invest in a second pump, leave the trailer entirely as is, and avoid having to switch any valves at all every time you want to use that on-board primary pump to transfer water then have to switch them back again. MOST importantly, you also won't have your wife yelling at you when she discovers she can't run water in the trailer while you're going through your water transfer process. :E

Right... Turning two valves is so much more work than dragging out a second pump, hooking up the power wires, and connecting the hoses. :B

Six of one, half dozen of the other, makes no difference at all. In my case, I've installed a spare pump in a G24 battery box mounted on the trailer's A frame and plumbed the pump output directly to the fresh water tank, 12 vdc is supplied to the pump with the trailer's own 7-pin Bargman connector which would otherwise just be hanging there doing nothing. So there is no "setting up", no valves to turn ... all I do is stick the pump intake draw tube into an Aquatainer of fresh water that's already sitting in the back of my truck and turn on the pump. While this process is going on my wife can continue to use the trailer's water system in any way she may choose, including showering.

And at least with my setup, there's still pressure in the water lines from our 2-gallon accumulator tank when the main tank is filling.

That 2 gal accumulator tank reserve won't be anywhere near enough if someone wants to shower while a single pump system has been re-valved for transferring water. :E
