The line from the FW tank looks like it tees into it above the pump, its sort of hard to see as its buried behind a panel.. Is this as simple as it seems? Just open both the valves at the pump and the FW tank drains?
Another question, is there a back flow preventer that stops water from being pumped into the tank from the pump. There almost has to be or when i start pushing the RV antifreeze via the pump, it will go into the FW tank.
I have only had this rig for 3 weeks and the manual is sort of shore of details.
Thanks

Pumps have suction headers and discharge headers. Water flows in only one direction when the pump is running: from the suction side to the discharge side. The FW tank is on the suction side so nothing from the pump goes back to the FW tank when it is running.
You still need to identify the FW tank isolation valve or when you try to connect the antifreeze hose water from the FW tank will gravity flow out that opening; and when you run the pump after connecting the antifreeze it will suck from both the antifreeze bottle AND the FW tank. If the FW tank is empty you will air-lock the pump.
Maybe post a picture of your pump and surrounding area? For reference I have attached pictures of my pump area and tank drain valve.
