Does anyone know if that single inlet valve for city water or tank fill needs to be in tank fill position in order to use the pickup tube ?
The valve should be in the Normal position, not the tank fill position. When blowing out the lines, one would start with that valve in the fill tank position to blow out that line. Then, change the position back to normal to blow out the other lines. (If you have a black tank flush system, don't forget to blow out that line also.)
Since you are using a hose at the water pump to suction up the antifreeze, I assume you have the EZ winterizing system. The valve there determines whether or not the pump's suction is to the fresh water tank or to the winterizing hose. If it is pulling antifreeze out of the antifreeze bottle, that is the winterizing position for your pump.
When suction up the antifreeze, you need a faucet open. Yes, for us, that's a two person job, one handling the antifreeze and one handling the faucets. (And the problem is made unnecessarily harder by not having an on/off switch for the pump near the pump.)
Your owner's manual will tell you to have all of the cold water faucets open and close them as the "pink stuff" starts to flow. Then repeat for the hot water faucets.
In our situation, I handle the antifreeze; Sarah handles the faucets and pump switch. She open the cold water side of the kitchen sink and turns on the pump. When the antifreeze appears, she switches to the hot water side. When antifreeze jug is three quarters empty, I knock on the side of the RV and she turns off the pump. We continue through all of the faucets, toilet, toilet since, and outside shower.
