Sure can. That's indeed one way to do it. A lot of valves, have a little lever that will do just that but internally.Interesting! Can this limitation be "corrected" by running an extra line from the "non-used port (coupler)" back to the tank?
TIA, Dick
You can also put a Tee fitting between the quick disconnect and valve, then a shutoff valve and a hose back to the tank. That way, it's always set up and ready to go.
