Ahh… that’s where you lost me. I don’t want the bubbles out, I want the pipe completely free from water before I take it apart. The physics I’m trying to figure out (and obviously not describing very well) is I need all of the water from this upstairs zone drained out, but it is going to be air-locked if I shut off both hand valves even if I attach a hose in between them. I’m guessing I need to figure out a way to introduce an air vent to allow water to flow out the hose, and I assumed the bleed screw was the most logical way.
