I am trying to winterize an outdoor hose bib that is fed from a valve in the warm area of the building. The valve is a stop-waste valve that looks like it was installed backwards, so it is just a ball valve for my purposes.
The line past the valve was full of air when I found it last spring. I opened the valve and used the spigot through the warm months. Now that winter is approaching, I need to remove this water again. How was that water removed before?
The only solutions I have come up with are forcing compressed air into my water supply lines through the spigot (ew!) or installing a drain valve after the existing valve. Do I have other options?
