I have one of the valves that you can hook up to the hose and then have to press the relief button to let air out as you go, but my question is how do you add water PLUS another fluid like washer fluid with this setup? There is no way to draw fluid from another container is there? I would like to fill the tires on my B7100, but I don't want corrosion, and even though I'm in MS, we could still have a freeze, so I would definitely need something other than just water.
