Glad to hear this works for you! I like the way your winterizing system works. It sure would be handy, as mine is a pita, having to crawl halfway into basement, remove trap door cover on wall, reach through small space to deal with winterizing hose.
I have also been in some CGs with very low water pressure, and water I didn't care to put in my tank. This is why I always travel with known good water in my fresh tank. Yes, the pump pressure is set, but at times can be much more than a poor CG supply/pump can produce, and more constant pressure during CG high use times.
