Sounds like you and neighbor need more water storage containers, to fill when the water is on?
Interesting idea, to plumb in a "share tube". I like it.

We have a lot of power outages with lines coming here along treed roads. In one extended one, before I had a generator, this neighbor had to get water for his toilets from the creek a quarter mile away. When the power was only out a few hours, they had run out of water to drink or brush their teeth. Even with a generator, I still keep bottled water and extra water for flushes. There are times that the well pump is broken. When that happens I can hook up to a next door neighbor and I've had them hook up to me.
If you don't have a few bottles of water, a flashlight, or a few extra batteries, you're a FUBAR loser.
