I have a 500 gallon Storage tank on a "Water Tower". It is only 6 ft in the air from the ground and even with the bottom of my roof eves. But water flows fine out of my faucets, toilet and into the Tub. Now a Shower is another thing. I had to hook up a 12 volt pump to get my shower to spray out. But then I used a low volume shower head there.
I saw an appliction once where someone made a shower. They took a five gallon bucket with aprox 30 holes in it at the 7 ft mark and filled it with hot water. Took a shower under it.
