Getting water out of my rain barrel

No, not at the barrel spigot. Pressure there is determined by the height of water above the spigot, the same 0.433 PSI/foot, not the elevation of the barrel.

If you raise the barrel 10 feet, and leave the hose end at the same point, the pressure at the hose end will be 4.33PSI higher than it was before you raised the barrel.

The pressure at the barrel's spigot did not change.

Yes you are correct, I realized that as soon as I posted. The pressure at the end of the hose would increase by 0.433 psi per foot of height. I was thinking about loss in the hose. The pressure would be 0.433 psi per foot at the spigot but something lower at the end of a hose.
