I went to HF today to get a fountain pump for my sink that I had set
up.

Guess what the pump didn't live up to it's specification. it was
rated at 158gph with a 3.6 foot rise. It only trickled at 30
inches...

You are at the mercy of the General Energy Equation.

Without a performance curve, (Head Vs Flow), pumps will publish max
head at no flow as well as max flow at zero head.

There ain't no free lunch.

BTW, "Head" = output pressure.
