Power-Flo offers this version that is both ∆ T and P in one pump. I like this graph in the manual that indicates max. pressure, RH, cautions against certain fluids, and shows required pressure to prevent cavitation potential.

    According to a friend of mine who lives in P.A., you would not be able to use that pump because the R.H. is "over 100% all summer long". She will be visiting here this summer just so she can get out of the house. B)
