Presently I am feeding the high pressure pump on my watermaker with a water puppy (1/2" ports), with 3/4" inlet and 1/2" outlet. and it just barely supplies the 3.5 gpm needed. This pump is rated at 6.3 gpm.
Jabsco makes a Maxi puppy, rated at 9.5 gpm, (1" ports). Given all else is the same (head, intake and outlet hose size, etc.) will the reduction in hose size cut the flow so that the maxi puppy will not pump significantly more than the water puppy?
