Right, GPM not GPH. The floating fountains equate to approx 60 to 70
GPH or so or they rate them at 4500 to 5200GPH, which is gong to put
you in the same figures as GPH listd above...........Just seems
awfully small but then again I am comparing to a 185 GPM pump pushing
it to 8 feet head above water surface and approx 40 feet or so
horozontal run. I figured it at 185 with friction and head loss, but
it is capable of 290 gpm flat out.
I think I am gonna give the 6x gpm sub type pump a try just like is
use don the Sugar Creek Fountains, and at most all it will have to do
is push 1 or so feet of head to thr nozzle........so flow rate loss
shuld be minimal. I'd like to get the fountain head to just come out
even with the ponds water level or else shoot for as high and wide a
spread and prhaps add a venturi from a hot tube setup in the plumbing,
unless there is another way to infuse air into thr discharge pipe with
a series of Y's and reducers etc...........not really sure if it would
work or knot.
