The #'s I quoted below came from a "pond construction" book I read a few
yrs
ago and I think they were for submersed pumps (don't know if that makes
any
difference for "out of pond" pumps) - seeing as how your info is newer and
for the pump you have, I would use it - there may be some one else in this
group that knows for sure - Good luck
Gale :~)

Whew! I was thinking I'd need ANOTHER new pump. Actually, the chart
indicates friction loss in that range for 1" pipe and high gph, so buying 2"
pipe may have saved me.
