are you going to use a pressure tank with pressure switch? if not be careful with the hydrants, you dont want to close the hydrant with the pump running(dead- heading)this will burn up your pump pretty quick even though most pumps now have thermal protection....the cost difference between 3/4 inch and 1 inch or even 1 1/4 wouldnt be much difference so you might just want to go with something bigger...sorry esshup didnt see your recommendation smile ...you are right the bigger would be the better way to go...especially since the cost isnt much of an issue ...almost forgot okie...if you decide to use the flow reducer remember when you open your hydrant you will only get 2-3 gpm depending on what size reducer you get...unless you can plumb the reducer after the hydrant before it hits the pond..you could have a hydrant for general purpose then closer to the pond you could have the hydrant that is reduced...for comparison a shower head puts out about 2-3 gallons per min
