Whelp, wife is almost home from work. Good luck. If your a Sooner I'll design your system cheap. I am an OU grad.

I forgot to mention this before - by upsizing all the mainline components, you can conserve enough pressure to 'get away' with smaller pipe in the zones themselves. (if you did have a 35 gpm flow, better to use at least 1-1/4 inch in the 'split' zone piping)

What are you reffering to as "split zone" piping? I assume I will have at least 1.5 mainline if not 2" then have 1.5" pgv valves. From there tee off and go 1" both ways... one side with 2 pgp and one side with 3. That's if I can get 40' of throw outta them

"Split" means you're running pipe in two directions from the zone valve with each one carrying about half the zone's flow.

You will not get a reliable 40 feet from a PGP unless the nozzles are bigger than standard and the pressure is higher.

You would be better off not settling on any part of the system design until you get the details on a water well. You might be working with lower pressures and closer head spacings.

You could be right. Its likely to end up being fed from city supply instead of well. I'm not giving.up on the well though till I'm told by someone who sees the property that its just not feasible...

Even if its a low gpm well why not get a storage tank and a centrifugal pump? You can always use the city as a back up fill line if the water level gets low in the tank

True true... good idea.... guess it all depends.on how much this well will cost. Can the drillers even give u an estimate? Or do they literally keep going till they hit water....

Find a well near to you and get the details.
