<br />You can run 3 zones, (technically would be 1 zone if run at the same time), but you will have to change your pump if you add more later. Plus you'll probably need a 30 gpm pump (3 x 10 gpm/zone) to do that and that starts to get costly $$$. My suggestion..size your pump for 1 zone, put in control valves for each zone..don't try to run everything at the same time...that way you can put in a hundred zones and use the same pump.

Yeah, you're not kidding. Pumps can be big $. I'm thinking to get an efficient pump to at least handle one zone at a time.

Alright guys,
I've mapped out my first zone, GPM requirements. I will have to cover a 56' x 36' (2016 sq.feet) front lawn for the first zone. I figure I will need to use:
4 - 15' throw @ 30 psi, rainbird sprayheads (half-pattern) at 1.85 GPM each.
2- 15' throw @ 30 psi, rainbird sprayheads (full pattern) at 3.70 gpm each. All for head to head coverage.
According to my calculations, this comes up to around 22 GPM for the complete zone (6 heads x each respective gpm per sprayer). This sounds like a high GPM requirement to me! Could someone possibly advise me if this is the best, efficient setup for this zone and help me size the correct well pump? I'd really appreciate it. [
