Head Placement

So I have a question on head placement... I have 45psi static pressure,
3/4 main service line, tapped off main with all 1" pipe/backflow

I have one zone that has minimal grade change with only a short distance from the valve. The lawn is a 40'x32'.

My though was to just use (4) Rainbird 5000 Series in the corners spraying quarter circles.

If I can get a 32' spray I should have head to head coverage on way and almost head to head the opposite way??

Thanks for your help!!!

You could always use a swing joint under each head, and place them slightly off vertical, so each head coverage pattern becomes a partial ellipse, instead of a part circle.

With 45 psi and only running 4 heads, there is no need to go with 1" lines and valves. Just go all 3/4", and save some coin. YOu will still have the option of changin the nozzles if you need more distance.
