Designing my own System


I am designing my own system and have a few questions.

City Water
Water pressure is 65 ppm
Design Pressure 55 PPM
Design 11GPM I have a 1in PEX main line and was told to only do the GPM for that rated pipe.

I plan on using PR5000 with PRS rotors and want to put 5 or 6 on one valve. Will be using the 1.5 or 2.0 head at 28ft.
Will this work?

How many sprays can you have on one valve?
I was hoping to have 8 in a long irregular shaped section of my yard. I will be purchasing VAS and HVAS rainbird sprayers, ranging from 4 ft to 10 ft spray range heads.

I plan on having 4 drip irrigation zones. I was thinking of installing a filter on the main line in the house close to the Water Meter. I would rather clean one filter then 4 and the valve box will be over crowded if i have one for each valves
Is this Ok?

I will have two valve manifolds on either side of my house, that are feed from two separate exit points from the house. (I have a pool and can't get mainline around it). One side of the house will be drip irrigation and a small lawn.

In this section do i have to put 100DVF valves in a box or can i put the manifold on the wall?

Last Question.
How do you determine how many valves can go in a valve box?

I have replaced an irrigation system in my old house but I followed the previous design. This is my first time designing my own.
