i met with my foremans parents this weekend to help design them a landscape plan, and his dad was talking about how he designed and installed this system nearly 30 years ago.

All I could think of was, oh geez. I asked him for a site plan, and he had a copy of the one with the irrigation drawing on it. I was amazed. Precip rates, flow calulations, friction loss, everything.

Better design and process than most of the irrigators that I see.\

He had a little book from Rainbird called "How to design your own sprinkler system:

Although, he calls a zone a "circuit"

How did they get a gpm number with four significant digits?

Looks like he was pretty thorough. What heads were those? And what valves?

"Circuit" is a old term, bet it's got WM or Imperial valves.

Added up values from old RB nozzle chart, I bet.
