Ok ive got my design diagram almost completed, ive submitted it to get a permit but i didnt figure the design operating pressure... I was under the impression since im not a proffessional it wasnt a requirement but i was incorrect about that. So ive got most of my components (which i ordered from this website's store) but zero of my main and lateral lines which will be 1" mains and what ever is required after that. my valves are 1" hunter valves and a febco 1" PVB, and im using rainbird US-400 4...
