Large Lawn Irrigation Design: Heads, Valves, Controller

Proven Components for a 9,000 sq ft Rectangular Layout

Assumptions: ≥55 PSI, ≥15–20 GPM. Use Hunter PGP rotors (20+ year track record) or upgrade to I-20 for larger nozzles. Valves: Irritrol 2400 (reliable, serviceable). Controller: Hunter Pro-C with remote for easy zone checks. Connections: Poly x ½" tees—avoid saddle tees (leak-prone). Ask contractors about these specs.
