The K-Rain PROPlus 5-inch adjustable arc rotor (SKU 11003CV) is a gear-driven, heavy-duty pop-up sprinkler head built for medium to large landscapes. This model includes a built-in check valve to prevent low-head drainage and a 5" riser that improves performance in taller turf and shrub areas.

Reliable arc and memory: Easy Arc Set allows 40°–360° adjustment; the patented Arc Memory Clutch returns the rotor to its preset position if the turret is forced past its stop.
Nozzle package: Includes numerically coded interchangeable nozzles (standard and low-angle) with a pre-installed #2.5 nozzle for flexible system design.
Key specifications: 3/4" female NPT inlet, flow range 0.5–10.0 GPM, pressure rating 20–70 PSI, precipitation rate 0.06–0.50 in/hr depending on spacing and nozzle.
Performance: Radius 22'–50' (nozzle dependent); recommended spacing 28'–44' for even coverage and efficient water distribution.
Durable construction: Rubber cover seals out dirt, ratcheting riser eases left-start adjustment, and the patented reversing mechanism delivers long-term reliability.
Installation notes: Designed to replace standard rotors on 3/4" female NPT inlets; the built-in check valve prevents low-head drainage when installed above the lowest head in the zone.
