K-Rain RPS 75i Rotor 4 in. | RPS-75I
Product Overview
System failures during the height of the summer heat can lead to rapid turf stress, scorched landscapes, and frustrated clients. When a standard rotor fails to deliver uniform coverage or the Intelligent Flow Technology is missing from your inventory, you face emergency service calls and potential plant loss. With peak season demand stretching your crews thin, the time to secure your inventory is now. Supply chain fluctuations often occur when demand is highest; however, planning your stock today ensures your projects remain on schedule and your service contracts stay profitable. Reliable equipment in your truck means you can resolve issues on the first visit, preventing the headaches of back-orders and site return trips.
The K-Rain RPS 75i sets itself apart from standard 3/4 inch rotors through its integrated flow control, allowing you to manually adjust the distance and flow rate simultaneously. Unlike lower-grade options that require nozzle changes to manage radius, this rotor enables your crews to fine-tune the spray pattern without sacrificing uniformity. This technical advantage significantly reduces labor time during system startup and zone balancing. By stocking a rotor that handles a wide range of radius requirements through simple adjustment, you reduce the number of individual parts your team needs to carry. This efficiency provides a competitive edge, allowing for faster installations and more precise water management for your clients.

Installation Notes
Installation requires a standard 3/4 inch threaded swing joint or funny pipe assembly to ensure the rotor remains at the proper grade. Use the K-Rain adjustment key to set the arc before or after the rotor is under pressure. It is recommended to flush the lateral lines thoroughly before installing the nozzle to prevent debris from clogging the internal filter. Always comply with local plumbing codes regarding backflow prevention and pressure regulation to ensure the long-term performance of the sprinkler head.
