Incorporated in 1972, K-Rain® Manufacturing started on the path to becoming one of the largest manufacturers of irrigation rotors, sprays, valves and controllers in the world. We hold over 100 patents specific to the irrigation industry including the three-spring reversing mechanism still used today in most gear driven sprinklers.

We have a full line of commercial and residential lawn sprinkler systems, that include rotors, sprinklers, sprays, valves and irrigation controllers. K-Rain® is continually focused on customer satisfaction for irrigation systems. “We pride ourselves on our engineering roots and continually aim to make it better” - Carl Kah Jr., Founder & CEO

K-Rain® persists in leading the industry globally with new developments in rotor and nozzle engineering. Our RPS™ 75i with Intelligent Flow Technology® is the only rotor of its type to significantly reduce water waste by regulating flow and distance proportionately and simultaneously. The RPS™ Select is another unique rotor with 4 built-in nozzles—select the pattern and select the equivalent nozzle for matched precipitation. And in the past few years, we’ve introduced new items such as blue tooth controllers for use with smart phones and Wi-Fi enabled controllers.
