Hunter I-20 Adjustable Rotor 4 in. Riser with Check Valve

With 34 nozzle choices, a 17 ft. to 46 ft. radius, and 6 body choices, the I-20 is an indispensable rotor. Whether you’ve got a small area, sandy soil, or a mix of shrubs and grass, the I-20 is ready to water with efficiency and reliability. Recent improvements include automatic arc return, non-reversing 360, from 50 to 360 degrees, and a non-strippable, vandal-proof drive mechanism that prevents gear stripping and saves repair costs. Adding FloStop control, easy through-the-top arc adjustment, and a standard drain-check valve all equate to a rotor that stands second-to-none in its class.

Flostop control: FloStop closes the flow of water from individual sprinkler heads while the system is running. This is ideal for changing nozzles or turning off specific heads during maintenance and construction
