                                     Hunter® Industries.  I-20-04-NCV     (no check valve)
                                                                 Sprinkler Head With Flow Stop. 3/4" Inlet 4" Pop-Up

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 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.



This patented feature returns the turret to the original arc regardless of where it is turned. This ensures vandal protection in any environment.

Patented non-reversing 360 for part- and full-circle in one model, from 50 to 360 degrees.
