Check out the LittleValve IFR Benefits:

  • No more overspraying onto sidewalks, streets and buildings - Dial in your distance.

  • Use only 15 foot 'Spray' nozzles eliminating all 5', 8', 10' and 12' nozzles. IFRs reduce the radius of 15' nozzles down to 6 feet with bigger, fatter, heavier droplets that resist wind drift and penetrate the ground better.

  • Quadruples the range of Toro's Precision Rotating Nozzle by reducing radius down to 18 inches. Triples the range of Rain Bird's 17-24 rotary nozzle by reducing its radius to 5'.  Makes obsolete Rain Bird's two other sizes of rotary nozzles.

  • Makes Toro and Rain Bird's Flat spray nozzles world's best Micro-Sprays down to 2'. 

  • Bring side strips down to 3' - 4' left/right. Turn Hunter's SS530 side strip nozzle into a micro-spray.  Almost every 'adjustable' nozzle can be made into a micro-spray.

  • Never touch the little screw on top of spray or rotating nozzles.

  • Easily controls the distance range of any above-grade gear-driven rotor all the way down to 'OFF' without touching the diffusion screw.

  • Eliminate pressure regulation and pressure-compensating devices - they are never needed.  LittleValves override ALL high pressure eliminating wasteful misting and fogging with its huge water losses.

  • Now you can have above-grade 'Drip' systems via our new Micro-Stream Caps with pin-point watering.  See "Micro Stream Caps" tab to see our full line of above-grade, pin-point watering products that replace troublesome drip tubing.

  • And best of all, with individual On/Off control at each sprinkler, you save hours of time and labor by eliminating all trips back and forth to the valve or controller just to service clogged sprinklers or exchange nozzles.

Simple & Easy Sprinkler Head Maintenance 

Eliminate trips back and forth to valve and controller
just to service a clogged sprinkler or change-out a nozzle

Originally developed to make sprinkler maintenance easier and faster. Pictured below is a pop-up sprinkler being flushed by just one person whle the valve is fully open without helpers and without going back and forth to the controller or valve.

During the process you see in the photo below, the pop-up stem will never retract until you shut off water to the system.

After flushing, shut off flow exiting the extended pop-up stem by turning the little key clockwise.  Insert filter, re-attach the nozzle. Then turn key counter-clockwise until water exits nozzle at the precise distance you want.  Pull out the key and you're done.

Flushing CrossYou have full On/Off control at every sprinkler regardless of what LittleValve
IFR part you have in your landscape - pop-ups or above-grade shrub adapters.
