In-stem Flow Regulation (IFR) - the most significant change to sprinklers in 50 years:
Providing On-Off control at each sprinkler head
Check out all these LittleValve Benefits:
- No more overspraying onto adjacent sidewalks, streets and buildings - Dial in your distance.
- Use only 15 foot 'Spray' nozzles and eliminate all 5', 8', 10' and 12' nozzles. IFRs can 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 taking radius down to 18 inches. Triples the range of Rain Bird's 17-24 rotary nozzle by taking its radius down to 5 feet.
- Toro and Rain Bird's Flat' spray nozzles become the world's best Micro-Sprays down to 2 feet.
- Bring side strips down to 3' - 4' left/right. Turn Hunter's SS530 side strip nozzle into a micro-spray, as well.
- Just about every 'adjustable' nozzle can be turned 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.
- Eliminate wasteful misting/fogging with its huge water loss.
- Now you can have above-grade 'Drip' systems with our new Micro-stream drip caps.

- 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.
Originally developed to make sprinkler maintenance easier and faster. Pictured below is a pop-up sprinkler being flushed by just one person 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 the 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 the key counter-clockwise until desired amount of water exits nozzle to the precise distance you want. Pull out the key and you're done.
CAUTION: You WILL get spoiled using LittleValve parts.
In commercial installations, PRNs, PSNs, Little Tuffys and LittleValve parts are
all rebatable under the Southern California Metropolitan Water District program.
