IFRs - The World's Only Water Saving Sprinklers and Parts!!
COMPARING THE COST EFFECTIVENESS OF IN-STEM FLOW REGULATORS (IFR) vs. OTHER WATER CONSERVATION METHODS
The following graph was prepared by the Water Use Efficiency division of the Orange County Municipal Water District (OCMWD) for the District's Water Use Efficiency Master Plan. It compares 30 water conservation technologies, methods and products in use throughout the Metropolitan Water District's Southern California region and likely throughout the entire western United States. Note at the top of the chart, the LittleValve In-Stem Flow Regulator is shown to be the most cost-effective way to save water. An interesting side note is that no. 4 out of 30 costs over double the $ 91.00 it costs IFRs to save an acre foot of water - 325,829 gallons.
Not only do In-Stem Flow Regulators save water, they are the most economical way to save that water.
COMPARISONS vs. THE COMPETITION
PRN/Little Valve Combo
Distance Range: 20 - 28 feet down to 18 inches
Arc range: 45° - 270°
The ultimate in high-efficiency irrigation. No other sprinkler is comparable.
Look below to see the number of female radius nozzles you DON'T need when you have a LittleValve part and 2 female PRNs -
just one adjustable model and a full circle model.
