Save Water In Your Yard
RAIN GAUGE - measures rainfall and/or output from an irrigation system
Use a rain gauge or small wide-mouth can to determine how long to run your sprinklers. By checking it after each rainfall, you can determine the amount of rain and adjust your irrigation system’s watering time. A rain gauge can also be used to measure how much water your sprinkler delivers in an hour. Only ½ - to ¾-inch of water per irrigation zone is needed for a healthy lawn.
RAIN SENSOR - prevents irrigation system operating during and after rainfall
Use a rain sensor to prevent your irrigation system from running during a rainfall or immediately after a rainfall. Rain causes the sensor to keep the irrigation system turned off during or after sufficient rainfall is measured. Most rain sensors have settings that allow some sort of rain measurement to take place. Settings can usually be adjusted so that a light shower will not effect the system operation. Sensors should be set to shut off the irrigation system when ½- to ¾- inch of rain is received.
Sensors should be mounted high off of the ground in a location that allows the device to collect rainfall without any obstructions from overhangs or trees. Place sensors out of the path of sprinkler spray and never place in full sun or full shade.
Florida law requires any automatic lawn sprinkler system installed after May 1, 1991 to have a rain sensor or switch that will override the irrigation system when adequate rainfall occurs. FAC 40C-2.042(2)(a)(5)
