FAQ

FAQ General overview message
  • What is Misting?
    In its simplest form, misting systems incorporate a spray nozzle designed to produce water droplets smaller than the diameter of a human hair, even as small as 5 millionths of a meter. When water droplets this small hit the surrounding air they "flash evaporate", reducing the surrounding temperature as much as 35 degrees fahrenheit. This scientific principle, known as thermal dynamics, was the basis for the development of Arizona Mist.
  • I live in a humid climate. Will a misting system work for me?
    Yes. The evaporative cooling concept will work ANY time you are able to achieve evaporation (See "How does mist work?"). The more complete the evaporation, the more effective the system will work. For areas with humidity above 80%, temperature reductions will be as high as 10 degrees. For humidity levels between 40% and 80%, temperature reductions will be as high as 20 degrees. Below 40% humidity, the temperature reductions may be as much as 35 degrees.
  • What should I do if misting nozzles plug up?
    Because of the extremely small size of the nozzle opening (15 thousands of an inch!), some of the misting nozzles may eventually plug up. If this should occur, the nozzle should be removed and soaked in the Arizona Mist Nozzle Cleaner (See the bottle label for specific cleaning instructions). If the nozzle is not completely plugged, but simply sprays improperly, the entire mist line can be flushed with the nozzle cleaner for a preventative nozzle cleaning. The nozzle cleaner is safe for consumption, non-toxic and completely biodegradable. See the cleaner label for technical information.
  • Why are one or more of my sprinkler heads weeping or running continuously?
    This is generally because of a ruptured or torn diaphragm in one or more of the control valves. First, be sure that the valve is not installed backwards. Next, check that the solenoid plunger is not stuck or missing. To do this, remove the solenoid and check for debris or a missing plunger. If everything looks functional, remove the cover assembly and check the diaphragm and lower valve body diaphragm seat for chips, fractures, or debris. If the diaphragm is torn, ruptured, or has a tiny pin hole, replace it with the appropraite part. If there is a chip or fracture in the lower valve body, replace the valve. For additional help, refer to the troubleshooting section of the specific valve model number.  Helpful videos demonstrating all these steps can be found here.
  • How do I adjust the arc on my gear drive sprinklers?
    To Increase the Arc Insert the plastic end of the Orbit key into the pattern adjustment socket. While holding the nozzle turret at the right stop, turn the key clockwise. Each full turn of the key increase the arc 90 degrees. Adjust to any arc between 40 & 360 degrees. When the maximum arc (360) is reach, the key will stop turning or there will be a ratcheting noise. To Decrease the Arc Insert the plastic end of the Orbit key into the pattern adjustment socket. While holding the nozzle turret at the right stop, turn the key counterclockwise. Each full turn of the key decreases the arc 90 degrees. Adjust to any arc between 40 and 360 degrees. When the minimum arc (40) is reached, the key will stop turning or there will be a ratcheting noise.
  • What sprinkler heads do you recommend I use?
    For medium sized areas of your property, we recommend that you use four inch pop-up heads to ensure that the heads clear the top of your grass when in the "up" position. For large areas of your property, we recommend the large gear drive heads since they are more efficient and easier to use. For shrubs and flowerbeds, we recommend the shrub heads or mushroom bubbler because it requires less water flow to run.
  • How do I replace a Orbit product under warranty?
    Orbit® Irrigation Products, Inc., (hereinafter “Orbit®”) warrants to its customers that its products will be free from defects in material and workmanship for a period of one year from the date of purchase, unless otherwise stated on the product packaging (proof of purchase required). During the warranty period, Orbit®, will replace, free of charge, the part or parts found to be defective under reasonable use and service, as determined solely by Orbit®. Orbit® reserves the right to inspect the defective part prior to replacement. Liability under this warranty is limited to the replacement or repair of defective parts. This warranty is exclusive and is in lieu of all other warranties expressed or implied, including, but not limited to warranties for fitness, for use or merchantability. No agent or representative has authority to waive or alter this warranty in any way.

  • My timer runs continuously or repeats an additional watering cycle.
    There are overlapping start times programmed. Clear all start times and then enter only one start time. If you would like to water more than once a day, enter the next start time for later in the day. A start time is the initial time of day when the timer will begin to water. Each station or zone will then water in sequence according to its chosen duration. Multiple start times allow you to water all stations more than once in the same watering day.

  • What is the difference between PVC and POLY pipe?
    PVC pipe is stiff, white plastic pipe. It is strong but does not bend (or else it will break). POLY pipe is also durable, but not as thick as PVC. It can be bent around corners without the use of fittings. POLY comes in spools of 50 or 100 feet. PVC comes in lengths which can be difficult to transport.
  • When programming my controller, may I enter a start time for each station or zone to water at different times during the same watering day?
    A start time is the initial time of day when the timer will begin to water. Each station or zone will then water in sequence according to its chosen duration. Multiple start times allow you to water all stations more than once in the same watering day.
  • I need help programming my timer.
    Programming instructions are included with each timer. These instructions are available for each timer in the Product Manual section. Browse the online catalog to find your timer. 
  • Why does my timer keep blowing fuses or tripping the circuit breaker?
    One or more of the electric control valves has a shorted solenoid, or there is a short in the wiring. If you have a multimeter or volt meter you can check your wiring and solenoids for shorts and continuity. Otherwise, try switching another solenoid from a functioning valve to see if the problem valve will turn on. If so, replace the solenoid. If not, you may have to replace the wiring.
  • What is happening to the timer when the display shows that a zone or station is watering but the valve is not operating?
    Check the transformer for output (24VAC). Push the red power reset button or verify that the fuse is good. Turn on a station manually and check the output at that station (24 VAC). If there is proper voltage, there may be a problem with the wiring or the solenoid on that valve. If the valve has a flow control, be sure it is open all the way. If there is low or no voltage, the timer needs to be replaced.
  • Why does the timer operate manually but does not operate when in "Auto" mode?
    There is an error in programming. Reset the timer and then reprogram.
  • Why does my timer turn on more than one valve or station at a time?
    This is generally a wiring problem between the timer and the valves. To be sure, check the output at the timer and verify that there is voltage only at the station that the display indicates is watering. If so, then electrical current from one valve is transferring to the wires on the other valve causing them both to open. Replace the wiring to the valves.
  • My timer says "No AC" and won't work
    "No AC" means there is no electrical power flowing to the timer.  This could be due to no connection, bad connection or power outage.  While our timers do have battery backups, these are only to keep the timer schedule in case of power outage and are not sufficient to power the timer.  
  • Where can I purchase Orbit products?
    Orbit products are available through most major home and garden outlets as well as most major online retailers.  We are proud to be partners with Amazon, Home Depot, Wal Mart, Lowe's and many other of the leading retailers.
  • How do I become a vendor of Orbit products?
    We truly value our vendors and are honored that you would consider carrying our products.  To discuss the many options available to vendors, please contact our sales support team at 800-488-6156.
  • Why are there so many model numbers
    Orbit creates different model numbers on the same product based on where the product is sold.  Small variations, such as color scheme, might exist, but the design and functionality of the products are the same.
