Residential Rotors Support

Welcome to the residential rotor support section. Below you can identify the rotary sprinkler model you may have and find information on installing, adjusting, maintaining and troubleshooting your rotor.         

 
  • Rotor Installation
    Before installing rotatory sprinklers (rotors), ensure you have a good irrigation design plan and enough pressure for the rotors with good head-to-head coverage. If you are unsure,
  • Identifying Adjustment Sockets
  • SRM Nozzle Installation
    If the top of the screw is below the top of the turret, the screw must be turned counter-clockwise until it is flush with the top before removing the nozzle. If the screw is flush
  • Matched Precipitation Rates
    Precipitation rate is the speed at which water is being applied to a specific area. If you have excessively wet or dry areas, you can change the nozzle in the sprinkler to increase
  • PGP Riser Seal Replacement
    Installing a new riser seal on a PGP rotor will increase the durability and life of service of the rotary sprinkler. Follow these simple step-by-step instructions to replace the
  • Trajectory Charts
    The trajectory and spray height of the water stream leaving a sprinkler nozzle is important information when designing and installing irrigation systems.                  
  • Controlling High Pressure
  • Stainless Steel or Plastic
    The stainless steel option on Hunter rotors offers mutliple benefits, here are a few:Vandal Resistance - Parks and other common ground areas that have heavy foot traffic can
  • Replace Another Brand Rotor
    Yes, if you know the model of the existing manufacturer's sprinkler, you can use our Replacement Charts to find the appropriate Hunter pop-up or rotor that will have a similar flow
  • Pitot Gauge
    The easiest of the rotor pressure gauges to use, the Rotor Pitot Gauge (P/N 280100) has a tube that is placed directly in front of the primary nozzle stream for an
  • Side Rotor Holes
    It's a combination drain hole and flush hole.It's a drain hole because we need to drain the water from below the nozzle turret so it doesn't push up on the nozzle turret in
  • Shutting off Rotor
    There is a blank nozzle available as part of the Low Angle Nozzle Set (Part Number 233200), which can be inserted into the PGP to shut off the flow of water.Remember the riser
  • Capping Off Irrigation Head in Ground
    Capping or removing a sprinkler is done differently depending on whether or not you live in an area that freezes and requires the irrigation system to be winterized. Winterizing
  • G-Type Replacements
    Production of the G-Type rotor was discontinued 14 years ago, though many are still in use today. If a G-Type rotor needs to be replaced, the PGP-ADJ or PGP-Ultra is the current
  • Rotor Stopped Rotating
  • Doesn't Fully Pop-up
    Rotary sprinklers require a certain amount of pressure and flow to operate properly. If the rotor does not receive the pressure it needs to pop up a leaky head will result.Here are
  • Leaking Riser Stem
    Hunter rotors have replaceable riser seals that may wear out over time. Sandy soils, sunken heads, or extremely hot and cold temperatures may also cause a seal to wear out
  • PGP - Installing Drain Check Valve
    If you’re PGP heads are leaking water after the system is shut off and the flow of water reduces over time, your heads are experiencing low head drainage. Low head drainage is
