Irrigation System Components

 

  drop Water Supply: The water supply for an automated irrigation system can vary and may come from a lake, pond or a local water company.  Water Flow Productions helps determine which water source the most efficient for any given situation.
  drop Spray Heads or Bubblers: Spray heads are used in planting beds and in small lawn areas. They provide a spray or mist over the turf or plants.  Spray heads (sometimes called mist heads) are placed 5 to 15 feet apart in a square or triangular pattern.

Spray head sprinklers are actually composed of two parts:  a pop-up head and a nozzle. Pop-up heads come in various heights ranging from 4 inches (good for lawn and ground cover areas) to 12 inches (ideal for taller shrubbery and plantings).  The nozzle part of the sprinkler allows for various patterns and different spray distances.  Water Flow Productions uses "matched precipitation rate" nozzles which ensure a uniform amount of water will be applied over a given area.  Pop-ups will pop up to spray and retract when not in use.

Bubbler nozzles can be fitted on pop-up sprinkler heads and are used in tight areas and near roses allowing the water to run out the head slowly without spraying.

Rotary or impact sprinklers: Used in large open lawn and planting beds.  Rotor type heads provide a single stream or multiple streams of water covering a distance from 20' to 65'.  Rotor sprinklers cover a larger area than mist heads but apply water slowly reducing runoff.  Modern heads can be adjusted from full circle to part circle and allow the use of different nozzles for pattern and distance adjustments.

Rotor heads are also offered in different pop-up heights and will retract when the water is off.  Water Flow Productions installs all heads on a swing-pipe design which allows the heads to be run over by lawn mowers or tractors without breaking off.

The impact head is an older type head but is still used in many landscapes and garden designs today.  Although these heads are available in a pop-up model for lawns, they are often used on stand pipes for very large planting areas.  Pop-up impact heads need to be maintained to keep grass and straw from stopping the rocker arm that rotates the head around.

  drop Control Valves: These valves are controlled by the irrigation controller. They receive signals to open and close from a low voltage wire buried from the controller to the valve.  Each valve controls a group of sprinklers sometimes referred to as a zone or a section.  The number of valves in a landscape is determined by water availability, plant material, and site demands.    Water Flow Productions uses only electric control valves equipped with a flow control feature to allow fine adjustments in the amount of water reaching the heads.  If the water pressure is too great, the water spray will mist or fog and be blown away from the area.  Electric valves are located in an in-ground  valve box which allows easy servicing of the valve and adjustment of the flow control as necessary.
  drop Controllers: Irrigation controllers (timers) are the brains of an irrigation system.  They control the valves that control the heads. Controllers store the program or water schedule.  They are available as an electronic model or an electromechanical variety.  The electronic or solid state controller offers more features such as time, date and specific watering programs which can be adjusted to meet individual landscaping needs.  These controllers can turn on a pump station or wired to turn off depending on recent rainfall.

Water Flow Productions can assist with various types of controllers ranging from electromechanical models with buttons and displays to units with knobs and gears.

The best way to get the most out of today's electronic controllers is to understand the demands of individual landscapes and the possibilities provided by each irrigation system.
