PAPER 2026 COMPLETE QUESTIONS
AND CORRECT ANSWERS GRADED
A+
◉ New Installation.
Answer: An irrigation system installed at a location where one did not
previously exist.
◉ Major Maintenance.
Answer: Alteration, repair, or service that involves opening the mainline
to the atmosphere. Includes mainline repair, valves, and replacing the
diaphragm.
◉ Completion of irrigation system.
Answer: All standards are met and the irrigator is satisfied.
◉ Absorption Rate -.
Answer: the rate at which soil absorbs water. This is essential for
determining the amount of water needed and the time between
irrigations.
◉ Arc.
,Answer: The surface area of a landscape bed the head will provide water
(half, full, 90, or 45)
◉ As built plans.
Answer: A corrected or redrawn plan, showing location of all major
components.
◉ Actual Head Pressure.
Answer: The operation pressure at the base of a sprinkler head.
◉ Bubbler.
Answer: A low pressure irrigation emitter that releases water at or near
ground level. It is commonly used for deep watering of trees and shrubs.
◉ Booster Pump.
Answer: Increases operating pressure
◉ Check Valve.
Answer: A valve that allows water to flow in only one direction,
preventing back flow and ensuring even water distribution across zones.
◉ Controller.
Answer: A device that schedules and controls irrigation zones and
runtimes automatically, based on a set program.
,◉ Cycle.
Answer: A complete watering sequence in an irrigation system, from
start to finish of each zone.
◉ Direct burial wire.
Answer: Listed UL, UF. Any wire approved for direct underground
burial without conduit.
◉ Design Pressure.
Answer: pressure required for an emission device to work correctly.
◉ Drip Irrigation.
Answer: An irrigation method where water is delivered slowly and
directly to the base of plants through emitters, reducing water waste and
evaporation.
◉ Emission Device.
Answer: Any device that is contained within an irrigation system that is
used to apply water.
◉ Evapotranspiration (ET).
Answer: The total water loss from soil evaporation and plant
Transpiration. used to calculate the irrigation needs of plants.
◉ Flow Control Valve.
, Answer: A valve that can be mechanically adjusted to restrict water
flow.
◉ Flow rate..
Answer: The amount of water moving through the system over time,
often measured in gallons per minute (GPM) or Liters per hour (LPH)
◉ Head to Head coverage.
Answer: A sprinkler design method that ensures overlapping spray
patterns for even water distribution without dry spots.
◉ Hydrozone.
Answer: Grouping plants with similar water needs together in an
irrigation zone to optimize water use.
◉ Irrigation Zone.
Answer: A specific section of an irrigation system with similar watering
needs, controlled as a group from the controller.
◉ Main Line.
Answer: The primary pipe that delivers water from the source to the
irrigation system.
◉ Mirco-Irrigation.
