TEXAS IRRIGATOR LICENSE EXAM WITH ACTUAL EXAM
QUESTIONS AND CORRECT VERIFIED ANSWERS 100% CORRECT
ANSWERS.WITH VERIFIED SOLUTION
Absorption Rate/ Infiltration Rate - ANSWER: The rate (or
speed) at which soil will accept water.
Actual Head Pressure - ANSWER: The operating pressure
measured at the base of a sprinkler head. It must be equal
to or greater than minimum head pressure to function
correctly.
Formula: Static Pressure-Total Pressure Loss
Air Relief Valve - ANSWER: Small device used on some drip
irrigation that allows air into the dripline when the system is
not running which eliminates any vacuum that could result
in debris or contaminants being sucking into the line.
Application Rate/Precipitation Rate - ANSWER: Rate at
which water is applied by sprinkler heads in a certain
pattern. Measure in inches per hours, gallons per hours, or
gallons per day.
Formula: 96.3 X Total GPM/ Total Area
, Water Audit - ANSWER: The most accurate method to
evaluate precipitation rates. You will collect water using
catchment devices.
Arc - ANSWER: The surface area of the landscape to which a
sprinkler head will provide water. Described in degrees or
part of a full circle (360 degrees).
Example: a 90 degree arc would be a quarter circle head, a
180 degree arc would be a half circle head, a 360 degree arc
would be a full circle head.
As-Built Plan - ANSWER: A corrected or redrawn plan
showing the "actual scaled" location of all major
components of the system and other information the
property owner might require. Zone valves are the most
important component to locate.
Atmospheric Vacuum Breaker - ANSWER: A backflow
prevention device that allows air into the piping system,
with the use of a float that moves up and down, to prevent
backsiphonage. This is no longer allowed in Texas.
Backflow - ANSWER: An unwanted reversal of the flow of
water in a piping system which can potentially allow non-
