Texas Landscape Irrigation
Pressure compensating devices help save water because they? - answer Help eliminate
misting or fogging at the sprinkler heads
Landscape Irrigation - answer The art and management of applying water to landscape
in a manner to encourage growth of plant material and support water conservation
Irrigation sensors - answer(Measure rain, wind, soil moisture, and freeze) that save
water and eliminate liability issues concerning ice related accidents during freeing
weather
Pressure Regulation Device - answer Devices which eliminate misting or fogging at the
sprinkler heads, thus achieving better uniformity and saving water
Hydro zoning - answerThe practice of zoning an irrigation system based on similar plant
material with similar watering requirements due to environmental and or geographic
influences including, but not limited to, soil type, slope, site orientation, and solar
radiation
Licensed landscape irrigators - answerResponsibility to educate, promote, support and
practice water conservation in the landscape irrigation industry in order to preserve one
of out most precious resources on earth
Absorption Rate - answerThe speed at which water can penetrate or infiltrate the soil
Actual Head Pressure - answerThe operating pressure measured at the base of a
sprinkler head.
Actual head pressure formula - answer(Static pressure) - (Total pressure lost) = Actual
head pressure
air gap - answeran approved Air gap is the unobstructed vertical distance through free
atmosphere between the lowest point of a water supply outlet and the flood level rim of
the fixture or assembly into which the outlet discharges. Physical seperation must be at
least twice the diameter of the water supply outlet but never less than 1"
Most common air gap? - answerKitchen sink
Application Rate (Precipitation rate) - answerRate at which water is applied by sprinkler
heads in a certain pattern.
For irrigation contractors, water conservation starts with? - answerA great design
, Three methods to evaluate application rate - answerDensogram, Precipitation rate
formulas, Water audit
The proper watering time is early morning because? - answerSprinkler patterns are
generally less distorted from the wind
arc - answerDegrees of coverage of a sprinkler from one side of a pattern to the other
The art and management of applying water to the landscape to encourage the growth of
plant material and support water conservation is? - answerLandscape Irrigation
Atmospheric Vacuum Breaker (AVB) - answerBackflow prevention device that allows air
into the piping system, with the use of a float that moves up and down, to prevent
backsiphonage.
Cannot be under constant pressure for more than 12 hours in one 24 hour window.
A minimum of 6" higher than all down stream piping.
A separate AVB must be installed on the discharge side of each control valve, between
the valve and all emission devices.
Automatic control valve - answerAn electrical or hydraulic remote control valve in a
sprinkler system which is activated by an automatic controller
Backflow - answerAn unwanted reversal of the flow of water in a piping system which
can potentially allow non-potable water to pollute or contaminate the potable water
supply.
Backpressure - answerAny condition that could create pressure in the discharge side of
the piping system that is greater than that of the supply side of the system.
Backsiphonage - answerA form of backflow due to negative or sub-atmospheric
pressure within water system.
Backflow prevention methods - answerAny approved device which prevents an
undesirable reversal of flow of water by the introduction of air, check valves, or a
combination of both.
Backflow prevention devices - answerAir Gap
Atmospheric Vacuum Breaker (AVB)
Pressure Vacuum Breaker (PVB)
Double Check Valve Assembly (DCA)
Reduced Pressure Prevention Device (RP)
Ball Driven Heads - answerRotary sprinkler in which roatation is achieved by a steel ball
which is set into a circular motion by water passing through the head
Pressure compensating devices help save water because they? - answer Help eliminate
misting or fogging at the sprinkler heads
