Four types of irrigaiton sensors - ANS-Freeze
Rain
Wind
Soil moisture
A pass connection is any real or capability connection between a potable water supply and...? -
ANS-Any source that has the possibility to introduce polluted or infected water returned into the
potable water this is imparting it
A tool utilized in electric troubleshooting is referred to as..? - ANS-A virtual multi meter
A device used to turn a short coupler valve on and rancid is? - ANS-Quick coupler key
A drawing of an set up irrigation system showing fundamental components is? - ANS-Called a
document drawing
A photo representation of precipitation is called...? - ANS-A desogram
A measuring tool that has measurements as a given number of feet in line with inch is? -
ANS-Engineer scale
A technique of retaining a consistent discharge strain regardless of inlet strain is referred to as?
- ANS-Pressure compensating
A motorized tool which creates, or boosts strain is? - ANS-A pump
A swing joint is used to? - ANS-To save you damage to the head
A timing tool which alerts the automated valves to open or near is called a...? - ANS-Controller,
clock, timer
A valve that permits water to travel in simplest one path is referred to as? - ANS-Check valve
Absorption Rate - ANS-The pace at which water can penetrate or infiltrate the soil
Absorption price is defined as? - ANS-Rate at which soil will accept water
Actual Head Pressure - ANS-The operating stress measured at the base of a sprinkler head.
, Actual head pressure components - ANS-(Static strain) - (Total pressure lost) = Actual head
pressure
air gap - ANS-an approved Air gap is the unobstructed vertical distance via loose surroundings
between the lowest point of a water supply outlet and the flood level rim of the fixture or
assembly into which the opening discharges. Physical seperation must be at the least twice the
diameter of the water deliver outlet however by no means much less than 1"
An AVB needs to be mounted...? - ANS-6" better than the best head
Will forestall backsiphonage
An electric valve is likewise called? - ANS-Automatic manipulate valve
Application Rate (Precipitation fee) - ANS-Rate at which water is implemented through sprinkler
heads in a certain sample.
Arc - ANS-Degrees of insurance of a sprinkler from one facet of a pattern to the alternative
Atmospheric Vacuum Breaker (AVB) - ANS-Backflow prevention device that permits air into the
piping machine, with the usage of a go with the flow that moves up and down, to prevent
backsiphonage.
Cannot be under constant strain for extra than 12 hours in one 24 hour window.
A minimal of 6" higher than all down stream piping.
A separate AVB ought to be established on the discharge aspect of each manipulate valve,
among the valve and all emission gadgets.
Automatic manage valve - ANS-An electric or hydraulic far flung control valve in a sprinkler
system which is activated by means of an automated controller
Backflow - ANS-An unwanted reversal of the drift of water in a piping system which can
doubtlessly permit non-potable water to pollute or contaminate the potable water supply.
Backflow prevention devices - ANS-Air Gap
Atmospheric Vacuum Breaker (AVB)
Pressure Vacuum Breaker (PVB)
Double Check Valve Assembly (DCA)
Reduced Pressure Prevention Device (RP)
Backflow prevention methods - ANS-Any authorised device which prevents an undesirable
reversal of drift of water via the creation of air, test valves, or a aggregate of both.
Backpressure - ANS-Any condition that might create pressure in the discharge facet of the
piping device that is greater than that of the deliver aspect of the gadget.
