IrrigationQuestion 25 of 100
A rain sensor or rain shutoff device connected to a controller does what?
a.Increases run time during storms
b.Suspends irrigation when sufficient rainfall is detected
c.Boosts water pressure
d.Measures soil pH
Explanation
A rain sensor interrupts the controller's watering cycle once it detects a set amount of rainfall, preventing irrigation during and shortly after storms. This avoids the waste of watering an already-wet landscape. Many California water agencies require or encourage rain shutoff devices on new systems.
