Optional Components
Irrigation Controller
To maximize the efficiency of your subsurface drip system, choose a
controller which allows multiple start times. For small, one-valve
installations, battery-operated timers may be mounted directly onto
the supply line. For larger, multi-valve installations, an irrigation
controller may be rewired. Typical controllers have 6 to 12 stations.
Some controllers have a battery backup in the event of a power failure.
Choose a controller that can expand with your landscape needs.
Fertilizer Injector
One of the main advantages of subsurface drip irrigation is that
fertilizers and other chemicals can be applied safely through the
system. Injectors must be installed downstream of the backflow
prevention device and upstream of the filter. An injector can be used
to keep driplines clean by injecting cleaning solutions.
Water Meter
Water meters can be used to diagnose problems as well as to schedule
irrigation times.
Soil Moisture Sensor
Soil moisture sensors override the timer if there is too little or too much
water in the soil. There is no need to adjust watering schedules to
climate changes. Moisture sensors can be used to control individual
valves or to override the whole irrigation controller. Sensors should be
installed at the driest areas in the field.
