The first part of the Drip Irrigation System is the Backflow Preventer. The backflow preventer (see picture to the right) makes sure that dirty water does not flow back into the PVC pipes and contaminate the water system.
The picture to the right shows the Backflow Preventer connected to the Y-hose adapter. I need one Backflow Preventer for each Drip Irrigation system.
The timer is used to turn on the Drip Irrigation System at the correct time. It controls the duration, the frequency (how many times during the day), and when to turn on the Drip Irrigation System.
The timer is battery operated using a 9-volt battery. I change the battery once a year.
However, since the Drip Irrigation system is now connected to the my Sprinkler system, I have to also turn on the Sprinkler system in order for water to flow.
The picture to the right shows the Filter and the Pressure Regulator.
The Filter prevents any debris in the water system from getting into the Drip Irrigation system and clogging up the drip emitters.
The Pressure Regulator makes sure the water pressure is low enough so that water does not come out too fast from the drip emitters.
The picture to the right shows the pieces of the Drip Irrigation system connected to together. There is one set for each Drip Irrigation zone.
I set the timers so that the two Drip Irrigation zones run at different times. Otherwise, the water pressure is too low, as the water come from the PVC pipes would have to be divided in half.
The last part of the Drip Irrigation system is the Drip Tubing adapter. This connects the Drip Tubing to the Pressure Regulator.
