a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines,
the controllable valve being operable to permit fluid flow in only the forward direction from each leg of the three-way line to an upstream end of a downstream one of the drip irrigation lines and to prevent the fluid flow.
2. The system according to claim 1 , wherein the drip irrigation lines have uniform and/or adjustable lengths.
3. The system according to claim 1 , wherein the drip irrigation lines are disposable on both sides of the diverter line.
4. The system according to claim 3 , wherein multiple T-junctions are disposable at similar axial locations along the diverter line.
5. The system according to claim 1 , wherein the controllable valve of each of the T-junctions comprises a solenoid valve.
6. The system according to claim 5 , wherein each of the solenoid valves are opened to flush the system.
7. The system according to claim 5 , further comprising a control station operably coupled to each of the solenoid valves.
8. The system according to claim 7 , wherein the control station operates the solenoid valves in a closed loop configuration based on sensor feedback.
9. The system according to claim 7 , wherein each of the solenoid valves are configured to acknowledge command receipt and to report that a command was performed.
10. An irrigation system including a diverter line, the system comprising:
drip irrigation lines;
T-junctions interleaved between adjacent drip irrigation lines, each T-junction comprising:
