1. A method of operating a drip irrigation system, the method comprising:
- providing drip irrigation lines aside a diverter line with T-junctions interleaved between adjacent ones of the drip irrigation lines and each T-junction comprising;
a three-way line coupled to the diverter line;
a check valve operably disposable between the three-way line and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction from a downstream end of an upstream one of the drip irrigation lines to first, second and third legs of the three-way line; and
a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines;
opening each of the controllable valves of each T-junction to permit fluid flow in only the forward direction from the first, second and third legs of the three-way line to an upstream end of a downstream one of the drip irrigation lines; and
closing each of the controllable valves of each T-junction to prevent the fluid flow in only the forward direction from the first, second and third legs of the three-way line to the upstream end of the downstream one of the drip irrigation lines.

Abstract
A method of operating a drip irrigation system is provided and includes providing drip irrigation lines aside a diverter line with T-junctions interleaved between adjacent ones of the drip irrigation lines and each T-junction including a three-way line coupled to the diverter line, a check valve operably disposable between the three-way line and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction and a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines.

13. A method of operating a drip irrigation system, the method comprising:
-
providing drip irrigation lines aside a diverter line with a T-junction interleaved between the drip irrigation lines and the T-junction comprising; a three-way line having a first leg fluidly coupled to the diverter line, a second leg configured to be coupled to a downstream end of an upstream one of the drip irrigation lines and a third leg configured to be coupled to an upstream end of a downstream one of the drip irrigation lines; a check valve operably disposable between the three-way line and a downstream end of an upstream one of the drip irrigation lines to permit fluid flow in only a forward direction; and a controllable valve operably disposable between the three-way line and an upstream end of a downstream one of the drip irrigation lines; and operating the controllable valve in a first mode whereby the controllable valve permits fluid flow in only the forward direction from the first, second and third legs to the upstream end of the downstream one of the plurality of drip irrigation lines and in a second mode whereby the controllable valve prevents the fluid flow.
