Abstract:
1. A drip irrigation system including a diverter line, the system comprising: a plurality of drip irrigation lines arranged aside the diverter line; a plurality of T-junctions interleaved between adjacent ones of the plurality of drip irrigation lines, each 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 plurality of drip irrigation lines and a third leg configured to be coupled to an upstream end of a downstream one of the plurality of drip irrigation lines; a check valve operably disposable between the second leg and the downstream end of the upstream one of the plurality of drip irrigation lines to permit fluid flow in only a forward direction from the downstream end of the upstream one of the plurality of drip irrigation lines to the first, second and third legs; and a controllable valve operably disposable between the third leg and the upstream end of the downstream one of the plurality of drip irrigation lines, the controllable valve being operable 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.
