Abstract
An irrigation system including a diverter line is provided. The system includes drip irrigation lines, T-junctions interleaved between adjacent drip irrigation lines, 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. The controllable valve is operable to permit fluid flow in only the forward direction and to prevent the fluid flow.
