Hi there,I have question regarding my irrigation project. As in diagram, I need to use to control 5 solenoid valves. Just say, I need to fill up water only into Tank2, which I need to open valve2, valve4, while the other valves are closed. My question is,when the water are passing through the pipe in which solenoid valve1 is connected, the water will accumulate in that pipe. Are there any way to prevent that?Thank you so much.
