If you have a water valve in your system, ensure it’s connected to the right socket on the control unit. Check the connections are secure. Hold the water valves with your hand and run manual watering for ten seconds. You should feel and hear the valves click just before the pump turns on. If the valves do not click, they are faulty. If the valves do click, you have a blockage somewhere in the system. In rare cases, the orange submersible pump will get an air lock. Unplugging the hose from the valves while the pump is running will get it working again, and will confirm that water is getting to the valves OK.
