1. Spray Head Troubleshooting

Due to spray head problems, you may see the sprinkler system comes on but no water. An inaccurate water pattern is also an indication of faulty spray heads. This is the most common issue in the system, and the most probable reasons are:


Step 1: Controlling excessive water pressure, and you can do this in two ways: use the remote control valve to fix the flow or install a pressure regulator on the valve. 

Step 2: Clean the blockage with a soft bristle brush and remove any grass or twigs. Also, clear the area around the spray nozzle. If there is any hard object that can not be removed, then replace the spray head. 

If you follow the above steps, reset your system if your rain bird test all stations are not working.

Step 3: Check the leaking connection and find if there is debris between the wiper seal and stem. To check it, lightly step down on the stem line; water will pop up taking the debris. If you still see problems, then you need to replace the cap.  

2. Troubleshooting Sprinkler System Valve

The rain bird sprinkler has two-zone valves, and an electric controller regulates these valves. When the valves have issues, it leads to: 

Solution: When Single Zone Is Inactive

Step 1: measure the voltage of the controller using a multimeter. Test the common terminal and zone terminal wires. The standard voltage should be between 24v to 28v. If the voltage is high or low, then you need to replace the entire controller. 

Step 2: check the low-voltage wires that are leading from the controller to the zone valve’s solenoid. Ensure they are intact and connected perfectly. If there is any disconnect or damage, then connect the wires or replace them. 

Step 3: if the valve solenoid is faulty, it causes the above problems. In this case, replace the valve solenoid. 

Step 4: there are chances of a problem with the valve itself. For primary cases, disassembling and cleaning the diaphragm can fix the problem. If it does not work, replace the diaphragm and spring. In some severe conditions, you need to replace the entire valve. 

Solution: When Multiple Zones Are Inactive 

Step 1: Check the transformer voltage supply to the controller. If the reading is under 22 volts, then replace the transformer. 

Step 2: simply use a screwdriver to tighten the screws of the anti-siphon device that is built in the valve. 

Step 3: if there is any leak at the zone valve, it may cause by a damaged and worn-out zone valve. You need to disassemble, clean, and rebuild the valve. If the difficulty is not resolved, then replace it.

Step 4: When Rain Bird sprinkler head won’t rotate, or incorrect flow direction, then it can be caused by the backward valve. Check the valve and fix it. 

3. Rain Bird Controller Troubleshooting

Due to defects of the ESP-Me controller, you will face several problems. For example:


Step 1: if the controller display is blank or frozen, ensure the controller is plugged in and getting enough power. 

Step 2: Check the circuit breaker and reset it. The reason is an electrical surge, it can affect the controller. Unplug the unit and re-plug it after two minutes. If there is damage, you need to replace the surge.
