First, check the controller to make sure that it is working properly. Some clocks have a battery back up, so it may appear that the controller is on. If a controller is working on a battery back up, it will not activate the system. Plug in a hair dryer or similar appliance to check the power to the outlet. Second, check to make sure the water supply to the irrigation system has not been shut down at any point. Lastly if the water is turned on to the system, check your electrical connections to your valves.
First, check the clock program to make sure it hasn't been changed. Next turn the clock off, using the dial, don't unplug the clock; it may lose its program. If the system won't shut off from the clock, you will need to shut the water supply, to the entire system off. Valve to that zone needs to be repaired.
If the leak is constant (leaking when the system is not in actual operation) the system should be shut off at the point of connection. If the leak is not constant, (only leaks when the system is in operation) turn the run time off on that particular zone. If any leak is found, call Accent Sprinkler Repair, and we will respond within 24 hours and schedule your repair.
If it's the whole system, chances are the shut off valve has been turned down. Locate the main water valve to the sprinkler system and turn valve counter-clockwise, until it stops. If it is one zone with low pressure, there could be three reasons:
- There is a break in the PVC line or a sprinkler has been knocked off (look for excess standing water).
- The irrigation valve has malfunctioned and is not allowing water to flow freely. This is commonly caused by faulty diaphragm.
- The flow control to the irrigation valve has been turned down too far.
You will first need to locate the valve that is not working. There could be three reasons for your problem:
- Check wire connections.
- In most cases the valve is working, but the valve diaphragm has shut down, not allowing the water to flow through. If the valve is receiving power from the controller, you should hear a slight hum, coming from the valve. You will need to replace the diaphragm.
- If the controller is flashing "fault" or shuts down, every time you turn a specific zone on, you could have an electrical short. You will need to contact Accent Sprinkler Repair Co., and we will respond within 24 hours and schedule your repair.
The problem lies with the time of the system. Multiple start times have probably been set. Most controllers have an A, B, & C program with multiple start up times. Check the program for the system and just leave one of the start times turned on. This is the simpler way for troubleshooting this problem. Another cause could be if the controller loses power and does not have a proper back up battery, the controller will reset the time to midnight and each zone will run for ten minutes.
