Providing solutions in irrigation systems

Troubleshooting by our irrigation specialists

    • Problem: After an irrigation cycle has finished it starts again.
    • Solution: you have set more than 1 x start time on your controller, you only need to set 1 x start time this will activate all the valves in sequence.
    • Problem: The water won't turn off even when you have unplugged the control unit
    • Likely cause: A solenoid valve has failed
    • Solution: The water supply to the sprinkler system needs to be cut off temporarily while the part is replaced; every sprinkler system installation that complies with council regulations has an isolation valve that can turn the sprinkler system off without affecting the water supply to the house, it is generally located near the solenoid valves or your water meter.
    • Problem: Controller has no display
    • Likely cause: It has had a surge
    • Solution: Depending on brand, in some instances you can reset the controller via a reset button and in others they have a fuse that can be replaced, if this doesn’t work your controller has probably been damaged beyond repair due to electrical fusion and needs replacing.
    • Problem: Valve boxes full of water
    • Likely cause: Leak in manifold or from solenoid
    • Solution: Replace
    • Problem: Sprinkler leaking from around the shaft when running
    • Solution: Replace
    • Problem: Sand or dirt washing to surface
    • Likely cause: Broken pipe, blown off pipe or cracked fitting
    • Solution: Repaired or replaced
    • Problem: Have a wet patch in your garden or turf that never dries up?
    • Likely Cause: Leaking solenoid, a solenoid is like a tap and when the diaphragm wears it leaks like a tap washer but the water can only escape through the lowest sprinkler on that line.
    • Solution: Replace solenoid valve, if the system is getting over 5 years old and you have a solenoid valve start leaking it is a good indication that you should probably replace them all.
