Question
We have a JH Irrigation System at our 8-year old home.  Each station set to run 10-mins. This morning, sprinkler heads pop-up spray for 5-seconds and go back down.  This continues throughout the cycle and repeats at the next station.  No station runs with heads staying up completely for the 10-minute cycle.  Any suggestions? Thanks!

Answer
Hi Terry,
The system pop up for about 5 seconds and consumes all the 10 minutes without watering?
Sounds like a water problem.

Can you give more details about your system. What's the water source, city, lake, well?
Do you have a pump?, a backflow prevented?.
Please give as much details as you can, so I can help you.

Thanks
Guillermo
