Sprinkler system hiccup (stutter)

I have 6 zones in my yard. One of the zones' water is coming out of the system as like it is stuttering. I can hear the sprinkler head making noise like an electrical noise like it is disrupted somehow and so the water sprays for 1 second next second it stops and it goes on like that.

What is the reason for this? How do we fix this? It seems like it is an electrical issue?

I don't know a lot about sprinkler systems but I'd think it would be more along the line of an obstruction in the line or insufficient water pressure or volume.

Well it was working fine before and the water pressure has not changed.

I guess an obstruction in the pipe or electrical problem maybe?

Try manually opening the valve on that circuit. If water works the valve needs to be rebuilt or replaced.

Sounds like air in the system, is this a first start up for the year?

Once the air is displaced it should be fine!

How do you open the valve? Where is the valve?

No, it has been like that since I moved to the house 3 years ago

How do you take the air out?

Someplace there should be a box in the ground where the sprinkler valves are. Post a picture of valves and we than can tell you how to turn them on manually. Look for something like this.

If the system had been drained last year and this was first startup then you would get that sputtering sound until all the air was pushed out of the pipes.

So when the zone is on does it make the noise the entire time?

If it's been that way for some time then as noted manually turn the valve on and see if it sounds different.

Let us know!
