Sprinkler Trouble!!!

The problem I am having is a loss of pressure to only one zone, every other zone is working perfectly fine. I first thought it was a broken head at the bottom of the driveway because none of the heads were popping up and it was just trickling out of that head, but I dug it up and checked it and nothing was wrong. So I went further and marked all the sprinkler heads with blue flags and checked those also, everything is cleaned and should be in working condition. I don't understand why this zone is not getting any pressure, there are no bubbling spots in the yard that would indicate a broken line, if there was shouldn't water be gushing out of it right?
In one picture I circled 2 things with a red circle. One is the driveway where there is a crack that is wet but its only on the left side and water is not pouring out of it or even running out of it, its just a little damp. The other is a wet spot in the yard, not muddy just a little bit wetter then the rest of the yard. If you step on it with your bare foot water will come between your toes. I want to check a couple other things before dig up the whole yard looking for a broken line.


Any body have any help??? I would greatly appreciate it!!!

Thanks

Do you have flow control and if so have you checked it?

Also, if you're on a meter compare zone to zone. There is no use looking for a leak you don't have.

Dig up the heads, cap them off, turn zone on, see where water comes up.

Friction loss, too many heads on the zone, wiper seals leaking.

The system has been in this house for 10 years and has worked just fine until now so I know that line should work with that many heads. I will replace the wiper seals but it still isnt getting enough water/water pressure, its like something is blocking the line.

No water should ever come in the middle of driveway. I think you have a line break. Cap all the heads and I bet you wil get a lot more out that crack. There is a lot of crushed base under there to absorb which is why you don't have a lot bubbling out.

If so the only way to get to the line would be too cut that sections of the driveway out and then fix the line and lay new concrete, correct?

Manually bleed valve TO ATMOSPHERE to check if valve diaphragm is bad or solenoid discharge port is clogged. If you are sure that valve is opening completely then proceed to cap off heads to locate leak (if needed).

Don't know anout your area but its pretty easy to waterjet under a slab. Trick is getting deep enough under the gravel. Other option would be to run around the house the long way. A lot of new construction will lay lines for future irrigation and lighting wire. Under slab is not uncommon around here.
