    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.

    troubleshooting by replacement is a path many choose to follow but is it the correct path? lack of volume, pressure or both are too easy to determine.

    poor richard says:
    someone backed over the top most head next to the drive (withn the turf, not that corner head in the bed)

    broken tee
    +1 for swing joints

    Im just guessing though :) Please let us know what the issue ends up being.

  7. What kind of heads you have....rotors fixed sprays, impacts.....


    if fixed sprays,, brand


    nobody mentioned this,on fixed sprays, but the wiper seals do eak, depending on what brand. Got leak ther, never going to have pressure specially if zone is above 80% of capacity.

    They are pop up heads, but they dont rotate, they just spray in one direction (fan pattern). They are rainbird brand.
     
  9. so fixed sprays.....rainbird bran....on the top of the sprinklers, do they look like a a honey comb or are basicly black circle with a white center in the area the stem pops up?

    either way, turn on the water and look at the top of head, a possibility is the seal has failed and is actually leaking. If they are, then there's your reason for lack of pressure.

    Nobody has yet addressed the other two issues the poster mentioned. Standing water anywhere in the turf indicates a problem. A constant wet crack in cement is a problem.
