    I have a lady whose system was installed using Hunter PS heads. It has been extremely hot and dry here and you can tell exactly where the heads are not spraying head to head. I adjusted them some today but I have a question for someone more familiar with these heads.
    The heads in the center of the lawn were turned down considerably so I opened these on up and they seem to be spraying head to head now. The heads along the curb and edge of the lawn are closed down to spray the 180 but when doing this do not reach the heads out in the center of the yard. If you open them on up they will hit the center heads but are also spraying a 360.
    Is there a way to flow more water on the 180's without opening them up to a 360? You can adjust them to spray a 360 with not much flow or open them up for what looks like twice as much flow while still making a 360.

    These look like a good idea but are a nightmare to adjust! Never messed with these heads before though.

    Check the flat head screw located in the center of the head. Back it all of the way out for max flow.
    If that doesn't work, you could nozzle up provided enough volume exists in that section.
    Check the number on the top of the spray nozzle and let us know what it is.

    Use a Hunter PGP wrench on the center hex screw to adjust flow.

    I messed with the hex screw some in and out but just seemed to open the nozzle up to a 360 or close it off. I will look at them again and make sure on that part though. I thought about changing nozzles, but the ps is all one unit. No way to change nozzles!

    You have to hold the nozzle top still, when you adjust the hex screw. Hunter has a how-to page on their website.

    I went and read the how to. I will try that and see what happens!

    They suck, swap them out with a RB 1800.

    My next thought as well. If they work and have no problem, leave it. If you can't figure it out, swap it out. 1804 or 1806

    1812 for slopes in turf and always in plantings.
