View Full Version : Hunter PS heads

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

1806

1812 for slopes in turf and always in plantings.

looks like a lot of Rainbird fans? I agree they suck and the h/o already told me if they are not going to work right she will have me replace them with regular popups.

1812 always in plantings.

Is it okay to hard-pipe into the bottom of them about 12 inches above grade so they'll clear when the shrubs get taller?

Is it okay to hard-pipe into the bottom of them about 12 inches above grade so they'll clear when the shrubs get taller? Or is it better to side-pipe them with an extra-long piece of funny pipe, which you can then cable-tie to a piece of rebar to get the desired height?

As a Leary aficionado let me try and answer. In beds he uses 1812s at 5'spacing with WM brass flat fulls. Never need to raise with that kind of spacing.

Have ya taken one apart and seen if the screen was clogged? Personaly between 10-15 ft , I think its a far superior spray head then an RB.

This is a screaming upgrade opportunity. I'd go 1804 sams with brass nozzles.

Not with careful Lincoln moisture meter checking for run times.

Yes, if one cares little for DU over time.

If I spaced them any closer, there'd be no room for plants.:rolleyes:

Who wants plants when you have shiny copper risers to look at?

Copper? I was thinking purple reclaimed PVC, give a little color when the plants aren't blooming.

Beware on the older versions if you crank the screw down too far, it will drive right through the top. Then you end up with a nice geyser.:rolleyes:
