More efficient side yard - 45x15 >>

    I have a side yard that is 45x15. Currently have 3 RP5000 heads evenly spaced down the side. I have the nozzles pretty much closed so it doesn’t over spray the area. Its working but doesn’t seem very efficient.

    Is there a different setup I can use with the RP5000’s or should I swap those out for some spray heads?

    Olden days might see three square-pattern popup sprays, but better to use eight standard popup sprays in head-to-head, so Kiril won't yell at you :)

    Yeah.. thats what I have on the ot her side. Its 45x7 though. 7 or 8 sprays.

    Anything I can do on this side without adding heads?

    Im expecting to get yelled at. I do everytime I post post in this forum :)

    If you have to stick with three heads I'd try WM's LA nozzles with adapters for popups. Use the 20s. http://www.weathermatic.com/index.cfm?page=100 Series Shrub Nozzles

    Put them on 6" popups. Hopefully you have enough slope to get some runoff to the edge.

    Or you could try the LA version of these but its 15 degrees versus 10 degrees. Also in 20. If that doesn't quite do it then use the 24s. I'm banking on a little flood irrigation to reach the outer edge. These put out massive quantities of water.

    Yeah I have a little slope so that would work. Instead of WM brass ones, could I use the RP rotor nozzels. I have them in a couple other spots and they work great.

    A couple 2/3rd nozzels and a 180 for the the center. The throw is 13-18 so that would be about perfect dialed in.

    The only problem I see with either setup is a I have one more RP5000 on this zone. If I went to any type of popup spray setup the precipitation rates are going to be pretty off I would think.

    That cat stayed in the bag a bit too long, lol. Your closest match is going to be MP rotators then most likely. And actually, you should be able to switch them all out to MPs and not keep the random rotor (if the 4th is dialed down a bit too), as the mp has versatility ranging from 10-30 feet.

    As for the effectiveness of your setup, it has to overspray the top edge in order to avoid complete blank spots anyway so it has weaknesses to begin with. That being said, if you are looking for water efficiency with your current diagram the mp is much more efficient than a dialed down rotor.

    you can always re-nozzle the remaining rotor head to match precip rates

    Suck it up and add two more sprinklers giving you triangular spacing.

    If I need to swap the heads anyway and thats the right way to do it, then I guess that's what ill do. Are the other ways just not good setups?

    assuming like this...

    Eight heads in square spacing would be textbook perfection.
