| Hi,
I have a small area of lawn in my front yard that I need to address in terms of irrigation. I installed a sprinkler system and used "Orbit" sprinklers (a total of 4 sprinklers). I am experiencing 'brown spots' and decided to purchase rain bird 'dual spray heads' (2.5") to address this issue. When I turn on the irrigation system, the sprinklers barely lift and do not spray much water at all (just as if there is not enough water pressure). I put the original Orbit sprinkler heads (2.5") and they spray with no issues except the coverage. What can I do? Any suggestions? Are there other sprinklers like Orbit that are dual-spray? It seems like the springs on the Orbits have a different tension rate. Thanks in advance. |

| I wonder if these rain bird will help me (see link)? Other ideas welcomed. http://www.lawnsprinklershq.com/sprinkler-nozzles/rainbird-nozzles/rai nbird-nozzles-rotary.html |

| You should probably stop posting this all over the place as this is the third thread I have seen it in. However, differently from the other one that I responded to, you said this time that it was a DIY install. Rain bird heads are 10x better then generic orbit. The issue you are having is in your design. Did you calculate GPM, and PSI per zone? It sounds like the Rain bird heads were rated over the available water. If the system is only flowing, say 12GPM, and you have 5 heads flowing 3GPM each, that's 15GPM and the heads are not going to perform properly. You can always try to put a smaller nozzle in. But, as I said in your other post, I think the orbits are functioning properly, they just need to run longer to put down the proper amount of water. <-- another calculation that should have been considered in the original design. |
