What kind of sprinkler heads are you using? Rainbird rotors have adjustable nozzles that are quite inexpensive. perhaps you should just change the nozzle to a lower output.

What I would do is first verify that the layout is properly designed. Rainbird will send you a layout design for free. It will take a bit of work on your part to confirm your water output and other specs but then you'll be sure that your design it proper....

but essentially, you can do whatever you want. You can pull out a head and cap it, move them around, etc. But it just might be a good idea to get a design from a professional.

local installers might charge or even give a free design but I've had bad luck with installers in my area.

So my drawings of the arcs are probably not true to scale. The zone that is in question has 5 heads in the line. The radius of the nozzle is about 25'. They are all Rainbird 5000 series. Distance from sprinkler #1 to #2 is about 21'. Distance from #2 to #3 however is just over 30', as well as being nearly 30' away from the sprinkler heads along the back edge of the property. The area that #2 and #3 cover is also sloped so some of the water is lost to runoff. #3 is about 25' from #4 but is in a flat area and has decent coverage from the two other nearby zones. The last sprinkler head in that zone is also right at 25' away from #4, but is in a flat area and is only about 10' from an R-Van Rainbird rotary sprinkler head as well as only about 15' away from another rainbird 5000 (which only has a half arc so it puts down twice as much water over the same amount of time.) That area is also between my house and my neighbor and ends up getting shade most of the day. Because of the R-Van rotary and the 5000 series being so close to that last sprinkler, that area ends up being over watered.

My biggest question is whether it would work to cap off that #5 sprinkler head and add a new sprinkler head in between the current #2 and #3? I am just trying to figure out the best/easiest solution.

Jeremy, I'm off to an appointment, but when I get back, I'll take another look at your comments. I'll get back to you later, O.K......Ann

Jeremy, the best thing I would tell you is to call an irrigation contractor to look at your system in person. There are many different nozzles for the RB 5000 series. Nozzle changes could solve some of your coverage issues, but changing nozzles means that lateral line sizes would need to be known. I think having a contractor look at your situation would actually be the "best/easiest" before adding another head and eliminating #5 head. Depending where you live, find a Rain Bird distributor and asked them for recommendations of KNOWLEDGEABLE irrigation contractors. If you have questions, let me know.

Thanks for the feedback. I will get in touch with someone soon.
