By overlap that much... each covers their own zone, however of course with any irrigation system if there are two or more zones next to each other they will of course be overlap, since if there isn't then there will be dead spots (assuming the person uses rotor heads. The map is from google so that is all exact. for the heads went outside and turned on all the heads and marked roughly on the map where each is as a general guide for this mockup.
For zone 5 and 6, not exactly sure what you mean. As the zone 5 heads cover the left strip, the 6 cover the right. With the exception of the 5 head on the other side of the fence that connects right into the irrigation system by the house there. There originally wasn't a fence separating the front yard from the backyard when we moved into the house that already had the irrigation setup.
So my plan is to distribute the cups evenly and run with the zone on first for 10 minutes, and then run another 10 minutes with one adjacent zone one, and then another 10 minutes with another adjunct zone on. Then I'd calculate the totals at that time, and mark it as a total run time of 10 minutes rather than 30, like the Orbit instructions say to do. All of that I don't have any issue with.
My issue is still were to put the catch cups. For instance instructions say to put one 2 feet from head. But in there examples the heads are always up against an edge and in a corner http://wateringschedule.com/wp-content/uploads/2013/04/26250-24-rB21.pdf where of course having only one catch cup 2 feet away makes sense. But in real world examples like mine where there are heads in the center of zones and not just in corners I'm confused if I need to have one catch cup on each of the 4 sides of a sprinkler head or if just one, how do I decide which side.
For instance for Zone 7, I put in X's where I assume the catch cups should go for that zone (put 1 2 feet away on all 4 sides). And I would then run zone 7 for 10 minutes, then run zone 6 for 10 minutes, then run zone 6 for 10 minutes, and then run zone 8 for 10 minutes. Calculate the total in the cups, and enter 10 minutes into the calculator for run time.
Does that seem best? Technically according to orbits, sounds like I should also have a catch cup on every diagnal between the 2 feet ones and the corners and sides, but that would add a great number more of catch cups I would have to buy and would rather not unless necessary. Just wish Orbits would have given a few other examples catch cup illustrations rather than the most basic layout.
The default settings for my zones when I enter the precipitation rate for the make/model of those heads, has the suggested run time astronomically high, around 13 hours. Hopefully getting closer to Rachio nirvana.
