| Hi, first post here but I've been searching and reading through old posts for a while now. I'm going to be installing a new sprinkler sytem for my yard in the next few weeks and I was hoping to get some advice on the proposed layout. Right now I'm just concerned with the front and side lawns. I will add irrigation for the flower beds and back lawn at a later date. I've read through everything on the irrigationtutorials.com site but I'm still a little lost on how to properly space the heads.
I have attached two pictures (hopefully) of the layout. The first layout is what I would like to go with, using Hunter PGP rotors for the front lawn and PGJ rotos for the side lawn. The green box outlines the property, the red dots are the heads and the grey dashed cirles are the spray radius. The second picture is an alternate layout I had for the front lawn, but I don't think this provides enough coverage, but I'm not sure? Any advice or comments would be really appreciated. Thanks,
|

| r andersen, the two offerings I have are:- 1. Designs usually factor in a 50% overlap. In practice this means spacing the heads one and a half times the distance of the radius of the 'throw' or coverage. 2. Where more than two heads cover the same area, localised over-watering may occur. When this happens, you can compensate by stepping down the size of one or more nozzle(s). Most reputable manufacturers provide a selection of nozzles rated in gpm. |

| Really? Everything I read said that you needed 'head to head' coverage and I thought I was actually light in coverage in some areas? Any other advice would be appreciated. Thanks, |

| consider Accurain.com sprinklers. You would need only 4 - 5, and they never overwater, being flexible enough to allocate water to programmable zones. |
