I am in the process of planning and installing a Rainbird DIY kit.
I don't expect this to be anywhere close to a pro installed system, but will make it much easier to water the lawn on a scheduled basis. We are looking at a rather dry summer here, and our clay soils shrink when dry and cause foundation damage. I figure a irrigation system should keep the soil moist and keep the grass from turning into dust.
When it comes to sprinkler placement, I see that the general trend is to place sprinkler heads along the perimeter and have each do a 90 degree sweep. In this pic I found that resembles my backyard, you can see how they use 6 heads to get complete coverage of the rectangle area.
But if the sprinkler heads can do 360 degrees of rotation, then I don't see why I wouldn't put the heads directly in the middle of the lawn and try to get circles of coverage that overlap by a foot. This way I can use 4 heads to cover 90% of the rectangle area, and the remaining 2 heads can be put on the sides where there is grass that needs watering. (not my pic but conveniently similar to what I am suggesting)
Is there some functional reason to not put sprinkler heads in the middle of a lawn or is it just aesthetics/coverage?
