I am completely new to the world of sprinklers and home ownership, so please bear with me.
As near as I can tell, my system has about 20 GPM.
I have some sort of Lawn Genie sprinklers that pop up from a large green housing and contain an impact head inside. I have only 5 of them.
Sorry, I only have MSPaint.
The one in the upper-right hand corner is broken, so it is jammed in one position (if I set it normally, it just spins around and never reverses). Since I have to replace it (or part of it), I was wondering if I should look at replacing all of them to better units or redesign the system.
