I finally decided to turn the sprinklers on at the new house yesterday to see which zones were where (not labeled), I noticed there was one area in the back yard that wasn't getting any water (probably a 4x5' area), and when I would adjust the spray of the heads closest to it, it still wouldn't get there. So, I'm thinking about adding an additional head to that area to keep it watered. I've fixed busted lines and replaced heads at my old house, so I'm guessing that all I really need to do is to T into the existing lines and run an additional PVC pipe out to the area I want. Is it really that easy, or is there something else that I'm not thinking about?
