I wish I knew about this forum a few weeks ago. I re-lanscaped my yard last year, there is no grass, just dirt. I want to install a sprinkler system before I put the grass down so it can water the lawn as the grass grows. I dug my trenches and layed down 1 1/4 poly pipe. Is this pipe too big? I have 16 GPM at 60 PSI. Thanks, Brett
