Irrigation guys, I was doing a mulch install for a guy last week and I hit a head with the bed edger. Of course this tore it all to pieces. The homeowner had them all flagged but this one got missed. It is positioned in the corner of the front lawn and I am thinking that it is supposed to throw a 45 degree pattern but I am not sure. How do I tell what head I should purchase to replace it with. I do not do irrigation and I am only slightly familiar with it however I have noticed on four different jobs this season that the original installer placed the heads right in the transition zone from grass to the beds. Is this normal positioning as it creates problems when trying to edge a bed? We live in a small area and only have one guy that really advertises irrigation. I think he may have done all of these original installs and maybe that is just his method. I have tried calling him to get the head replaced but he will not return a call. Any help would be appreciated.
