Brand new system - the installer/tech demonstrated how to adjust the coverage area and water flow volume. I'll be damned if I can do it.
I have several zones that overlap and would like to reduce the output of the opposing heads in the zones so they don't give me double coverage.
any who - here's the head and various markings.
He gave me a white plastic tool to insert and twist, but yesterday all I accomplished was getting myself soaked. I think he also used a very small screwdriver to reduce/increase flow.
Any help would be appreciated. Thanks in advance. Bill K
