Hi again,
I learned a bit yesterday. I twisted a little knob (bleed screw) on the top of the valve and isolated which valve is associated with the leaking sprinkler heads. It was not the one I thought. Now I guess I will call the installer and ask if I should get a replacement or take it apart. BTW - the links below go to the PDF files for my valve. I was wrong about the model, it must be a PGV and either a 100A or a 100G since it has a bleed screw. Anyway, any input would be appreciated.
