I just had a sprinkler system put in to make sure our new shrubs survive, but am concerned the drip irrigation in our flower beds isn't delivering enough water. I first noticed small wet circles about 6" in diameter around each emitter, and asked the installer about it when he came back the next day. He said this is likely because it was only set to run for 40 minutes, whereas he would recommend 1hr 15min. So tonight I ran them for an hour and 15 minutes, but the wet circles are just barely larger than before! Do I need to have him come check this out, or is this normal? All I wanted to was to make sure the beds got better and more consistent watering than I could provide by hand, but it's looking like nothing is getting watered unless it happens to be right next to an emitter!
