Hi, My lawn has a dry spot and I think it is because the pressure to the water is too high, I see a lot water actually sprayed outside the lawn. So yesterday I did a "fix", after pull up the head, I see there is a little screw on the top, I tried unscrew it, not totally, just want to make it loose. Really I did not know I make it or not because it is so tight, all I see is the whole head is turned with my screwdriver together.
The problem is when I tested it, it did not work as I expected: it is a 90 degree head, but the water come out 360 degree now!
Do you know what might be the problem?
Thanks.
