I'm trying to repair leaks and adjust. I looked up the method and I have the tool. right arc is fixed, unless you loose the collar and move. the adjustment left is adjusted like PGP. However the "Cap" on top of the sprinkler has no access holes for the tool. I see where it suppose to be 2 round detents. I've cleaned the top of soil. Keep in mind this system was installed by previous owner. It has a Rain Dial Plus keypad. Some of the heads do have the nozzle adjustment and I was able to adjust. Also the soil level over time has raised up higher I think the height of the head is a little low. Red nozzle jets, except for one which is a Toro brand which has 2 different jets depending on program. Again I didn't install the system. It worked ok until my buddys at Fios Installation Inc. came along for street hookup.

One thing I didn't do is check prices on new heads, Maybe that would be best. They seem pretty reasonable. Well comments are still welcome, if I can use some of them that's fine.

Well Bavara, looks like you answered your problem, wife says it's ok to buy new ones?

Actually she said yes, and with that Andy we can delete this post.
