Question
I HAVE TWO RAIN JET SPRINKLER HEADS THAT ARE MY 360'S IN THE MIDDLE OF MY YARD, BUT THEY ARE NOT GETTING THE JOB DONE.  THERE IS DEAD GRASS IN BETWEEN THE TWO.  MY QUESTION IS IF I REPLACE THEM WHAT IS THE EASIEST WAY TO DO IT, OR CAN I JUST RASIE THEM UP TO OVERLAP, AND IF SO HOW DO I RASIE THEM UP.

Answer
Hey Tony, I hope this helps. I doubt just by raising up the heads, you are going to get the heads to throw farther, unless they are hitting the grass and getting dispersed. Either way, between the head and the fitting in the pipe is whats called a nipple. Basically these heads will unscrew from the nipple, and you can screw a new head on. If you want to raise them, then all you need to do is get a longer nipple, and unsrew the old nipple off the pipe and head, and install the longer nipple by screwing it back on the pipe and then the head. Once you dig around the head, you will see what I'm talking about. It's very easy to do on your own. Let me know if I can be of anymore help, thanks and have a good day.
