Well there are several things that could go wrong. First go to the nozzles with a small
flat blade screw driver, and you will notice that there is a metal screw, insert the screw driver
and make sure that it is open all the way. How many heads are on that line?? What is your GPM.
It might just be the nozzle.
Sometimes they dont actually make 15'
