I have Toro 570 series pop ups ( 4'x30' side strip) spray sprinklers along either side of my driveway. There is Liriope planted along either side of the driveway also... very pretty, but the pop-ups aren't tall enough to pop over the Liriope and water the plantings behind it also! Can I replace the pop-up with 12"? What product would you suggest? Can I just unscrew the old pop-ups and screw in the new ones, or is it more complicated than that?! I think there will still be enough water placed on ...
