Toro?s 570Z pro series fixed-spray sprinklers are tougher by design. Ideal for small (5 Feet to 15 Feet) lawn and shrub areas, all seals are designed to prevent leakage around the riser when the system is turned on. It also keeps dirt and debris from entering the sprinkler. The seal prevents flushing on pop-up so that there is no water loss at start up. This means you can install more sprinklers per zone. Turn designs into beautiful landscapes without sacrificing creativity.
