From the Manufacturer
Toro’s 570 fixed-spray sprinklers are tougher by design. Ideal for small 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. The Toro 570 fixed-spray Sprinkler includes a 570 4-inch pop-up fixed-spray sprinkler and a pre-installed 15-foot variable arc nozzle (VAN) for adjustable patterns from 0-360 degrees.
