This pressure compensating sprinkler is taking the industry by storm!
SuperNet Pressure Compensating (PC) Sprinklers can water more trees on the same zone with equal water distribution regardless of row length or elevation changes. When the tree is young, replace the stock spinner (purple or black) with the blue spinner with the deflector (sold separately) to water the root ball. As the tree grows, break off the deflector to expand the watering area. For mature trees, remove the blue spinner and replace with the stock spinner.
