Hunter I-20 Sprinklers come complete with factory-installed drain check valve for up to 7 feet elevation change which eliminates landscape damage from flooding and erosion.

The rotor with heavy-duty commercial-grade features that's equally at home in a residential system.

If you have ever desired the convenience of being able to use just one sprinkler rotor to cover all of your needs, here it is. Got a small area for which you don't want to create a separate spray zone? Is a portion of your landscape in sandy soil? Is the landscape a mix of shrub zones and expanses of grass? Does one part of the turf require a higher cut? With all the features on today's I-20 Ultra (most notably its ability to effectively cover a radius range from 17 up to 47 feet) there's a single-sprinkler alternative to stocking a variety of rotors and sprays. With over 20 different nozzle choices, the I-20 Ultra rotor can handle the full range of irrigation needs.

The Industrial-Strength Rotor for Residential and Commercial Irrigation Systems

If you're looking to upgrade over a typical residential grade sprinkler rotor, this is where the search ends. No other irrigation rotor in its class gives you more. Like easy arc adjustment right at the top of the sprinkler, a heavy duty spring with reliable retraction, and a standard water-saving drain check valve that handles up to 10 feet of elevation change. Plus, we now include a rack of nozzles that includes both standard and low angle nozzles (the ideal solution for virtually any landscape situation), as well as the new FloStop(TM) feature that provides the added convenience of easily stopping water flow through a single head without turning off the entire irrigation system. With its ultra-sturdy construction, rest assured you've got a product that's sure to endure - it's even protected by a full five-year warranty! But, for those who still want more, be sure to consider our stainless steel option.
