Know before you buy
The drain check valve prevents low-head drainage, which stops water from leaking out of the sprinkler head after the irrigation cycle ends. This helps prevent puddling at the base of the sprinkler and reduces the risk of water freezing in the pipes during colder months.
Yes, a 4-inch pop-up height is the industry standard for most residential turf applications. It provides enough clearance to spray over established grass without being obstructed.
The stainless steel riser offers superior durability and resistance to damage from lawn equipment, soil debris, and harsh weather conditions. It is a more robust option that typically provides a longer service life in high-traffic areas.
The Hunter I-20 features a 3/4-inch NPT inlet connection. Ensure your existing underground irrigation lateral lines are compatible with this size before installation.
