Rain Bird 8SAPROPR Pressure Regulating (PRS) High-Efficiency Pro Rotary Sprinkler, Hand Adjustable 45° - 270° Pattern, 8' - 14' Spray Distance, 4" Pop-up Height. High pressure in irrigation systems causes wasteful water loss through misting and over-spraying. Rain Bird’s patented PRS Pressure-Regulating Sprays eliminate this costly problem. Our built-in regulator maintains an ideal water pressure of 30 psi to maximize watering efficiency with up to 75% water savings over traditional pop-up nozzles. Precise water-pressure ensures optimal nozzle performance and water distribution; even in windy conditions. Approved for sale/meets all pressure regulator legislation requirements in CA, CO, HI, VT, MA, ME, NY, OR, RI, WA, and Washington DC. The remarkable Rain Bird 8SAPROPR sprinkler combines the world #1 installed commercial-grade 1800 Series body with a PRS regulator and water-saving professional R-Van rotary nozzle! Multiple rotating streams of large water droplets deliver wind-resistant, uniform coverage throughout the pattern. Equipped with an adjustable 45° to 270° nozzle the 8SAPROPR can replace existing quarter, half and adjustable pattern conventional pop-up sprays or be used in the same zones. It’s a perfect solution for irrigation systems with low water pressure or compacted soils. The highly efficient water delivery reduces soil erosion, wasteful water runoff and is gentle enough for newly seeded areas. Water and nutrients penetrate the soil, saving water and money while helping maintain a healthy landscape. Nozzle design allows easy hand adjustment of distance and pattern at the nozzle and potential clogs are cleared by pulling up on the nozzle to flush out debris all while the water is running and without tools!! The extended 8’ to 14’ spray distance covers more area with fewer heads and is ideal for slopes and hillsides. The commercial-grade 1800 Series body is famous for reliable operation and built-in long-life from heavy-duty materials, superior components and features. Exclusive co-molded wiper seal and encased plastic "cage" deliver unmatched resistance to grit, pressure and the environment. A heavy-duty plastic body and cover resist edger strikes, pressure spikes and unexpected abuse. The tapered pop-up neck and a precision flushing action at pop-down clear debris for positive stem retraction in all soil types. A stainless-steel, heavy gauge spring ensures flush retraction of the stem after every watering. A two-piece stem ratchet mechanism provides easy pattern alignment and added durability. The protected closed-case design is ideal for "creeping" grasses, sandy soil, and other harsh surroundings. A pressure-activated seal eliminates excess “flow-by” allowing more heads to be installed in the same zone; reducing run times and saving money. Specifications: 0.6” per hour precipitation rate, operates at 30 psi with no misting. R-VAN Nozzles meet the requirements of the ASABE/ICC 802-2014 standard. May be used with Rain Bird 5000 Series MPR Rotors on the same zone. **Also available in a 360° model (8SAFPROPR). Rain Bird "The Intelligent Use of Water"
