As the newest member of Hunter's popular MP800, the MP815 extends a 0.8 in./hr (20 mm/hr) matched precipitation rate to a convenient larger maximum radius of 16 ft. (4.9 m). Thanks to this capability, the MP800 offers increased system-level design and retrofit applications. The previously released MP800SR covers distances as short as 6 ft. (1.8 m). Now, with the addition of the MP815, the MP800 can irrigate spaces up to 16 ft. (4.9 m) with uniform coverage and the same 0.8 in./hr (20 mm/hr) matched precipitation rate. Hunter is the only company to offer three matched precipitation rate options for pop-ups, giving customers more choices for irrigation management. To maximize water-use efficiency, choose the standard MP Rotator, which has a slow precipitation rate of 0.4 in./hr (10 mm/hr). This is perfect for tight soils, as well as steep slopes to eliminate runoff. Use the 0.8 in./hr (20 mm/hr) precipitation rate of the MP800 for medium-grade soils, gentle slopes and small spaces.
