The MP Rotator Standard Nozzle Family has a matched precipitation rate of approximately 0.4 in/hr (10 mm/hr). This means any MP Rotator Standard model at any arc or radius can be placed in the same zone. The MP800 Family has a precipitation rate of approximately 0.8 in/hr (20 mm/hr). Since this precipitation rate differs from the standard line of MP Rotator Nozzles, you should zone MP800 Nozzles separately to maintain matched precipitation within each zone.
A precipitation rate is the depth of water applied to the landscape over a period of time. Different types of sprinkler nozzles apply water at different precipitation rates. Matching your precipitation rate, or application rate, to your soil intake rate will eliminate the hazards of runoff and help conserve water.
MP Rotator Standard Nozzles have a slow precipitation rate of 0.4 in/hr (10 mm/hr) for tight soils and steep slopes. Use the 0.8 in/hr (20 mm/hr) rate of the MP800 Family for medium-grade soils and gentle slopes. Spray nozzles with precipitation rates of 1.6 in/hr (40 mm/hr) are great for sandy soils.
Matching your precipitation rate to your soil intake rate will eliminate the hazards of runoff and help conserve water. With two different precipitation rate options with the MP Rotator Nozzle, you can now choose the best high-efficiency rotary nozzle for your plant material, soil type, and slope.
- MP Rotator Standard Nozzles deliver water slowly at a rate that most soils and slopes can effectively absorb.
- MP800 Nozzles deliver delivers water at half the rate of a spray nozzle, better matching typical soil intake rates.
- Standard sprays apply water at a rate much higher than most soils can absorb, causing runoff in most soil types.
