<br />Your Distribution Uniformity is <br /> <br />% Fixed <br /> <br />% Rotor. <br /> <br />Water Pressure <br />Most sprinl(ler heads apply water more efficiently at a water pressure between 30 (fixed pop-up <br />heads) and 50 (rotor heads) pounds per square inch (psi). Sprinklers can't cover the desired area if <br />the pressure is either too low or too high. If your pressure is low, try watering when less people <br />are watering or modify your system so there are fewer sprinl(lers on each valve. High pressure <br />causes misting and wears out your sprinl(lers faster. If your pressure is high, pressure regulating <br />heads or a pressure regulator can be installed to lower pressure, minimize misting, and maximize <br />irrigation efficiency. <br />Your Sprinkler head pressure is fixed psi., rotor: psi. <br /> <br />Evapotranspi ration <br /> <br />Evapotranspiration (ET) is one of the most important things to consider when scheduling run <br />times for your irrigation system. ET is a conversion of water from liquid to vapor and is the <br />amount of water needed for the plant to survive. This is a simple concept that may help conserve <br />water. <br /> <br />Irrigation Scheduling <br /> <br />The following schedule has been completed based upon your soil type, distribution uniformity <br />precipitation rate and estimated evapotranspiration. It is meant to serve as a guide --- keep an eye <br />on your lawn and mal(e adjustments as needed. <br /> <br />Short cycle watering is important in heavy soils, slopes, or when sprinklers have a high <br />precipitation rate. Run through all zones at one-half or one-third the total time needed then re-run <br />the zones again by adding additional start times. This will help prevent puddling and runoff. <br /> <br />Recommended Waterina Schedule <br />This schedule can be used during non-restrictive years. <br /> <br />SPRAY ZONE: <br /> <br />Month Times/week Cycles Minutes Total Minutes Total <br /> per waterina Minutes per <br /> week <br />May 1.5 <br />June 2 <br />July 2 <br />August 2 <br />September 1 <br /> <br />30 <br />
