Historically, most irrigation systems don't have pressure regulated sprinklers which often leads to sprinklers operating over pressurized. Over-pressurization can lead to water losses and contribute to uneven watering.
Pressure-regulating spray heads are a developing technology designed to regulate pressure to optimal performance. Pressure-regulating spray heads include built-in regulators that maintain a more constant pressure for optimal nozzle performance.
WHY IS PRESSURE REGULATION IMPORTANT?
Two reasons: They will save water and it is likely soon to be the law.
WATER SAVINGS: Compared with non-regulated, pressure regulated sprinklers will use about 20-25 percent less water. And if the nozzle breaks, pressure regulators are estimated to save 70 percent of the water that might have been spilled if using an older, non-pressure regulated system.
PRESSURE REGULATED SPRINKLERS NOW REQUIRED BY LAW: California and Washington along with Colorado, Hawaii, Vermont have all previously adopted banning the sale of non-pressure regulated spray heads in previous years. This past year, the Oregon Landscape Contractors Association sponsored a bill to do the same in Oregon. We firmly supported this effort which was signed into law this year. Although we hate new regulations, but this one makes good financial sense.
