Irrigation systems do not last forever. While proper design, installation and maintenance strategies can significantly prolong the useful life of a system, eventually all installed irrigation systems require upgrades. Such changes may include adapting to changes in the landscape or water supply, fixing normal wear and tear or to conserve water. Also, at times, an existing irrigation system may require expansion. While you may have to look at the same components and design factors when upgrading or expanding an irrigation system, the processes are not the same, and various aspects of the system need to be carefully reviewed as part of both scenarious. UPGRADING SYSTEMS Upgrading an existing irrigation system may be required for any number of reasons including, but not limited to, the system being worn out, needing better control, changes to the landscape, adding features, improving efficiency, water conservation, government requirements or poor results from an evaluation or audit. One important reason for upgrading an existing system is the sheer number of technological improvements made in the last decade. In the last five years in particular, the technology in irrigation has changed dramatically. This technical revolution includes more versatile controllers and more uniform nozzles to reduce water use and improve efficiencies. Switching to new and improved components will improve the efficiency of the system and save water, as well as energy. Because water used for irrigation is now under intense scrutiny, improving a system makes sense, if for no other reason than public relations or to reduce water and energy bills. The following are a few specific issues to consider when upgrading. 1. Sprinklers/Nozzles Irrigation manufacturers have added significant features to sprinklers, including pressure regulation, nozzle improvements and higher pop up heights. The new sprinklers are also designed and manufactured to last longer and to be more resistant to vandalism. Nozzle improvements over the past few years have greatly improved a sprinkler's ability to apply water uniformly when operated at the proper pressure. Pressure regulation improvements are important because operating sprinklers at a constant and consistent pressure provides a droplet size mix that lays out a uniform pattern of water. Improper or inconsistent pressures provide droplets of similar size and therefore non-uniform coverage. Where before most sprinklers had one round nozzle, the norm today is a nozzle configuration of a number of oddshaped nozzles. New, higher pop up heights keep the turf from interfering with the nozzle trajectory, again providing better uniformity and making less critical the grade at which the sprinkler is installed. 1800-PRS Series Pop-Up Spray Heads Features & Benefits The 1800 PRS Series is designed for areas with high and/or widely fluctuating water pressures, and has all 1800 Series features, plus: Patented PRS pressure regulator built into the stem. No parts to be installed at the site. Saves time and money. Maintains constant outlet pressure at 30 psi (2,1 Bars). Spray heads and nozzles perform best at 30 psi. Ensures maximum spray head and nozzle performance, even with varying inlet pressures. Maintains constant pressure regardless of nozzle used. Restricts water loss by up to 70% if nozzle is removed or damaged. Saves water and money. Reduces possibility of accidents and property damage. Recommended for vandal prone areas. Ends misting and fogging caused by high pressure. Stops water waste. Ensures necessary watering occurs in high pressure or wind conditions. Designed for use with all Rain Bird plastic and brass spray head nozzles. "PRS" stamped on cap for easy identification and maintenance. Five-year professional customer satisfaction policy.
