The pressurized irrigation system will be shut off on or around October 15. Please plan your watering schedules accordingly. When the system is shut down, please be sure to turn off your sprinkler system, open any manual drains, and also be sure to close the main valve in your PI box. This will prevent unintended flooding in the Spring, and may help avoid frozen and broken pipes this winter.
Every season, it seems that a handful of residents forget these very important steps and suffer unnecessary flooding in the Spring. Please don’t be the one affected next year; take a moment now to completely turn off your sprinkler system.
In order to close your main valve, open the PI Box that is located somewhere in the yard; typically near the sidewalk or street. When you open the lid, be sure to keep an eye out for spiders that like to hide in these kinds of spaces. To close the valve, turn the handle so that it is perpendicular to the pipe, as shown in the picture. Then replace the lid, making sure that it is securely in place.
