To winterize your sprinkler system, it is generally recommended to use 50 to 80 PSI (pounds per square inch) of air pressure. This range is considered safe for most residential systems, effectively removing water without damaging the pipes. It's important to consult your system's manual for specific recommendations, as some systems may require slightly higher or lower pressure. An air compressor with an adjustable regulator is essential for this task, providing control over the air flow to prevent pipe damage.
