You only want to blow out your sprinkler with the right amount of air volume. If you don’t use enough air volume after flushing some of the water out of the system, the air will rise to the top of the water. And if water flows down, it’ll freeze and put your system in danger of damage.

How much psi do I need to winterize my sprinkler system?
Air pressure must not exceed 50 pounds per square inch (psi) during the blow out procedure. A pressure-regulating valve must be used to avoid over pressurization of the system. Air volume should be high and air pressure low.
Should you leave sprinkler valves open in winter?
Manual valves should be left in the open position throughout winter to prevent repressurization. Some sprinkler heads have both side and bottom pipe inlets. If you use the side inlet, install a drain valve on the bottom inlet to prevent the case from freezing.
