What pressure blow out sprinklers?
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.
Can I blow out sprinklers through backflow preventer?
Do not blow the system out through a backflow or pump. First blow out the system, then drain the backflow or pump. Do not leave the manual drain valves open after the blow out.

Turbulence and water velocity increase dissolved air.
Why is my sprinkler system so loud?
