Quick answer: Yes. Winterization performed incorrectly can damage irrigation components. Compressed air must be used with appropriate pressure, airflow and procedure for the system rather than simply connecting a compressor and forcing as much air as possible through the piping.
Why compressed air requires care
Irrigation components are designed to operate with water, not uncontrolled compressed air. Excessive pressure or an improper procedure can stress valves, fittings, sprinkler heads and other components.
Pressure and airflow are not the same thing
A successful blowout depends on moving residual water through the system while keeping operating conditions appropriate for the irrigation components. More pressure is not automatically better.
Zones should be handled deliberately
Winterization normally works through the irrigation system systematically rather than leaving uncontrolled air trapped against closed components.
Why system design matters
Zone size, piping layout, water source, valves and exposed components can differ between properties, so one procedure is not appropriate for every system.
