Book before the first hard freeze — typically early to mid-autumn depending on your region. Providers book out fast in the final two weeks before frost, and a cracked backflow preventer or split manifold costs far more than the blowout.
Answers from the providers who do this work every day.
Anywhere ground freezes, yes. Water left in lateral lines expands and splits PVC and poly fittings underground, and you will not find the damage until spring startup floods a zone.
Usually not safely. Shop compressors deliver too little volume at too much pressure, which pushes water past heads without clearing lines and can blow out seals. The job needs high CFM at low PSI.
Most residential systems take under an hour. The crew works zone by zone, clearing each line until only mist comes through, then shuts the main and drains the backflow assembly.
