Getting water out of the system before the first hard freeze, and back in once the risk has passed.
Winterization is not a precaution against something unlikely — it is standard maintenance against something that happens every year the system is not blown out. Water trapped in a lateral line or sitting in a backflow assembly has nowhere to expand into when it freezes except the pipe wall itself, and a split line or a cracked backflow device is a spring discovery, not a winter one, because nothing shows until the system gets charged with water again.
Spring startup is the other half and it is not just turning the water back on. It means bringing the system up zone by zone, checking for the leaks winter left behind, resetting the controller for the season ahead, and confirming backflow prevention is intact before it is relied on for the summer. Skipping straight to full pressure on a system nobody has checked since October is how a small winter crack becomes a flooded flower bed in May.
