Winterization is a process, not just an air hose.
The purpose of winterization is to remove water that could freeze and damage exposed or shallow components. The right method depends on the system. Some installations have drain valves; others need pressurized-air removal. A provider shutting off secondary water does not automatically drain the private irrigation system.
Winterization methods and equipment
Check the system before shutdown
Identify the private shutoff, controller, irrigation zones and any equipment that needs separate attention. Existing leaks or damaged heads should be recorded rather than hidden by a winter shutdown. Confirm which parts of the system are included and whether any pumps or backflow equipment require a qualified specialist.
Use the right method
USU guidance distinguishes drain-valve systems from systems that need air to remove remaining water. Air pressure and procedure must suit the installed components. Do not copy a generic pressure setting or force air through equipment that is not designed for it. When uncertain, consult the equipment instructions and a qualified irrigation professional.
Plan around weather and your provider
Check current startup and shutoff notices from the property’s actual water provider. Arrange any needed operating inspection while supply is still available, and plan equipment shutdown around the system design and local conditions.
Service requests and availability
Requests are shared with S&S Sprinklers & Landscaping, the current service provider. Confirm address-level availability, the work scope, pricing and any work agreement directly with the contractor.
Useful local guidance
Check current watering advice and your water provider’s notices before changing a schedule or working near the service connection.
