Winterization for Irrigation Systems

The Importance of Winterization for Irrigation Residential Irrigation backflow refers to the unwanted reverse flow of water in a plumbing system, which can contaminate the potable water supply. Irrigation systems often draw water from various sources, including municipal supplies or wells, and they can be susceptible to backflow due to changes in pressure within the system.
As a professional expert, we always recommend a blow out to the system and technicians know the amount of pressure that may be used in order for the blow to be proper and no damages occur in the piping system. The backflow is a good place to start with blow out and safety should always be considered when using compressors or any type of device distributing air.
In the State of North and South Carolina, RPZ type backflows and Double check backflows are mainly used in these geographical areas. And Code enforcement is important to keep these devices safe and public water from being contaminated.

Backflow can occur for various reasons, including:
Backpressure:
When the pressure downstream of the backflow prevention device is greater than the pressure upstream, it can cause water to flow backward.
Back siphonage:
This occurs when there is a drop in pressure in the supply line, causing water to be siphoned back into the potable water system.
To prevent backflow, irrigation systems are equipped with backflow prevention devices, such as:
Reduced Pressure Zone (RPZ) Assemblies:
These devices maintain a reduced pressure in the system to prevent backflow.
Double Check Valve Assemblies**:
These consist of two internal check valves that provide a barrier to backflow.
Pressure Vacuum Breakers (PVB)**:
These devices prevent back siphonage and are installed above the highest point of the irrigation system.
Winterizing Irrigation Systems
Winterizing irrigation systems is crucial, especially in regions that experience freezing temperatures. Here’s why winterization is necessary:
Preventing Pipe Bursting:
Water that remains in the irrigation pipes can freeze when temperatures drop. As water freezes, it expands, leading to cracks or bursts in pipes, valves, and fittings.
Protecting Backflow Preventers:
Backflow prevention devices can be particularly vulnerable to freezing. If left with water inside, they may sustain damage, leading to costly repairs or replacements in the spring.
Ensuring Functionality**:
Properly winterized systems will function correctly when reactivated in the spring. If issues arise due to lack of winterization, it can disrupt watering schedules and affect plant health.
Winterization Process
The winterization process typically involves:
Shutting off the water supply** to the irrigation system.
Draining the system**: This includes manually draining the mainlines and zones through the valves.
Blowing out the lines**: Using an air compressor, the remaining water is blown out of the system to ensure no water remains in the pipes.
*Protecting exposed components**: Insulating backflow devices and other exposed components can help prevent frost damage.
Storing hoses and equipment: Any hoses, fittings, and other removable items should be securely stored indoors.
By adequately winterizing an irrigation system, property owners can prevent damage, ensure reliability, and maintain water quality for future use and Commercial Systems that may be damaged by freezes that may be a costly repair or replacements can be costly to the homeowner. A few preventions can save money down the road and years to come with general simple steps.
