Benefits of winterization

Protect pipes from freezing

Water left in pipes expands as it freezes, causing cracks or bursts. When pipes split, you may face excavation and thousands of dollars in repairs.

Avoid costly repairs

Winter damage to irrigation systems can add up. By draining your lines now, you avoid springtime repair calls and unexpected bills.

Extend system lifespan

Removing moisture and powering down your controller prevents corrosion and valve failures. Proper winter care can add years to your sprinkler system (Oasis Landscapes & Irrigation).

Plan before first freeze

In Sherwood Park, nighttime temperatures often dip below 32 °F by mid-October. Aim to finish winterization by early October to beat sudden cold snaps.

Consider local factors

If your property borders Strathcona Science Provincial Park or lies near the Serpentine River, frost can hit earlier. Watch local forecasts and schedule your service with a buffer of at least one week.

Compare drainage methods

According to The Home Depot, there are three main winterization methods: manual drain, automatic drain, and blow-out method (Home Depot).

Manual drain method

Open manual drain valves one zone at a time until water stops flowing. This method is low-cost but can miss pockets of water in low spots.

Automatic drain method

Automatic valves release water once pressure drops. It’s fast, but you may still need to drain lines between the shut-off valve and backflow preventer.

Blow-out method

Forced compressed air clears all water from pipes and sprinkler heads. It’s the most effective choice for PVC and polyethylene systems.

Equipment needed

• Air compressor rated for your system’s flow (GPM/7.5 = CFM)
• Airline hoses and fittings
• Protective eyewear and gloves

Pressure guidelines and safety

Do not exceed 50 psi on polyethylene pipe or 80 psi on PVC to avoid damage (Hunter Industries). Always wear eye protection and avoid blowing air through backflow devices. Strathcona County’s Cross Connection Control Program reminds owners to maintain and test approved backflow devices.

Good news, once you have the right pressure and gear, blow-outs take just minutes per zone.

Guide to blow-out method

1. Shut off main water supply
   Locate the shut-off valve near your house and turn it fully off.
2. Release system pressure
   Open a manual drain valve or sprinkler head to let out residual water.
3. Connect air compressor
   Attach airline to the blow-out port or a spare zone port.
4. Set compressor pressure
   Adjust to 50 psi for polyethylene or up to 80 psi for PVC (Hunter Industries).
5. Cycle through each zone
   Activate stations from farthest to nearest until no water sprays from the heads.
6. Remove air lines and close valves
   Turn off compressor, detach hoses, then close all drain and blow-out ports.
7. Power down controller
   Set your irrigation timer to OFF or RAIN mode to prevent accidental activation.
