Sprinkler Winterization and Blowouts
Sprinkler Blowout Services in Spokane
Protect Your System Before Winter Strikes
Sprinkler blowouts begin October 1st, but we start scheduling as early as September 1st and spots fill up quickly.
When fall temperatures drop in Spokane, water left inside your sprinkler system can freeze, expand, and cause serious damage. That means cracked underground pipes, burst backflows, broken sprinkler heads, and costly spring repairs.
At Greenscape Landscaping, we provide professional sprinkler blowout and winterization services to protect your system through the cold months. Using compressed air, we safely clear water from your lines, heads, and valves, ensuring your system is shut down properly for winter.
Blowout pricing is $74.95 for the first 5 zones and $4 per zone after that.
What Is a Sprinkler Blowout?
A sprinkler blowout is a key part of winterizing your irrigation system. We use commercial-grade air compressors to flush out all remaining water from pipes, sprinkler heads, and valves. It’s fast, effective, and essential for preventing:
- Flooding and leaks in spring
- Cracked underground pipes
- Damaged backflow preventers
- Busted sprinkler heads and fittings
Sprinklers may need extensive repair if not blown out correctly
We take pride in ensuring your irrigation system is properly put to bed for winter
Our Sprinkler Blowout Process
We take the guesswork and the risk out of winterization:
System Shut-Off
Your technician first confirms the water supply is fully off and that the shut-off valve is functioning correctly.
Component Check
We locate all key components of your irrigation system, including backflow preventers and valves, to ensure nothing is missed during the blowout.
Air Purge
Using a towable 185 CFM professional-grade air compressor, we safely push air through each zone to remove all remaining water from the lines and heads.
Drain Open & Completion
Drains are left open for added protection, and your technician leaves a detailed invoice at your door to confirm the service is complete.
Our trained team works efficiently, treats your property with care, and guarantees the work. If we perform your blowout and you still experience freeze damage, we’ll repair it at no cost.*
Why Blowing Out Your Sprinklers Matter
In Spokane’s freezing winters, winterization isn’t optional, it’s essential. Even a small amount of water left in your system can freeze, expand, and crack pipes, fittings, or valves. These issues often aren’t discovered until spring when it’s too late.
DIY blowouts may seem like a quick fix, but they often use the wrong pressure, miss key components, or leave residual water in the lines.
Hiring a professional ensures:
- Your system is fully cleared and properly shut down
- You avoid expensive repairs come spring
- Your sprinkler system lasts longer and runs better season after season
- Peace of mind knowing the job was done right
