Sprinkler Blowout And Winterization Service

It doesn’t matter if you drain some of the water; the residual water can freeze, expand and crack flexible or rigid piping. If no action is taken to prevent your backflow assembly from freezing, it could cause extensive damage and costly repairs.

You should winterize your sprinkler system to avoid freeze damage to the system’s essential components. During a sprinkler blowout, high pressure air is blown through the vacuum breaker, valves, and lines to remove all water so it does not freeze during the winter.

Water expands when it freezes, causing pipes and fittings to burst and break. The blowout process involves blowing air out of the lines and draining the vacuum breaker back into the house. This prevents the water in the system from freezing and causing expensive damage to your system or flooding your basement.

Are there any specific times of the year that are the best for blowing out your sprinkler system?
It is recommended that clients blow out their systems in early-mid October to avoid the varying Colorado weather.

A line coupler connects an air compressor to the mainline to perform sprinkler blowouts. As the technician activates each station on the irrigation system and the air, the remaining water will be evacuated.

If you turn up the pressure too much, it can cause damage and injury, but if you turn it down too little, your system won’t be properly winterized. For this job, it’s best to contact an experienced irrigation contractor. If you would like sprinkler technicians to assist you this fall, please contact us.

To prevent freezing, wrap all exposed outside piping and the back flow preventer with old blankets or towels. These are usually located outside the house. Pipes will come out of the house and go underground.

Use a trash bag, trash can, or bucket to cover blankets or towels. This will often prevent damage to your pipes.

Last but not least, turn off the sprinkler system’s main water valve if possible. By doing so, water won’t run if pipes freeze and burst. Water can be drained inside if you know how, but it will still be in the pipes going to the ground. If you drained inside, do not ignore wrapping outside.
