How to Blow Out a Sprinkler System
Intro: How to Blow Out a Sprinkler System
It usually costs $50 to $100 to have your sprinkler system blown out for the winter. You can do it yourself with a one-time purchase of a $150 air compressor.

Thank you for the video! My boyfriend is a big DIY guy so I'll be sending this over to him. I'll be sure I have a good air compressor and triple check that the sprinkler blowout worked. Am I able to rent an air compressor that's powerful enough to do a blowout or is that something you have to purchase?

How would I go about temporarily defeating the backflow preventer? Air pressure escapes through there preventing me from blowing out the sprinkler lines.

Yes winterizing a sprinkler system above 60 psi for poly or 80 psi for pvc will damage the pipes and reduce the life expectancy. I would assume HOWTOLOU has a very small yard with low volume requirements (drip or micro or small sprinklers). Removing a good percentage of water out of a sprinkler system requires a higher volume compressor, such as a 185cfm compressor. They are worth about $15,000.
HowToLou could also have low cost sprinkler heads, lives on a hill where all the water drains to the low spot and runs out of the low sprinkler, or lives in a dry climate and stops watering two to three months before the ground actually freezes or it doesn't get that cold to freeze solid.
If your pipes are made of LDPE (Poly), the winter breaks will cause small pin holes in the lines where it froze, not a big deal for lateral lines, but any mainline piping with leak continuously. Regardless, the pipes will be damaged, whether you can actually notice it in the future or not is a different story.
