Learn how to blow out your sprinkler system, protecting the lines from cracks and leaks.
These adapters are regularly used for winterizing RVs, so they should be relatively easy to find.
The only exception to this is if the yard includes uneven terrain, like small sloping hills.

In this case, start with the sprinkler zone that is on the highest level first.
Slowly launch the compressor valve, gradually adding additional air pressure as needed.
When the pressure is sufficient, you should start to see water coming through the sprinkler head.
The Spruce / Sarah Lee
The air pressure should not exceed 80 PSI for PVC piping or 50 PSI for polyethylene piping.
Move through each zone until all sprinkler zones have been blown out.
It’s a good idea to keep the PSI below 50 to avoid damaging the irrigation lines.

Blowing out a sprinkler system doesn’t take a lot of time.
This means you should have the sprinkler system winterized before the temperatures drop below 32 degrees Fahrenheit.
