In our neighborhood several homeowners get together and rent a large compressor. (One of the neighbors needs to have towing capability on truck or SUV). Ask the rental agency for an extra 50 feet of hose and a connector. You have to look to see what kind or kinds you need. Some blow out pipes are copper, others PVC.

Turn off the water supply to the irrigation system. You should have shut off valves on both sides of your backflow preventer valve.

There is a blow out pipe located on the outside of the house, usually where water service enters. Remove the cap and connect the compressor hose to the pipe, being careful not to damage the threads. Open Zone 1 on your system and turn on the compressor. When all the water and most of the mist has blown out, sequentially open the other zones. Replace cap on the blow out pipe, then move on to your neighbor's system.

We can rent a compressor for three hours for less than $60and do four or five systems. The sprinkler people charge 90 bucks apiece. As Red Green says, "if your wife don't find you handsome, at least you can be handy."
