Every fall it is a necessity to blow out the irrigation system on the golf course just as you all do at your homes. Except we are dealing with Several miles of pipe and hundreds of outlets for water to get trapped in. If water is left in the lines we have potential for big irrigation repairs in the spring and summer. We use a very large compressor and we turn on every head and quick coupler we have on the course multiple times. We do it in a certain way that forces water to go a certain direction in the pipes which most efficiently moves the water out of the lines.
