It's that time. It's time to put the many many sprinkler heads that keep the lawn green into a winter's hibernation. The frost warnings are starting to come in--and we don't want to freeze the lines.
So we kill the electricity to the pump, pull the intake, and fire all the lines with 140 lbs. of compressed air. When you can no longer see water coming from the heads--and hear nothing but a hissing sound--then you've completed your mission till next year.
The big bopper compressor in the basement is happily employed filling inner tubes, water toys, and air mattresses--but it really shines come irrigation day.
