    My system has a main in that has a valve to shut off the water but the system still is full of water (freeze/crack potential). Just past the shutoff is a male air fitting, so it looks like I should be able to hook up a compressed air line and 'blow the air out'. However, after hooking up air............nothing happens.

    Any ideas? /forums/images/graemlins/confused.gif

    I would agree. If the system is electronically controlled, which most are, just cycle it through all your zones with the compressed air hooked up and the water turned off. The heads should then pop up by zone and you're golden when all the water has finished coming out.

    This is most likely your problem. Gotta actuate those electric valves. /forums/images/graemlins/smile.gif

    Hope it helps,

    All my sprinkler valves have manual override levers. Flip the lever and it activates that zone.

    Also, for a spring project, you should take a look at the automatic drains at Home Depot. /forums/images/graemlins/shocked.gif Put one in the lowest section of each zone and the water will drain out by itself. They're like $2 each. /forums/images/graemlins/thumb.gif
