Normally I'd say turn the system on & mark the heads that way. You may have already winterized as it is getting cold now. The heads may pop up if you blow the lines out with air again allowing you to mark them & stay dry [img]/forums/images/icons/smile.gif[/img] Connect the dots for an approximation of where the dist. lines are.
I do all the maintenance on the system except for blowing out the lines for the winter as it takes a big compressor. I understand how I can estimate where the lines are - thats a good idea to flag the area. I wish now I had taken photos after the installation showing where the grass was disturbed - it would be a big help now!!

My dad uses his craftsman single stage oil-less 5HP (yeah right) compressor to blow his lines out. I think he does it one zone at a time with good success. Don't know what you've got in the shop for a compressor. $10 in fittings might save you the annual service call.
I've have the Emglo portable commercial twin tanks 3 HP I think. Made for roofing and construction. What I need to do is get a larger tank for storage of the air since it's volume and pressure that I need to blow out the lines.
Even one zone at time its a lot of volume since there are typ 5 heads @ 1.5GPM so need something like 20CFM to do the job.
I might try that thise weekend just for fun and see if it works.
