Sprinkler Blow out question:

[BPTactical]

The pancake should do it, you just don't have much air volume to work with so it will take a while. Use the manual bleeder valves for each zone valve instead of relying on the manual setting on the clock.
Leave all ball valves @ 45 degrees, don't forget to purge the backflow preventer as well.

Where would those be and what would they look like? Last year the sprinkler guy just hooked up his compressor and manually cycled through the zones in the control panel.
