My attempt at blow outs
I've got a 6.1 SCFM compressor the other day to give it a try on my sprinkler system. Well I guess it didn't work well. I went 2 times over each zone. First time it worked fine: heads came up blowing air-water mix. On the second time sprinklers on the longest runs didn't come up. I could hear air blowing through. Smaller zones came up fine. I have small flower bed zone with 8 six inch pop-ups and VAN nozzles that don't come up either. My guess I eliminated about 90% of water but that is obviously not enough.
In any case I scheduled a "pro" with bigger compressor to do it.
