I have 11 zones and they're typical 4-5 heads each. Last two years I watch the lawn companies guys come in with huge air compressor and blowout my lines, zone by zone. I figure I could save some money and also have an air compressor for use on the side as well. They pretty much shut my water valve and hookup the air line and then open up each zone by zone and that's pretty much it, so I figure I tried it with a compressor and killing two birds with one stone.
30 gallon 7.7cfm @ 40psi. It's the husky 175psi 30 gallon oil black tank from homedepot.
When I ran zone 1 it took 3 times, it watered up and then turn fine mist and then no mist. Great, same for 2 and 3 and so on, but some zones no water comes out, but the head pop up blowing air, I can see the head pop up even though there's nothing coming out. It's zone 10 that scares me, it doesn't pop up at all and no mist, no water, but I can hear the air at each head and I check the head in the ground is spinning, but just doesn't pop.
My quesitons is does/can certain zone/s drain down into other zones once the other zones are empty? and/or does the higher(elevation) zones sink/flow(gravity) down into the lower zones because theres little or no water in those zones? When the commercial guys do it, I see water from every zone come out and they do it in the same order that I do. My gut says zone 10 should/might still have water, but I can't confirm and also, my zone 1 blew out a lot of water compare to the rest as well?
Obviously i have to let the compressor recharge to full tank between blowouts, but I keep the pressure at 70 and as soon as i plug in the air, it quickly drops down to 40 and I increase the pressure back to around 60. Pretty sure I didn't blow any up with higher than 60-65 psi.
What are you guys experience?
