When blowing out lines.........

.....do I just open the bleed valve on the valves or do I need to set the controller to open the valves?

Just manually run through the valves from the controller.

For the average residential system we use anywhere from a 160-185CFM compressor. It's a good sized compressor, but we're in the business of getting them done quick! We typically run them about 60-70 psi. At these settings we can actually blow out roughly 15 Rotors at a time. Remember, it's the CFM rating that clears the water from the line.



Blow out time varies depending on size, layout, and type of zone being cleared. Run the compressor until the last head/s have been misting for 30 seconds.

Yes, I've read about CFM but what if I have all day to do it? Will regular 30 ish gallon compressor do the job?

Depends on the size of the zones. I know alot of homeowners that refuse to pay the money and opt to do it themselves. Though, I don't condone using a shop compressor, many people use them. It will more than likely take you all day to do it.

In my case my longest run is 80 feet of 3/4 poly. I have a small tankless comprssor and my neighbor has a pancake tank compressor. If they can't do it I'll call in the local pro.

At my local Home Depot, you can also rent an air compressor (gas) for $40 a day. It is about a 10 gallon one. Don't know if that would do the job. Probably, beacause as a homeowner, you don't have to do many systems a day. Just yours. For me, I don't mind taking a day to do it, as long as its done right, and its a good price.
I'm no expert..........YET! :D I just like to suggest things and learn... :thumbsup: See what the pro's have to say first.
