    What is a good range of CFM to blow out a 1" 13 GPM sprinckler line?

    We get the 185 as well and can do 2-3 zones at a time. These are all residentials. Commercial is usually one at a time.

    By doing 2-3 zones at a time and with out meeting the customer (having them shut water off before we're there) I can do 15-25 in a day. Have done 30 in one long day before. Schedule as close as possible to avoind down time driving.

    I play with the adjustment valve and get it to where the compressor shuts of at 70+ psi and runs wide open with one compressor valve open at 50-60 psi. We don't shut down between zones either. Let it the controller run and the air rip.

    Do you agree with 100-125 CFM too?

    I believe you can use a smaller compressor to blowout a 1" 13 gpm sprinkler line.
