    Only a hack would use poly for main. Don't even think about it.

    i always use a master valve.
    i have not pulled much pvc.
    fastest process would be pull all 1 inch for anything more than 8gpm. from valve to furthest head. then pull close, single heads to the " with 1/2" blu loc pipe or 3/4 poly. use blazing saddle tees with blu-loc 1/2" male adapters and blulock combo elbows for the heads.
    pay more for the blu-loc fittings and pipe but saves on labour. dig smaller holes and compression fittings.
    What I do is run 3/4"poly and split it with 1" then use blu-lock where it is suitable

    Yes, I get irritated working on other peoples junk. Whenever I see a poly main, it's sure to be a long day.:hammerhead:

    What difference does it make using poly for a main line?
    PVC from PVB down to 10" deep, generally PVC to first manifold if it's within a few feet, then if there is going to be another manifold further away, it's poly.
    Clamp it good, don't see what the deal is. OTH, I'm only dealing with 60 psi max. too, so with higher pressures, I could possibly see it.
    Speaking for 1" lines.

    Makes no difference, all systems are alike and installed correctly.:)

    I am a pvc pro not a poly pro, but having a master valve basically makes the main a lateral right? At least until a solenoid fails or a wire gets cut. What do you pull for a main line?

    Here in Ontario. My city has about 20 irrigation companies. Not one, uses pvc for anything unless its a commercial job over 1 1/4".
    If anyone tried selling pvc systems here they would not win any jobs.
    No licensing, no backflow requirements.
    Everyone here uses dual check valves as a backflow.
    Laws are no where near to what they should be
