    I see everyone suggesting PVC for irrigation. Why is poly taboo? My system has poly but that was before I met you guys :) Seriously though, most contractors, if not all in my area, use poly.

    99% of what we install is poly.....faster and easier than pvc....

    Larger commercial and golf cousre stuff we do in pvc.. but that just because of the psi rating

    Not a thing wrong with poly, for residential and light commercial under 1 1/2". It's commonly used and easier to repair.

    I only wish we could use a vibratory plow and poly pipe. The soil is so hard, and so filled with shale and rock that a plow and poly pipe would be slower than a trencher or backhoe. Thus, we use PVC.

    Use nothing but poly pipe here, except for the mainline which I build with pvc. There is nothing wrong with poly pipe and is the only way to go with pulling it in with a vibatory plow. Seems different areas have different prefences and different soil conditions, if you used a trencher in my area and left the established yard a mass of stripes when you were done, you would be done and very lonely!!

    For some reason here in Pittsburgh, Poly is not used. Out of hundreds of systems that I service, I may have 2 or 3 Poly systems.

    Theres nothing wrong with poly. Poly is a lot stronger than pvc when it comes to frezzing under ground. It isn't as brittel like pvc can be.

    Either is fine.
    We use PVC and pull it in with a vibratory plow, and it seems to have worked well for us the past 5 years.
