    I'm a pvc guy, also, but use poly for potable hook-ups. I only use 160/200 psi depending on the soil conditions, that way I can use pack-joints and tees.

    Any modern poly tubing will have a 100 psi rating, if it is the same thickness as yesteryear's 80 psi tubing. Utility poly isn't getting any abusive use from me - a high static pressure that might find its way to a mainline means a mainline upgrade to 125 psi or higher.

    I never gave a rat about psi ratings, the soil conditions dictated the choice of pipe. :)

    Pulling with a Piper made it difficult to switch to 160, since the King Grips we used were matched to tubing OD

    One of my techs called this afternoon from a job. 155 psi on the pvc mainline. Had a hairline crack in the pvc. Older system, class 200.
