    Shavings only occur if you're irresponsible and careless.
    On the exhaust, it's a non issue.

    Sawzall has been my tool of choice since they brought in the scam of 636.

    My buddy works for Royal pipe systems, he's got it on good authority that 636 is the same as sched 40 pvc but twice as expensive because its "certified"

    I have seen several PVC installs where after a couple if years you can see it deform and sag between supports. I have never seen this with a 636 system.

    The other difference with 636 is that the bonding agent is not a glue, but a cement that melts and bonds the 2 pieces of plastic together.
    We see many a pvc fitting where the glue has started to let go and condensation has started to drip from the joints

    The only joint compound I have ever used on PVC is a solvent joint, rather than a glue.

    I can't remember ever seeing a glue joint on PVC.

    Of course, they use a glue on ABS, but I never see that in the states.

    The leaking from the joints is from improper preparation. If you don't chamfer the edge of the pipe it scrapes out the solvent from the socket of the fitting.

    Like timebuilder said, all PVC is assembled with solvent cement, not glue.

    PVC "Glue" is actually solvent cement. The same type of bonding agent that you're referring to with 636 piping.

    Done properly, PVC joints are as permanent as it gets.

    Well correct me when im wrong! Thanks for the clarification. So to go a little further, the black pipe with yellow solvent is.. Ie the stuff that was used in Canada for hi eff systems before 636.
    I know I've read the labeling before but it escapes me at the moment.

    How many turns around to cut 3"? How hard is it to both hold and cut at the same time or do you clamp the pipe down?

    The cutters big enough for 3" pipe are a bore to handle. That being said, the right wheel makes a huge difference, and they make a really clean cut, but its still a bit of a fight
