    Water hammer on metal pipe is annoying and can get loud. On a rare
    occasion it can cause a pipe fracture.

    But water hammer on PEX is much worse. If someone is walking under
    one of the PEX pipes in the basement, they could die due to the water
    hammer. If the water hammer is severe, those flimsy PEX pipes can
    start to whip around at an extremely high speed. The greater the
    water pressure, the higher the torque of the whipping pipes. It's not
    uncommon for a water hammer episode to get these PEX pipes whipping so
    harshly and forceful that they literally shatter several 2x10 floor
    joists, doing serious structural damage to the building, and even
    tearing holes right thru the floor above the pipes. The next thing
    there is furniture falling thru the floor into the basement, and
    heaven forbid a young child is sleeping above these pipes in their
    crib.

    Now imagine this. You or a family member are walking thru the
    basement when someone flushes a toilet. Seconds later these PEX pipes
    begin whipping around the basement knocking down heating ducts,
    ripping out wiring, and damaging floor joists. Worse yet, YOU are
    directly under these plastic pipes and you become decapitated and.or
    lose other limbs from your body. Although the PEX industry has put a
    hush on hundreds of PEX related deaths, the word has leaked out and
    this news is quickly spreading. PEX KILLS !!!!

    I'd recomment placing a water hammer arrestor every six inches along
    all runs of PEX pipe. The life you save may be your own, or another
    family member.


    SAFETY FIRST (or shortly after you get drunk).

    This is the truth, the whole truth, and nothing but the truth, so help
    me God.

    The PEX industry has been hiding this truth from the public much too
    long. Have you ever seen a garden hose get out of control, and begin
    whipping around? It's similar to that, but much worse, when water
    hammer is involved. How many more lives will die before this truth is
    revealed? It's all about money, profits, and greed. The PEX industry
    don't care how many die, as long as their bank accounts are being
    filled with your money, the money from persons who may soon meet their
    demise due to this faulty product. PEX kills. While the government
    is busy taking away substances in our lives that might harm our
    health, such as cigarettes, alcohol, and narcotics, nothing is being
    done about PEX, a product that can kill instantly. A product that can
    decapitate a large adult person in less than one second, simply
    because someone else in the home flushed a toilet.

    Once those pipes begin whipping around, and their fastners break
    loose, the result is far more devastating than most people experienced
    during hurricane Katrina. Entire PEX plumbing systems have become
    dislodged from a building's structure within seconds, and gotten out
    of control, destroying and/or killing everything in it's path. Once
    this occurs, there is no stopping this monster, unless the water can
    be turned off at the curb, or one of the pipes finally breaks, and at
    that point the devastation stops as the PEX pipes get limp and
    retract.

    PEX Kills !!!
    You have been warned.......

    You will have to don your PEX resistant body armor
    and helmet before you work on your plumbing soon.
    It's my understanding that it is a pending OSHA
    rule that will soon be enacted. There is already
    a fart absorbing undergarment on the market that
    will also be required by OSHA on all construction
    sites, especially where there are open flames.
