    Default Dishwasher install leads to water hammer

    Dishwasher install leads to water hammer.

    Some codes like the UPC, require hammer arrestors on devices that have quick closing valves.
    In a home, that would be
    Ice Maker
    Dishwasher
    Washing Machine

    I've also installed them in commercial bathrooms that use Flushometers.
    Why have constant banging pipes if it can be avoided?

    I have had a lot more flush valves cause "water hammer" when they start to flush, which an arrestor will not prevent, than when they shut off.
