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?

Water Hammer Arrestors

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.
