Im replacing laundry tub, sink faucets and washing machine bibs. There are 8" copper air chambers soldered into the line. I doubt they are doing anything for me but I do not have a water hammer problem so maybe they do work as intended.
Should I add air chambers again or add a tee with hammer arrestors to the new piping? Or should I avoid that extra work/expense and wait and see if I have a problem and then add them at the supply lines if neccessary?

Put it this way, are hammer arrestors at a washer a code requirement?

The air chambers are not doing anything. After a short time they just fill with water. It was a good idea but didn't work - just like my first 5 marriages.....
I've installed a fair amount of the Sioux Chief water hammer arresters. Usually at the shut off valve or on the back of the machine.

To the best of my knowledge they are not a code requirement in California for washing machines.

Not sure,brought it up with a few other Plumbers and they said all the inspectors want to see them now.I'm going to make a few calls next week to see what the story is.I'll tell you I'm not a fan of those tiny (at the fixture) arrestors so for a few years we have been installing the ( Sioux Chief 652-as ) Press/sweat entry level commercial hammer arrestors inside the walls for washing machines and shower valves with great success.
