Just by curiosity, how many of you are still putting air chambers or stub out in?
I heard they are completely illegal in California now. Is it true?
We are suppose to use water hammer arrestor now instead on dishwasher and laundry machine.
Are you putting them on sink and toilet too?

Not true.
San Francisco(The City That Knows How) still requires them.
The 2013 Ca Plbg Code has dropped air chambers as an approved method for hammer arresting and states only mechanical arrestors.

Water champers for water hammer are useless, they become water logged in a few short weeks. Dead ends on water piping "longer than 6" are against the code(in my state), Stagnant water...yuck.

I know that 2013 UPC completely removed them and after reading this [en.sarblogs.com], I am kind of confused.
I used to put air chambers everywhere.
Would it be wrong to just put water hammer arrestor everywhere now like on bathroom and kitchen sing in addition to shower valve, CW and dishwasher?
Do you know if Marin County still requires them? I tried to reach the inspector but no luck. I would hate to fail my next inspection because I put arrester instead of air chamber or didn t put anything.

Enforced codes, from Marin County's website -
"(5) The 2013 edition of the California Plumbing Code, known as California Code of Regulations, Part 5 of Title-24, incorporating the 2012 edition of the "Uniform Plumbing Code" as published by the International Association of Plumbing and Mechanical Officials, including Appendices A, B, G and I, with exceptions, additions, and deletions as provided in this title.
If the job is in a city, you should check with the city to see if there are amendments to the CA codes.
