Hi all,
I'm new to the forum and found it by searching for code information on Water hammer arrestors.
I understand what the arrestors are and how they work but I haven't been able to find if and where code requires them. Some one told me they were required on every fixture but I find that hard to believe. I'm helping a friend remodel her bathroom and I notice the the old plumbing had the old school air chambers (not much good, I understand) and the newer master bath had none installed at all.
Are they required in bathroom fittings or only at quick closing valves?
Thanks,
John
