Yes I have.
And others have too. That's why the plumbing code "requires" hammer arrestors for them. Whenever I install water to an icemaker, I use the box with the hammer arrestor.
I guess you've never heard an icemaker filling before. Yes, I notice.
I heard from a Boeing Engineer that was being woken up throughout the night by his icemaker.
I tried to explain to him that he needed to install a hammer arrestor for that, and even gave him one to install. It sat in a drawer until his father-in-law came over and installed it for him. The FIL was a plumber, and knew what it was for. Anyway, my friend now sleeps through the night. Sometimes you need to lead those engineers through things. Books and codes don't mean much. They have to discover simple things like water hammer on their own.
