I have water hammer and I am trying to understand it better. Thanks to those who have helped me already.
I have reviewed everything I can find on water hammer including the last two years of this wonderful site.
My 2 questions are:
if water hammer is caused by air trapped in the pipes, how does the air get there? I know when repairs are done, air will be in the pipes until it is expelled through a faucet valve or whatever. After that, shouldn't the system stay closed with no air getting in?
Could I have some problem which is causing air to get into the plumbing system?
I am working with the plumbing contractor who built my home. We have already added arrestors and a new pressure reducer valve. I still have water hammer.
We still need to check the for faulty washers.
