|In response to Re: water hammer - why air in pipes?|
: : 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.
: : Thanks,
: : Debbie
