Re: water hammer when faucet is turned on
What is your static water pressure -- the pressure in the system when no water is flowing? (You can measure this with a gauge that connects to a garden hose faucet.) If it's too high (>80PSI) that can cause the issue; the transfer valve in the faucet may not function correctly under high pressure.

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
