When I went to turn on my exterior faucet this spring it flooded one of my bedrooms. I guess the pipe burst during the winter and when I opened it up in the spring it flooded.
Anyways, I've replaced the faucet with a new frost free faucet. The problem is since I've replaced it, every time I turn the water on out front there is some very bad water hammer. It only happens when I use that front faucet i replaced. Once the valve gets opened fully it stops, but during turns 2-4 its shaking the entire house. How do I fix this? Why would it only be on that one faucet?

edit: also, everything I read on water hammer refers to when the water is shut off suddenly. In my case its happening when I turn the water on.

 

If it only happens when you turn on the faucet, it isn't water hammer. Have you checked to make sure the pipe is properly secured? The suddent force of water through the pipes could cause the pipe to vibrate

 

Well, Its supported by an exterior stud just behind the siding. Then it 90 degrees down to the concrete. So from the floor to the wall there's really nothing to secure it to. The wife said she can hear the entire kitchen shake (opposite side of the house) so thats what made me think of water hammer, because it acts like there's air in the system. I guess it could be vibrating in the floor. When you have a slab house do they just pour the concrete on the pipes? or do they put the copper in pvc to protect them before they pour the concrete?

also, the faucet i replaced was longer than the existing one. So I had to remove a lil before I soldered the sleeve. But the overall length didnt change, and it never did this before.

 

Honestly for the speed and low aggravation of just getting a different faucet and putting it on, that's the route I would go. Instead of re-engineering your house to accommodate a 5 dollar spout, just get a different one. Inside the house somewhere before that line goes outside put a shut off valve in line and just turn the water off to that spout in the winter.
