Water pipes knocking on upper floor, after pipes burst
Hi - recently, my water pipes froze and burst, flooding my basement. I've had the pipes repaired.
Now, when I turn on the hot water in my upstairs (2nd floor) sink, there's a knocking/clunking after I turn the hot water off. Its only the hot water (doesn't do it with cold water).
When I turn the hot water off, the knocking is faster, and it occurs in more than one place in the bathroom, but it slows down. (so, its: knock-knock-knock... knock... knock... knock, etc).
Would this be water hammer? Its not super loud. I'm just a little worried that some damage has been done upstairs because of the frozen pipes. There's no indication of additional water damage in the house beyond what's clearly because of the burst pipes.
Any ideas?
