This morning I was on the first floor while my wife was washing up on the second. The pipes were pretty noisy; more than I remember hearing before.
This concerns me because 2 years ago I replaced some ceiling tiles in the basement and found that a 20' run of pipes had pulled free of all the pipe hangers and was just shaking around. I reinstalled better hangers and it seems fine, but it worries me about the plumbing quality in general.
I don't know much about plumbing, but presumably the pipes upstairs run though holes in joist and can't move around much?
Should I be concerned about the noise? Is there anything, other than ripping up the floors and walls, to be done about this?
