I just recently noticed a vibrating water pipe under the drywall
ceiling of my partially finished basement. It vibrates when the first
floor toilet is flushed and the kitchen sink turns off. The previous
owner finished the basement and I assume the pipes are leaning directly
against the drywall since the pipes go right along the edge of the
beams in the unfinished part of the basement. Is this a problem? I
don't notice any of the other pipes in the basement vibrating when
water is turned off. Is there a way I can minimize the vibration
without cutting open the cieling?


A valve can create a vibration. Commodes have valves with small orifices
which are vibration prone. Try replacing the valve in the tank in that
commode.
