We are in the process of finishing up a basement apartment. Unfortunately the PVC waste pipes are right above the dropped ceiling in the bedroom. Any good ideas on how to smother or quiet the noise when flushing a toilet upstairs or running water?
You could insulate them. While it's not NEEDED the foamy stuff that's used should quiet the noise at least a bit.
It may be cheaper to buy foam from the craft store & then duct-tape it...but I've never compared prices so I suggest you do before taking this last bit of advice ;)
