I removed all the metal hanger straps that supported any pipe and replaced them with plastic hanger straps.

metal vs. plastic hanger straps
The plumbing drain stack was originally strapped tightly to the studs in the wall from the basement all the way through to the attic. Unfortunately, changes in water temperature and the weight of the water, caused the PVC pipe to expand, move and rub against wood studs, resulting in creaking sounds. The plastic straps are more flexible than the metal straps, so hopefully it would give more with the PVC plumbing.
I also suspended the pipes between the studs of the wet wall. Fortunately we have 2 walls (or a wet wall) which the pipes run between, so every other strap was attached to alternating wall studs. This way, the PVC would not directly touch the wood. A little complicated I know, but hopefully this arrangement will pay off.
