I am not familiar with using expansion joints, so I am hoping the more experienced plumbers here could enlighten me:
1) Are they used to guard against movement in the ground, roof, or both?
2) Where are they placed...at the bottom of a stack?
3) Should every stack have an expansion joint?
Thanks for any info you guys can provide.
