how do i get rid of joint compound in our water after plumbing repairs?
Answers:
Joint compound is used to smooth between sections of drywall, I can't think of a use in plumbing.
If it's pipe dope (threaded pipe), cement (PVC), or solder (copper), just open the taps full force for 5-10 minutes, should flush out fine.
Other answers:
Just run the water for a few minutes.
