The house does not have copper pipe - all of the supply lines are grey PVC.


Not all plastic is PVC and gray colored PVC is more commonly found in UV
resistant electrical conduit. In other words, before cutting and capping, make
sure that your pipes are PVC, CPVC, PEX, ABS or whatever and apply the correct
cleaner and solvent cement. Materials are often identified on the pipe itself
with markings every foot or so. Look for the ID and choose the right repair
system and you should have an easy fix. Good luck.
