In this area, we find that problem at least once a week. It happens because the installing plumbers use a MIP adapter which is one of the weakest fittings in the plumbing trade and it cracks from the slightest stress. We repair it by using a Sch 8 PVC, or brass, nipple and dresser coupling. The break can occur at either end of the PVC, but have seldom had both ends break.
