Customer noticed water coming out of the wall at the floor then noticed over head in the kitchen the paint was bubbling out they said they noticed it would get worse when they would use the master bath lavatory faucet so I opened the wall underneath the faucet in the restroom on the 2nd floor and didn’t see any breaks in the drain so with my moisture meter I climbed up my ladder in the kitchen and put it on the ceiling and located the most wet spo of drywall and opened the ceiling there and found a 2” drain pipe cracked completely in half. Going to do the repair today.
