For this evaluation, the customers primary drain line had come loose at one of the joints. My best guess is that while I was working yesterday, I either stepped on the primary drain line or bumped it, causing that glue that was holding the PVC into the joint to come loose, and the water was dripping out of the primary drain line into the ceiling. I gave my sincere apologies to the customer and filled out a home damage report and let RYAN know what had happened.
