Clear mainline blockage through exterior cleanout Customer called us for a mainline issue affecting whole house. Upon arrival we opened the clean out cap and we had sewage water come out. Customer attempted to clear blockage and was unsuccessful, and we got approval to to perform work. We ran k400 cable machine to attempt to clear blockage, after various attempts we were able to clear blockage. Upon bringing the cable back we noticed soft tissue and a broken piece of pvc. We notified customer of the pvc piece. Customer has an appointment with a sewer supervisor to further investigate today from 12-3.
