Pride Plumbing was called out for sewage backing up into a double sink bathroom vanity. We went underneath the home, separated a PVC and cast iron drain line, and used a sewer machine in an attempt to clear the blockage. The cast iron drain line was very corroded, so we couldn't get the drainage we wanted, but were able to get them to slowly drain. We also provided a cost estimate to replace the drain lines for the double bathroom sink vanity through the floor and tie-in to the PVC drain line underneath the home, add an air admittance valve underneath the bathroom sink cabinet, and replace a bathtub/shower drain.
