For this job, the customer was having problems her toilet and shower not draining properly. Confirming that it was not a vent issue, we pulled the toilet out and ran the camera into the drain and found the blockage. We also noticed the main Drain had fingers inside. Running the drain machine, we was able to break loose the blockage. Setting the toilet back in place we ran the water and did not have any backfill. Also, recommend getting new drain system, the drain is an old galvanized system. Customer want us to give her a quote and give her a call As of right now, we did not find any any other issues with the toilet.
