Customer had large root intrusion in sewer in the front yard that I recommend repairing. Was not able to get a clear inspection of he remainder of the line due to the roots and build up in the line obstructing the camera lense. Once the repair has been made includes performing further camera inspection to inspect rest of the cast iron line. Performed spot repair on customers sewer main in front yard and once we removed the section of old cast iron pipe we saw that the bottom of the drain is severely corroded and missing in some parts. Sewer main also had several other root intrusions further up the line near master bathroom. Highly recommended performing epoxy lining to the remainder of the 3” cast iron main running under the home to prevent future issues. Performing the epoxy’s lining now will allow us to replace the sewer main from the current whole without having to dig and trench inside of the home
