Foothill homes and root intrusion

Monrovia's foothill neighborhoods have big, established trees, and their roots find their way into older sewer laterals. The sign is a drain that backs up, gets cleared and backs up again. We put a camera in the line to find the entry point, then clear it with hydro jetting and recommend a repair that stops the cycle. Tree roots in the sewer line.
