San Francisco’s beautiful mature trees can wreak havoc on your sewer lines. Tree root intrusion is one of the most common—and most destructive—sewer problems we see. Here’s what every SF homeowner should know.
How Roots Get Into Sewer Lines
Tree roots are naturally drawn to the moisture and nutrients inside sewer pipes. They can sense these resources through tiny cracks or joints in the pipe and will grow toward them. Once a small root finds its way in, it grows and expands, eventually causing major blockages and pipe damage.
Signs of Root Intrusion
- Slow drains throughout the house
- Gurgling sounds from toilets
- Frequent sewer backups
- Patches of extra-green grass over the sewer line
- Sinkholes or wet spots in the yard
- Foul odors near the sewer line
Why San Francisco Is Especially Vulnerable
Many San Francisco homes have older clay or cast iron sewer pipes that are more susceptible to root intrusion. The city’s many established trees, combined with aging infrastructure, creates perfect conditions for root problems.
Treatment Options
Rooter Service
A professional rooter machine uses spinning cutting blades to slice through roots and restore flow. This is often the first step in addressing root problems.
Hydro Jetting
High-pressure water jetting clears remaining root fragments and debris after cutting, thoroughly cleaning the pipe.
Pipe Lining
For long-term prevention, trenchless pipe lining creates a new pipe inside your existing one, sealing cracks and preventing future root entry.
Pipe Replacement
Severely damaged pipes may require replacement. Modern trenchless methods can often accomplish this with minimal digging.
Prevention Is Key
Annual camera inspections can catch root problems early, before they cause backups or pipe damage. If you have large trees near your sewer line, regular monitoring is essential.
