Why roots end up in the line
A sewer lateral carries warm, nutrient-rich water. Older clay pipe was laid in short sections joined every few feet, and those joints, along with cracks in clay or corroded cast iron, let a little moisture escape into the soil. Nearby roots follow that moisture, slip in through the gap and spread into a fine mat inside the pipe.
The mat catches paper and grease, the opening narrows, and eventually the line backs up. Many of Anaheim's older tract streets have decades-old trees in parkways and yards, which is why root clogs come up so often in homes from that era.
Signs roots may be involved
Clearing roots versus fixing the entry point
Cutting and cleaning
- Restores flow quickly with a cable cutter or jetter
- Usually less disruptive in the short term
- Does nothing to close the joint or crack
- Roots typically regrow, so it becomes recurring maintenance
Repairing the pipe
- Spot repair, lining or replacing the damaged section
- Aims to close the opening roots use
- More planning, and sometimes permits and excavation
- Decision should follow a camera inspection
How a root problem usually develops
- Early
- Fine roots enter a joint. Drains seem normal, though flow may slow slightly.
- Building
- The root mat thickens and starts catching paper. Occasional gurgling and slow drains.
- Blockage
- The line closes enough to back up into the lowest fixture, often the tub or a floor drain.
- After cutting
- Flow returns. The same roots regrow from the joint unless the opening is repaired.
What to ask after a root clog
- How far from the cleanout are the roots, and is there one entry point or several?
- Is the pipe cracked or just leaking at a joint?
- Is the root location on my property or close to where the city's responsibility begins? Check with the city for the exact boundary.
- What are the repair options for that section, and do any need a permit?
- If I choose maintenance cleaning, how will we know when repair makes more sense?
Common questions
Will removing the tree solve the problem?
Not on its own. Other roots can find the same opening, and removing a tree can have its own costs and rules. Closing the gap in the pipe is what stops the intrusion.
Do root-killing products work?
Some products are marketed to slow root regrowth inside pipes. Ask a licensed plumber whether one is appropriate for your pipe, and follow the label exactly. They do not repair the opening.
Can plastic sewer pipe get roots?
It is much more resistant because its joints are glued or sealed, but roots can still enter where pipe is damaged or where plastic connects to an older section.
