Why roots find clay pipe

Vitrified clay pipe itself is very durable, but it is laid in short sections joined together. Over decades, those joints shift and open slightly. Warm wastewater leaks a little moisture into the soil, and tree roots follow it into the joint. Once inside, roots grow into a mat that catches paper and debris until the line blocks.

Why snaking alone keeps failing

A basic drain snake can punch a hole through a root mass and get water flowing again, but it leaves most of the roots attached to the pipe wall. They grow back, often thicker. Full-width cutting heads or root-cutting jetter nozzles clear the whole pipe diameter, which usually buys much more time between problems. A camera inspection afterward confirms the line is actually clean.

When it is time for a longer-term fix

If roots return quickly or the camera shows cracked or offset joints, repeated cleaning may cost more over time than a repair. Trenchless pipe lining creates a jointless pipe inside the old one, which removes the gaps roots use. Ask the contractor to walk you through both options with the camera footage in front of you.

Roots and Ontario's older neighborhoods

Ontario was planned around trees. Euclid Avenue, laid out in 1882 by George and William Chaffey, still has a median planted with California pepper trees, deodar cedars and palms, and mature silk oaks line both sides of the historic district. Many streets in the older parts of the city have large, established trees near homes built in the 1950s and earlier, which is exactly where clay and cast-iron laterals are most likely.

If the roots in your line come from a City street tree, the City of Ontario asks residents to report it to the City of Ontario Municipal Utilities Company.

Who owns which part of the pipe? The City of Ontario maintains the part of your sewer lateral that sits in the public right-of-way (under the sidewalk, parkway or street). The part on your property is the owner's responsibility. If you are unsure where a problem is, the city suggests checking with its Municipal Utilities Company before you sign a repair contract.
What to expect

How it usually goes

Locate the root entry points

A camera shows which joints roots are coming through and how far they have grown.

Cut and flush

Rotating root cutters or a root-cutting jetter nozzle remove roots across the full pipe wall, then the line is flushed.

Plan the fix

The contractor explains whether regular maintenance is enough or whether lining or repair would stop roots for good.

Questions

Clay Pipe Root Removal FAQ

How often do roots grow back after cutting?

It varies with the tree, the pipe and the condition of the joints. A camera inspection after cleaning is the best way to judge it, and the contractor can suggest a maintenance interval for your line.

Can I just cut down the tree?

Removing a tree does not remove the roots already inside the pipe, and the joints roots used stay open. The line still needs to be cleared and checked.

Is hydro jetting or a cutter better for roots?

Both can work. Cutters are strong on heavy root masses; jetting with a root-cutting nozzle also scours the pipe walls. Many contractors use a combination depending on what the camera shows.
