How roots get in

A sewer lateral carries warm, nutrient-rich water. Where a joint has loosened or a crack has opened, a little of that moisture escapes into the soil, and fine feeder roots grow toward it. Once a root tip enters the pipe it branches into a mat that catches toilet paper, grease and solids.

Older clay laterals are especially prone because they are built from short sections, each with a joint. Many La Habra neighborhoods also have decades-old street and yard trees, so the combination of many joints and mature roots is common. Plastic lines with glued joints resist roots much better, though a cracked or separated fitting can still let them in.

Clues that roots are the problem

  • Slow drains that get gradually worse over months rather than overnight
  • Backups that return a similar number of weeks after each clearing
  • Stringy fibers on the cable or in the water after the line is cleared
  • A large tree, hedge or shrub row between the house and the street
  • Symptoms that worsen in late spring and summer growth seasons

Ways to deal with roots compared

ApproachWhat it doesWhat it does not do
Cable root cuttingCuts a path through the root mass to restore flowLeave the entry point open; roots regrow
Hydro jettingScours roots and debris from the pipe wallsSeal the joints; regrowth still expected
Chemical root treatmentCan slow regrowth when applied as directedRepair cracks or offset joints; check product labels and local rules
LiningCovers joints and cracks with a continuous inner pipeFix a belly or a collapsed section
Section or full replacementRemoves the damaged pipe and its jointsStop roots attacking a new pipe if it is poorly installed

A sensible order of operations

  1. Restore flow

    Clear the line so the house can be used normally again.

  2. Inspect

    Run a camera right after clearing, when the pipe walls are visible, to count the root entry points and check for cracks.

  3. Decide on a fix

    Scattered light roots in otherwise sound pipe may be managed for a while. Heavy roots at many joints, or roots plus cracking, point toward lining or replacement.

  4. Plan around the tree

    If replacing, ask how close the trench or bursting path runs to the tree and how roots will be handled. Talk to an arborist about a valued tree.

What to ask before paying for repeated root cutting

  1. How many root entry points did the camera show, and where?
  2. Is the pipe cracked or only leaking at joints?
  3. Would lining cover all of the entry points, or are there sections it cannot fix?
  4. If I keep clearing on a schedule instead, how often do you expect to come back?

Common questions

Will cutting down the tree solve the problem?

Not right away. Roots already in the pipe stay until cleared, and the open joints remain. Fixing the pipe is the lasting solution.

Do root killers damage pipes?

Products made for sewer lines are intended to be pipe-safe when used as directed. They do not repair the openings that let roots in.

Can I plant trees over a new sewer line?

Keeping large trees away from the path of the lateral reduces future risk. Ask the plumber where the line runs before planting.
