Tree roots can enter sewer pipes in a number of ways, and it’s important to understand these entry points in order to prevent root blockages. Here are ten common ways that tree roots can enter sewer pipes:

  1. Cracks in the pipes: Over time, earthenware pipes can develop small cracks and fissures that allow tree roots to penetrate the pipes and grow inside.
  2. Loose joints: Joints between sewer pipes can become loose, allowing roots to penetrate the gaps and grow into the pipes.
  3. Open seams: Some earthenware pipes are made of multiple sections that are joined together. If the seams between these sections are open or damaged, tree roots can enter and grow inside.
  4. Pipe misalignment: If the sewer pipes are not properly aligned, gaps can form between the pipes and the surrounding soil, allowing roots to penetrate the gaps and grow inside.
  5. Pipe corrosion: Over time, earthenware pipes can corrode and weaken, making them more susceptible to root penetration.
  6. Deteriorating pipe material: If the earthenware pipes are old and deteriorating, tree roots can easily penetrate the weakened material.
  7. Nearby tree or shrub roots: If there are trees or shrubs growing near the sewer pipes, their roots can extend into the pipes and cause blockages.
  8. Root-seeking moisture: Sewer pipes can provide a source of moisture that tree roots seek out in dry or drought-prone areas.
  9. Tree species: Some tree species, such as willows, cottonwoods, and silver maples, are particularly aggressive in their search for moisture and nutrients, and their roots can easily penetrate sewer pipes.
  10. Poor installation: If the sewer pipes were not properly installed in the first place, they may be more susceptible to root penetration and subsequent blockages.

Preventing tree roots from entering sewer pipes can be challenging, but it’s important to take proactive measures to avoid costly blockages and repairs. Regular maintenance, proper installation, and the use of root control solutions like Sanafoam Vaporooter can all help to keep tree roots out of sewer pipes.
