Is Trenchless Pipe Lining Always the Best Choice? Situations Where It’s Not Ideal

Pipe lining is often viewed as a reliable solution for aging or damaged sewer lines. At Bell Plumbing, we have used this method effectively in many homes. Still, there are certain situations where it may not be the most suitable option. Homeowners considering trenchless sewer repair in Belmont, CA benefit from knowing when alternative approaches should be discussed before making a decision.

When Pipe Lining Cannot Fix Severe Structural Damage

Trenchless pipe lining is effective when existing pipes are stable enough to hold the liner. If the pipe has collapsed sections or has shifted significantly, the liner has no structure to bond with. In such cases, replacement methods provide a stronger long-term fix. Severe structural damage often requires trenchless pipe replacement rather than lining.

Pipes That Are Too Small or Improperly Sloped

If a pipe is already undersized for a household’s needs, lining slightly reduces its diameter even further. This can cause recurring drainage issues. Similarly, if the pipe slope is inadequate, there’s no way for pipe lining to correct the angle. These conditions typically call for trenchless sewer replacement or another corrective measure. Addressing slope or sizing concerns during installation is more effective than attempting to line pipes that are not functioning correctly.

Extensive Corrosion or Soil Conditions

Pipes with heavy corrosion may not have enough integrity left for a liner to adhere properly. The risk of failure is higher when the original surface is unstable. Additionally, certain soil conditions put extra pressure on weakened pipes, increasing the likelihood of collapse after trenchless pipe repair. In those cases, using other techniques may be more reliable and provide longer-lasting results.

Short Pipe Sections or Improper Access Points

Trenchless pipe lining requires sufficient access to the damaged section. If the issue lies in a short section near a bend, or if access points cannot be created safely, lining may not be practical. Traditional approaches are often better suited in these situations, as they allow for targeted repairs without relying on full-length liners.
