Cured-in-place pipe lining (CIPP) is an effective solution for fixing a damaged sewer line. This pipe repair method involves inserting a resin-saturated felt pipe into the damaged pipe. The resin dries and hardens to form a new pipe inside the damaged one. The entire process is completed without digging out the old pipe; thus, it is non-disruptive to landscaping. This repair method significantly increases the lifespan of the old sewer line. However, the longevity and performance of the lining solutions depend on the factors below.

Viability of the Project

Cured-in-place pipe lining solutions are effective in repairing damaged sewer lines. However, they are not suitable for all forms of damage. If you use pipe liners to fix severe damage, they won't work. Instead, your sewer line will develop issues down the road, leading to a costly replacement. Below are two instances where CIPP solutions may not work for you. 

Severe damage and corrosion

Pipe liners can fix minor-to-moderate damage caused by tree roots and age-related corrosion. The integrity of the original pipes determines the performance of the liners. If the pipe is severely broken or corroded, the liner won't be able to adhere to it correctly. As a result, the new piping will fail shortly after repairs. Therefore, go for CIPP solutions only if your sewer line is structurally sound. 

Sagging or collapsed pipe sections

Has your sewer line collapsed due to ground movement or poor installation? Are there sagging sections along the system? If so, you cannot use relining solutions to level the piping. While pipe liners may strengthen the sewer pipes, they won't solve problems caused by sagging. For example, the sagging sections may still impede wastewater flow. Therefore, level the sewer line before using relining solutions to repair the pipes.

 Preparation for the Installation

Proper preparation is crucial to improving the performance of cured-in-place pipe lining solutions. Therefore, you must carry out the following steps before repairing the old sewer line: 

  • Inspect the sewer line: A video camera inspection will reveal the sewer line's condition, spot breakages and obstructions, and determine the viability of CIPP solutions for pipe repairs.
  • Clean the pipes: After determining that the sewer line can be repaired using pipe liners and resin, clean the pipes using highly pressurized water. The water will clear out debris from the walls of the pipe to create a smooth surface for the pipe liner to adhere to. 

Skipping the above steps may affect the performance and durability of your relined pipes. For example, failure to scan the pipes using a video camera may lead you to use lining products on a severely damaged sewer line. As a result, the repairs won't last as long as you had expected.

Consider these issues when using cured-in-place pipe lining installation services. For further consultation and pipe relining services, contact a plumbing contractor.
