How Long Does Pipe Relining Take?

Pipe relining has revolutionised the way we repair damaged pipes. Unlike traditional methods, which often involve extensive excavation, pipe relining is a trenchless technology that offers a quicker, less disruptive solution.

One of the most common questions homeowners and businesses have about pipe relining is: “How long does it take?” The answer can vary depending on several factors, but this blog will provide a comprehensive overview of the typical timeline for a pipe relining project.

1. Initial Inspection and Cleaning

Time: 1-2 hours

The first step in any pipe relining project is a thorough inspection of the existing pipes. Plumbers use advanced CCTV camera technology to inspect the interior of the pipes, assess the extent of the damage, and determine if pipe relining is a suitable solution. This inspection is crucial as it helps identify any blockages, cracks, or structural issues that need to be addressed.

Once the inspection is complete, the pipes must be cleaned to ensure the lining adheres properly. High-pressure water jetting is commonly used to remove debris, grease, and other buildup from the pipes. This step is essential to creating a clean surface for the liner.

What to Expect:

Inspection: A detailed view of the pipe’s condition.
Cleaning: Removal of any debris or buildup that could interfere with the relining process.

2. Pipe Preparation

Time: 1-2 hours

After the inspection and cleaning, the next step is to prepare the pipe for the relining process. This involves measuring the pipe’s length and diameter to ensure the liner fits perfectly. The plumber will then cut the liner to the appropriate size and apply a resin coating. In some cases, additional access points may need to be created to insert the liner, especially if the pipe is long or has complex bends.

What to Expect:

Preparation: Customising the liner to fit the specific dimensions of your pipe.
Access Points: Creating entry points if necessary for liner installation.

3. Liner Installation

Time: 1-2 hours

With the pipe prepared, the next step is the installation of the resin-coated liner. There are different methods for inserting the liner into the pipe, including inversion (using air or water pressure to push the liner through the pipe) or pulling the liner into place. Once inside, the liner is inflated so that it presses against the walls of the existing pipe.

What to Expect:

Insertion: The liner is carefully placed into the pipe.
Inflation: The liner is expanded to fit snugly against the pipe walls.

4. Curing the Liner

Time: 2-24 hours

After the liner is in place, the resin needs to be cured to harden and form a durable new pipe within the old one. The curing process can vary depending on the type of resin used, the pipe’s size, and environmental factors such as temperature and humidity. Curing methods include using hot water, steam, or even ultraviolet (UV) light.

What to Expect:

Curing: The resin hardens, creating a strong, seamless pipe within the old one.
Time Variance: Curing time can range from a couple of hours to a full day, depending on the specifics of the project.

5. Final Inspection

Time: 1-2 hours

Once the liner has cured, a final inspection is conducted using the CCTV camera to ensure that the relining process was successful. The plumber will check for any defects in the new lining and verify that the pipe is functioning properly. This inspection is crucial as it confirms the quality of the work and the effectiveness of the repair.

What to Expect:

Inspection: A final check to ensure the pipe relining was done correctly.
Verification: Confirmation that the pipe is ready for regular use.

Total Time Estimate

In total, a typical pipe relining project can take anywhere from a few hours to a couple of days. The exact duration will depend on factors such as the length and diameter of the pipe, the severity of the damage, and the chosen curing method. For example, smaller pipes that are easily accessible might be completed in a single day, while larger or more complex projects could extend to two days.

Factors Influencing the Duration of Pipe Relining

Several factors can impact the overall time required for a pipe relining project:

Extent of Damage: Pipes with extensive damage or multiple blockages may require additional time for preparation and relining.
Pipe Material: Some materials may require different curing techniques, affecting the time needed.
Access and Location: Pipes that are difficult to access or located in challenging areas may take longer to prepare and reline.
Weather Conditions: Extreme temperatures or humidity can influence the curing time of the resin.

Conclusion

Pipe relining is a highly efficient and minimally invasive solution for repairing damaged pipes. While the time it takes can vary depending on the specifics of your project, most pipe relining jobs can be completed within a day or two. This quick turnaround, combined with the long-lasting benefits of relining, makes it an attractive option for homeowners and businesses facing plumbing issues.
