What to Do If You Have a CIPP Liner Fail During Installation: A Guide for Australian Plumbers

Cured-In-Place Pipe (CIPP) relining has revolutionised the plumbing industry with its efficient and trenchless solutions for repairing damaged pipes. However, even the most experienced plumbers can face unexpected challenges, including liner failure during installation. If a liner failure occurs, quick action and proper steps are essential to minimise damage, reduce costs, and ensure the project’s success. Here’s a comprehensive guide for Australian plumbers on managing liner failures effectively.

Recognising the Signs of Liner Failure

Liner failures can manifest in various ways during installation, including:

• Wrinkling or buckling: The liner doesn’t sit flush against the pipe walls, creating folds or gaps.

• Inadequate curing: The liner fails to harden properly due to insufficient curing time or temperature.

• Tears or leaks: Physical damage to the liner may occur during insertion or inflation.

• Misalignment: The liner doesn’t align correctly with the host pipe, leading to compromised functionality.

Understanding these signs early allows you to address the issue promptly and mitigate further complications.

Immediate Steps to Take

When a liner failure is detected during installation, follow these steps to manage the situation:

1. Stop the Installation Process

Halting the process immediately prevents further damage to the liner or the host pipe. Assess the extent of the failure before proceeding.

2. Identify the Cause of Failure

Conduct a thorough inspection to determine the root cause of the problem. Common causes include:

• Incorrect liner measurements

• Improper preparation of the host pipe (e.g., debris, grease, or blockages)

• Inadequate curing conditions

• Equipment malfunctions

By identifying the cause, you can implement corrective measures and prevent future occurrences.

3. Remove the Damaged Liner

If the liner cannot be salvaged, carefully remove it from the pipe. This process may involve cutting and extracting the liner, so use appropriate tools and techniques to avoid damaging the host pipe.

4. Communicate with Stakeholders

Inform your client and team members about the issue. Be transparent about the failure, its cause, and the steps you’re taking to resolve it. Clear communication helps maintain trust and professionalism.

5. Prepare the Pipe for Reinstallation

Thoroughly clean and inspect the host pipe to ensure it is ready for a new liner. Address any contributing factors, such as improper cleaning or blockages, before proceeding.

Preventing Liner Failures

While liner failures can sometimes be unavoidable, taking proactive measures can significantly reduce their likelihood. Here are some best practices:

1. Ensure Accurate Measurements

Precise measurements of the host pipe’s dimensions are critical. Use advanced inspection tools, such as CCTV cameras, to obtain accurate data.

2. Thoroughly Clean the Host Pipe

Proper cleaning and preparation are essential for successful liner adhesion. Use high-pressure water jetting or mechanical cleaning to remove debris and ensure a smooth surface.

3. Verify Equipment Functionality

Regularly inspect and maintain all CIPP equipment, including curing systems and liner installation tools. Address any malfunctions before starting a project.

4. Monitor Curing Conditions

Follow the manufacturer’s guidelines for curing temperature, time, and pressure. Consistent monitoring during the curing process ensures the liner sets correctly.

5. Invest in Quality Materials

Use high-quality liners and resins from reputable suppliers. Inferior materials increase the risk of failure and can compromise the project’s long-term success.

Partnering for Success

Liner failures, while challenging, can be managed effectively with the right approach. By following best practices and investing in quality equipment and materials, Australian plumbers can minimise the risk of installation issues and deliver reliable, long-lasting solutions.
