Steps to replace a damaged pipe section

A damaged section of pipe can cause leaks, reduce water pressure and cause major damage if not replaced in time. Whether due to corrosion, impact or cracking, it’s essential to intervene quickly to avoid complications. Here are the essential steps for effectively replacing a defective pipe section.

1. Identify the section to be replaced

Before starting any work, it’s important to pinpoint the exact location of the damaged area. An apparent leak is easily detected by visible traces of moisture or leakage. For a hidden leak, look out for signs such as a drop in water pressure, stains on the walls or abnormally high water consumption. A more thorough inspection can be carried out with an inspection camera or acoustic detector.

2. Turn off water supply

Before any work is carried out, the water supply must be shut off to prevent leaks during replacement. Then check that all remaining water has drained away by opening a tap near the pipe in question.

3. Prepare the necessary equipment

Replacing a section of pipe requires the right tools and materials. Depending on the type of pipe (PVC, copper, PER), here’s what you’ll need:

• A hacksaw or pipe cutter to remove the defective part
• A suitable fitting (repair sleeve, compression fitting, weld)
• Sealing tape or joint compound, depending on the type of connection
• File or sandpaper to smooth cut ends

4. Cut out damaged area

Use a pipe cutter or saw to cleanly remove the defective pipe section. Be sure to cut straight to facilitate assembly of the new parts. Once the cut has been made, deburr the ends with a file to ensure a perfect fit.

5. Install the new section

The connection method depends on the type of piping:

• For copper pipes: solder the new section using a flashlight and a tin/lead alloy. Be sure to apply a stripper before soldering to ensure good adhesion.
• For PVC pipes: apply special glue to the fittings and press the new section into place, maintaining pressure for a few seconds.
• For PER or multilayer pipes: use a compression fitting or quick-connect coupling, without the need for welding.

6. Check for leaks and turn on water

Before closing a trench or wall, it’s essential to test the installation. Gradually reopen the water supply and check all connections for leaks. If everything is watertight, you can close the work area and put the system back into service as normal.
