Tools and Materials You’ll Need
Before diving into repairs, make sure to gather the following tools and materials:
- PVC pipe cutter or hacksaw
- Replacement PVC pipe and fittings
- PVC primer and cement

- Measuring tape
- Marker pen
- Protective gloves and safety glasses
Step-by-Step Instructions for Fixing a Leak
Step 1: Verify the Leak’s Location
Pinpoint the exact area in your PVC sewer pipe where the leak originates. A close inspection will often reveal visible cracks or dripping water. In some cases, you may need to run water through the pipe to identify the issue.
Step 2: Prepare the Area
Shut off the water supply to the area connected to the leaking pipe. Allow the pipe to dry completely. This is especially crucial, as PVC cement won’t adhere correctly to wet surfaces.
Step 3: Cut Out the Damaged Section
Using a PVC pipe cutter or hacksaw, remove the broken or cracked portion of the pipe. Use measuring tape to cut a replacement pipe of the same exact length.
Step 4: Smooth the Edges
Make sure the edges where you cut are smoothany roughness can jeopardize the integrity of the repair. Use sandpaper or a file to clean up edges.
Step 5: Attach the Replacement Pipe
Apply a layer of PVC primer to the ends of the pipe and the fittings. Follow this step by adding a coat of PVC cement. Quickly join the new pipe into place before the cement starts to set.
Tip: Ensure the pipe is aligned correctly to avoid problems during use.
Step 6: Test for Leaks
Turn the water supply back on and test your repair to ensure no further leaks are present. If additional leaks are observed, apply an extra layer of PVC cement or reattach the fittings as needed.
Temporary Fixes for Emergencies
In some cases, you may not have the necessary tools or time. For such emergencies, you can use these temporary methods:
- Wrap epoxy putty around the damaged area to seal the leak temporarily.
- Use duct tape or rubber tape for a short-term fix.
